Denver, CO Commercial Roofing FAQs

Welcome to Baseline Roofing and Solar's Commercial FAQ page. Here you'll find answers to the most common questions about commercial roofing systems, maintenance, storm damage, and our services across Denver and Colorado. Whether you're researching TPO, EPDM, or PVC systems, planning a replacement, or need emergency repair guidance, these frequently asked questions provide the technical information and practical insights you need to make informed decisions about your commercial property's roofing investment.

Frequently Asked Questions: Commercial Roofing in Denver

  • How long does a commercial roof last in Denver's climate?+

    Service life depends heavily on system type, installation quality, and exposure. In Denver, a properly installed TPO or PVC single-ply system typically lasts 20 to 30 years, EPDM 25 to 30+ years, modified bitumen 20 years, built-up systems 25 to 30+ years, and spray foam 20+ years with periodic recoating. Hail and severe weather events can shorten any of those timelines, which is why proper system specification, manufacturer-certified installation, and routine maintenance matter so much in this market.

  • How much does commercial roof replacement cost in Denver?+

    Commercial roof replacement is priced primarily by square footage, system type, insulation requirements, deck condition, and the complexity of penetrations and flashings. Pricing varies widely from one project to the next, which is why we provide free, written, on-site estimates rather than ballpark figures. After inspecting your roof, we will explain exactly what is driving the pricing on your specific building.

  • Should I repair or replace my commercial flat roof?+

    In general, repair makes sense when the existing system has significant remaining service life and the damage is localized. Replacement makes more sense when the membrane is widely degraded, insulation is saturated, leaks are recurring, or the system is past its expected service life. A roof coating or recover system can sometimes bridge the gap and add years to a roof that is not yet ready for full replacement. Our inspection report will lay out the options honestly so you can make the right call for your building.

  • Does insurance cover commercial roof damage from hail?+

    Most commercial property insurance policies cover hail damage to commercial roofs, but coverage details, deductibles, and depreciation terms vary substantially between policies. We document hail damage thoroughly with photos, measurements, and reports, write a detailed scope of work, and represent property owners through the claims process to help ensure you receive the full benefit your policy provides.

  • How quickly can you respond to a commercial roof emergency in Denver?+

    Active leaks and storm damage cannot wait. We prioritize emergency commercial roof repair calls and dispatch crews to stabilize your roof and protect your building as quickly as our schedule allows. After hours and weekends, call our main line and follow the emergency prompts.

  • Are roof coatings a good option for Denver commercial buildings?+

    For many commercial buildings, yes. Silicone, acrylic, and other elastomeric coatings can extend the life of an aging roof at a fraction of the cost of replacement, often qualify for a new manufacturer warranty, and improve solar reflectivity for energy savings. Coatings only work on suitable substrates, however, a roof that is too far gone needs replacement. Our inspection will tell you honestly whether your roof is a good candidate.

  • Do you handle commercial solar panel removal and reset for roof replacements?

    Yes. If your commercial building has rooftop solar and the roof needs to be replaced, we coordinate the detach and reset of your solar array as part of the project so you do not need to manage two separate contractors.

Frequently Asked Questions: Hiring a Denver Commercial Roofing Contractor

  • How do I know if a commercial roofing contractor in Denver is legitimate?+

    Verify three things: a current Colorado contractor license for the work being performed, an active certificate of insurance covering general liability and workers' compensation, and at least one current manufacturer certification for the system being proposed. Beyond that, look for a written, detailed proposal, accessible references, and a clear answer to the question "who is my point of contact during the project?" If a contractor balks at any of those, walk away.

  • What's the difference between a residential and commercial roofing contractor?+

    Commercial roofing contractors specialize in low-slope and flat roof systems, TPO, EPDM, PVC, modified bitumen, built-up, spray foam, and coatings, installed on much larger square footage than residential. The materials, installation procedures, equipment, manufacturer certifications, and code requirements are all different. Residential roofers who occasionally take on small commercial projects often lack the certifications needed to register manufacturer warranties, which can leave property owners exposed.

  • How long does a commercial roofing project take?+

    Project duration depends on square footage, system type, deck condition, weather, and operational constraints. A small commercial repair may take a single day. A 20,000-square-foot tear-off and replacement typically runs one to two weeks. Larger projects scale from there. We provide a written timeline as part of every proposal and update you proactively if conditions change.

  • Can you work without disrupting my business operations?+

    Yes, in nearly every case. We coordinate work hours, equipment staging, and crew movement around your operations. And we can perform work after hours, on weekends, or in phases when needed. Tell us what your operational constraints are at the estimate stage and we'll build the project plan around them.

  • What manufacturer certifications does Baseline hold?+

    Baseline holds certifications with all of the major commercial roofing manufacturers, including Carlisle, Versico, GAF, Mule-Hide, Firestone, and Johns Manville. We can specify and install systems from any of them. And we choose the system that best fits the building rather than pushing one brand across every project.

  • Do you offer warranties on your commercial roofing work?+

    Yes, two of them. Every system we install carries a manufacturer warranty (terms vary by system, often 20 to 30 years on commercial-grade systems), and Baseline backs the installation itself with a workmanship warranty. We'll walk you through the specific terms of both warranties as part of the proposal review.

  • Can I hire Baseline for ongoing commercial roof maintenance?

    Yes. Scheduled inspections and preventive maintenance are the most cost-effective way to maximize the service life of any commercial roof. We can structure a maintenance program tailored to your building, your system, and your budget.

Frequently Asked Questions: Commercial Flat Roof Replacement in Denver

  • How long does a commercial flat roof replacement take?+

    Project duration depends on square footage, system type, weather, and complexity. A 5,000 to 10,000 square foot single-ply replacement typically takes one to two weeks. A 50,000+ square foot project may run several weeks. We provide a written timeline as part of every proposal and update you proactively if weather or unforeseen conditions affect the schedule.

  • Can my building stay open during the replacement?+

    In nearly every case, yes. We coordinate work areas, equipment staging, and crew movement around your tenants and operations. For sensitive operations or for weekend-only work, we can phase the project or schedule outside business hours. Tell us your operational constraints at the estimate stage and we'll plan around them.

  • How long will my new commercial flat roof last in Denver's climate?+

    Properly installed: TPO and PVC typically deliver 20 to 30 years, EPDM 25 to 30+ years, modified bitumen and built-up systems 20 to 30 years, and SPF 20+ years with periodic recoating. Manufacturer warranties on commercial systems commonly run 20 to 30 years when installed by a certified contractor, which is one of the reasons certifications matter so much.

  • Do I need to remove the old roof, or can the new roof go over it?+

    Both options exist. Recover (roof-over) installations are faster and cheaper but only work when the existing system and insulation are sound and code allows it. Tear-off and full replacement is more thorough, lets us inspect and address the deck and insulation, and resets the manufacturer warranty. We'll evaluate which option is appropriate for your building and explain the trade-offs in writing.

  • Is commercial roof replacement covered by insurance after a hail or storm event?+

    Most commercial property insurance policies cover roof replacement when damage from a covered event (hail, wind, etc.) makes the existing system uneconomical to repair. Coverage details, deductibles, and depreciation terms vary widely. We document storm damage thoroughly, write a detailed scope of work, and represent property owners through the claims process to help you receive the full benefit your policy provides.

  • What warranty comes with a commercial flat roof replacement?+

    Two warranties: the manufacturer's product warranty (typically 20 to 30 years on commercial-grade systems, registered to your building once we install per manufacturer specification) and Baseline's workmanship warranty on the installation itself. Both are provided in writing at project close-out.

  • Can you replace a commercial roof with solar panels installed?

    Yes. We coordinate detach and reset of existing rooftop solar arrays as part of replacement projects so you don't have to manage two separate contractors. The solar array is removed before tear-off, the new roof is installed, and the array is then reset and re-commissioned.

Frequently Asked Questions: Commercial Flat Roof Installation in Denver

  • How long does a commercial flat roof installation take?+

    Project duration depends on square footage, system type, weather, and project complexity. A 5,000 to 10,000 square foot single-ply install on a straightforward building typically runs one to two weeks. Larger and more complex projects scale from there. We provide a written timeline as part of every proposal and update you proactively if conditions affect the schedule.

  • Do you install commercial roofs on new construction projects?+

    Yes, new construction is a significant portion of the work we do. We work as a roofing subcontractor under general contractors, coordinate with other trades, hit project schedules, and document our work for the GC's records. We're equally comfortable with one-off custom buildings and tract commercial development.

  • Can you install a commercial roof in winter in Denver?+

    Yes, with caveats. Many commercial roofing systems install year-round in Denver, but cold-weather installs require attention to material temperatures, adhesive cure times, and snow clearing. Some systems and adhesives are temperature-sensitive enough that we may schedule installation for warmer windows. We'll tell you what's possible based on your specific project.

  • What's the difference between roof installation and roof replacement?+

    Roof replacement always involves removing an existing roof first, then installing a new system in its place. Roof installation as a standalone service typically refers to new construction, putting a roof on a building for the first time. The actual installation craft is the same in both cases; the difference is what comes before.

  • Do you install roof coatings or just full systems?+

    Both. We install full roof systems on new construction and re-roof projects. And we install protective coatings on existing roofs as a stand-alone service. Coatings are excellent for extending the life of an existing roof at a fraction of replacement cost when the underlying system is sound.

  • Will my new commercial roof come with a warranty?+

    Yes. New commercial roof installations carry two warranties: a manufacturer warranty (typically 20 to 30 years on commercial-grade systems, registered to the building owner) and Baseline's workmanship warranty on the installation itself. Both are documented in writing at project close-out.

  • Can you coordinate with our general contractor and other trades?

    Yes. On new construction projects, we work directly with the GC's superintendent and coordinate with other trades, particularly mechanical, electrical, and plumbing teams whose work intersects with the roof. We hit our schedule windows, keep the site clean, and communicate proactively when conditions change.

Frequently Asked Questions: Commercial Flat Roof Repair in Denver

  • How quickly can you respond to a commercial flat roof repair call?+

    For non-emergency repair calls, we typically schedule an on-site inspection within a few business days, with the repair scheduled around weather and your operations. For active leaks and emergencies, we move much faster, see our Emergency Commercial Roof Repair page for that workflow.

  • Will repairing my commercial roof void the manufacturer warranty?+

    Not when the repair is done properly. Manufacturer warranties typically require that repairs use the same manufacturer's approved materials and methods, performed by a certified contractor. Because we hold certifications across all the major commercial manufacturers, we can perform warranty-compliant repairs on the systems we work on. Improperly done repairs, including amateur or handyman patches, can void the warranty, which is why we recommend leaving commercial roof repair to certified contractors.

  • How do I know if my commercial roof needs repair or full replacement?+

    It depends on the age of the system, the extent of the damage, the condition of the insulation underneath, and the pattern of failures. Localized damage on a roof with significant remaining service life is almost always a repair. Widespread damage, saturated insulation, or a system past its service life is more often a replacement candidate. Our inspection will tell you straight which path fits your specific roof.

  • How long does a commercial flat roof repair take?+

    Most localized repairs, failed seams, punctures, flashing replacements, drain repairs, take a single day or less on site. Larger repairs involving multiple areas or significant scope can run several days. We give you a clear timeline as part of every written estimate.

  • Are commercial roof repairs covered by insurance?+

    Repairs are typically covered when the damage is caused by a covered event under the property's insurance, most commonly hail or wind damage. Wear and tear and aging of the system itself are generally not covered. If your repair is potentially insurance-related, we document the damage thoroughly so you have what you need to file a claim.

  • Can you repair a commercial roof you didn't originally install?+

    Yes. Most of our repair work is on roofs originally installed by other contractors. We identify the system, source manufacturer-compatible materials, and execute the repair to current manufacturer standards. Where possible, we preserve the existing manufacturer warranty in the process.

  • How much does commercial flat roof repair cost in Denver?

    Repair pricing varies by system type, scope, accessibility, and material costs. A simple single-puncture patch is at the low end; rebuilding a complex flashing or addressing widespread seam failure runs higher. Rather than quote ballpark numbers that mislead, we provide a written estimate after inspecting the actual roof.

Frequently Asked Questions: Emergency Commercial Roof Repair in Denver

  • How fast can you respond to a commercial roof emergency in Denver?+

    We respond as quickly as our schedule, road conditions, and weather safely allow. Active leaks during business hours typically get same-day response. After-hours calls are handled by our team based on the severity of the situation. Call us at (720) 780-0488 and we'll tell you straight what we can commit to.

  • Do you respond to commercial roof emergencies after hours and on weekends?+

    Yes. Commercial roof emergencies don't wait for business hours, and neither do we. Call (720) 780-0488 anytime, after-hours calls reach our emergency response line.

  • Will you install a tarp on my commercial roof if you can't do a permanent repair right away?+

    Yes. Tarping or otherwise stabilizing the roof is often the right first step in an emergency, especially during active weather or in temperatures that won't allow proper permanent repair. We make it clear that the tarp is temporary and we follow up with a permanent repair as soon as conditions allow.

  • How much does emergency commercial roof repair cost?+

    Emergency repair pricing depends on the scope of damage, time of day, and complexity of access. We provide pricing as part of the on-site assessment and document everything for potential insurance reimbursement. Don't let cost concerns delay the call, the cost of an emergency repair is almost always far less than the cost of letting water keep entering the building.

  • Will my insurance cover emergency commercial roof repair?+

    Most commercial property insurance policies cover emergency repairs caused by covered events (hail, wind, falling objects, storm damage). Policies typically exclude wear and tear or aging-related failures. We document the cause of the failure thoroughly in our reports so your carrier has what they need to evaluate the claim.

  • Can you repair an emergency on a commercial roof you didn't originally install?+

    Yes, most of our emergency repair work is on roofs originally installed by other contractors. We identify the system, source manufacturer-compatible emergency materials, and stabilize the leak quickly. Where the original installation has a manufacturer warranty, our repair preserves it wherever possible.

  • What's the difference between emergency repair and standard commercial flat roof repair?

    Emergency repair is about stopping active damage right now, typically through stabilization first, with permanent repair to follow. Standard commercial flat roof repair is scheduled work on a non-emergency basis, performed in a single visit when conditions allow proper diagnosis and permanent repair. Emergency calls get prioritized over routine scheduled work.

Frequently Asked Questions: Commercial Roof Inspection in Denver

  • How often should a commercial roof be inspected in Denver?+

    At minimum, once a year. The gold standard is twice a year, once in spring after the worst of the freeze-thaw cycle and snow loading, and once in fall before winter sets in. Additional inspections after major hail events, windstorms, or significant weather incidents are essential, since hail damage in particular often isn't visible from inside the building.

  • How long does a commercial roof inspection take?+

    A typical commercial roof inspection takes one to three hours on site, depending on the size of the roof, the system, and the level of detail required. Larger or more complex inspections, particularly forensic and due-diligence inspections, may take longer. The written report is typically delivered within a few business days of the inspection.

  • How much does a commercial roof inspection cost in Denver?+

    Pricing depends on the type of inspection. A free assessment for a property owner considering work is included at no cost. Paid inspections, pre-purchase, forensic, comprehensive condition reports, are priced based on roof size and inspection scope. We'll quote the inspection up front before scheduling so you know exactly what you're getting and what you're paying.

  • Can you inspect a roof you didn't install?+

    Yes. Most of the inspections we perform are on roofs originally installed by other contractors. We're certified across every major commercial manufacturer, so we can identify the system, assess its condition, and document our findings against the manufacturer's specifications regardless of who installed it.

  • Do you provide documentation that I can submit to my insurance carrier?+

    Yes. Inspection reports following hail, wind, or storm damage include the photo documentation, measurements, and damage descriptions that insurance carriers need to evaluate claims. We can coordinate directly with your insurance adjuster if needed.

  • Will an inspection void my warranty?+

    No, the opposite. Most manufacturer warranties on commercial roofs require documented periodic inspection to remain valid. Our inspection reports satisfy that requirement and protect your warranty coverage.

  • What's the difference between a roof inspection and an estimate?

    An estimate is focused on pricing specific work you're considering, replacement, repair, or another service. An inspection is focused on documenting condition independent of any particular work. The two often overlap, but the deliverables and the depth of documentation differ. If you need a comprehensive condition report rather than a price for specific work, ask for an inspection rather than an estimate.

Frequently Asked Questions: Commercial Roof Insurance Claims in Denver

  • Do I have to file a claim before getting an inspection?+

    No. Most property owners schedule the inspection first, find out whether the damage is significant, and then make the claim decision based on what the inspection finds. An inspection that finds no significant damage saves you from filing a claim you don't need to file.

  • Will filing a claim raise my insurance premium?+

    Possibly. Commercial property insurance pricing reflects loss history, and carriers do consider past claims at renewal. Whether a specific claim affects your specific renewal depends on the carrier, the size of the claim, and your overall loss history. Your insurance broker is the right person to discuss this with for your specific situation.

  • How long does a commercial roof insurance claim take to resolve?+

    Timelines vary widely. Simple claims with cooperative carriers can resolve in a few weeks. Complex claims with disputed scope, multiple supplements, or carriers that move slowly can take months. Thorough documentation up front and a properly written scope significantly shorten the timeline.

  • Can Baseline negotiate my claim with the insurance company?+

    No. Under Colorado law, roofing contractors are not licensed to act as insurance adjusters or negotiate claims. We document damage, write repair scopes, and communicate with adjusters about the work itself, but the claim is between you and your carrier. If you need claim negotiation help, the appropriate professional is a licensed public adjuster.

  • What documentation do I need for a commercial roof insurance claim?+

    At minimum: a written inspection report from a qualified contractor with photos and measurements, the date and weather of the event causing damage, a written scope of work for the repair or replacement, and any supplemental documentation as additional damage is discovered during the work. We provide all of this for our clients on insurance-related claims.

  • My adjuster's scope is much lower than your estimate. What happens next?+

    Differences between the adjuster's scope and the contractor's scope are common and don't necessarily mean the claim is being denied. We document the gaps, missing scope items, code upgrades, manufacturer-spec materials, supplemental damage, and provide that documentation to you. You then submit a supplement to your carrier requesting they review the additional scope. Most legitimate gaps get resolved through this process.

  • Should I hire a public adjuster for a commercial roof claim?

    Public adjusters are licensed professionals who represent property owners in claims against insurance carriers. For larger or more complex commercial claims, particularly contested claims, total losses, or business interruption claims, many property owners find a public adjuster valuable. For smaller, more straightforward claims, the cost of a public adjuster (typically a percentage of the claim) may exceed the value they add. This decision is yours and ideally discussed with your insurance broker or attorney.

Frequently Asked Questions: Commercial Storm & Hail Damage Roof Inspection in Denver

  • Is a post-storm commercial roof inspection free?+

    In most cases, yes. When you're considering work as a result of storm damage and contacting us as a property owner, the post-storm inspection is included at no cost as part of the assessment. Larger forensic inspections, third-party inspections for property managers documenting condition without intent to repair through us, and pre-purchase post-storm inspections are sometimes priced separately. We'll always tell you up front what the inspection cost will be.

  • How quickly should I schedule an inspection after a hailstorm?+

    As soon as practically possible, ideally within days of the event, and certainly before the next major storm. Most commercial property insurance policies require prompt notification of damage. Inspection within days of the event also captures damage while it's fresh and clearly attributable to the storm in question.

  • Will an inspection guarantee my insurance will pay for repairs?+

    No. We document damage and write repair scopes, but the insurance claim is between you and your carrier. What we can do is provide thorough, professional documentation that gives you the best basis to support the claim. We never promise specific claim outcomes. That's not legal for a contractor to do, and it's not how the claim process actually works.

  • Can hail damage be invisible from inside my building?+

    Yes, and this is one of the most important reasons to schedule post-storm inspection. Hail can fracture or compromise commercial roof membranes without producing visible interior leaks for weeks or months. By the time the leak surfaces, the insurance claim window may have closed and the damage to insulation may be substantial. Don't wait for visible leaks to inspect.

  • What size hail causes commercial roof damage?+

    Hail of approximately one inch in diameter or larger is generally capable of damaging commercial roof membranes, though damage thresholds vary by system, system age, and impact angle. Aged single-ply membranes can be damaged by smaller hail than fresh material. We don't rely on a single threshold, we inspect when there's any reasonable chance of damage.

  • Can you inspect a commercial roof you didn't install?+

    Yes. The vast majority of post-storm inspections we perform are on roofs originally installed by other contractors. We're certified across every major commercial manufacturer, which means we know how to inspect each system properly regardless of who installed it.

  • How long does a post-storm commercial roof inspection take?

    On-site time typically runs one to three hours depending on the size and complexity of the roof. For larger commercial buildings, drone imagery accelerates the process while improving documentation quality. The written report is delivered within a few business days of the inspection, faster on time-sensitive insurance situations.

Frequently Asked Questions: Commercial Storm & Hail Damage Flat Roof Repair in Denver

  • How quickly should I schedule storm damage repair?+

    As soon as practical after damage is documented and an insurance scope (if applicable) is approved. Don't rush the inspection or the documentation, those need to be thorough, but once the scope is approved, the actual repair work should be scheduled without unnecessary delay so the next storm doesn't compound the damage.

  • Will my insurance pay for the repair?+

    Storm damage caused by covered events (hail, wind, falling objects) is typically covered under most commercial property insurance policies, though specific coverage varies by policy. We document the damage thoroughly to support your claim. Whether the carrier ultimately pays for repair is between you and the carrier, we cannot promise specific claim outcomes.

  • Will repair work void the manufacturer warranty on my roof?+

    Not when the repair is done properly. Manufacturer warranties typically require that repairs use the same manufacturer's approved materials and methods, performed by a certified contractor. Because we are certified across every major commercial manufacturer, we can perform warranty-compliant repairs that preserve the existing warranty on the unaffected portions of the roof.

  • How long does a storm damage repair take?+

    Project duration depends on the scope of damage, weather, and material lead times. Localized repairs on a single area typically take a day or less on site. Larger repairs spanning multiple roof sections or system components can run several days. Material lead times for less common membrane types or specific colors can sometimes be the longest variable.

  • What if more damage is found during repair than the insurance scope covers?+

    This happens regularly, particularly when wet insulation or additional storm damage becomes visible during repair work. We document the additional findings with photos and measurements and provide that documentation to you for submission to the carrier as a claim supplement. Most legitimate supplemental findings are approved through this process.

  • Can you repair storm damage on a roof you didn't install?+

    Yes, most of our storm damage repair work is on roofs originally installed by other contractors. We identify the system, source manufacturer-compatible materials, and execute the repair to current manufacturer standards. Where possible, we preserve any existing manufacturer warranty in the process.

  • Why should I use a Denver-based contractor for storm repair?

    Storm chasers do not stick around. The contractor that did the work needs to be accessible months and years later when warranty questions or follow-up concerns surface. Local Denver-based contractors with permanent operations and local references provide the long-term accountability that insurance-funded repair work specifically needs. Out-of-state operators typically cannot.

Frequently Asked Questions: Commercial Storm & Hail Damage Flat Roof Replacement in Denver

  • Will my insurance pay for a full commercial roof replacement after a storm?+

    Most commercial property insurance policies cover storm-driven replacement when the damage from a covered event makes the existing system uneconomical to repair. Coverage details, deductibles, and depreciation handling vary substantially by policy. We document the damage thoroughly and write a replacement scope that reflects what the building needs, but the claim is between you and your carrier, we cannot guarantee specific claim outcomes.

  • How long does a storm-driven roof replacement take?+

    Insurance approval typically takes a few weeks from claim opening through approved scope, sometimes longer on contested or supplement-heavy claims. Once the claim is approved, the actual work runs from one week to several weeks depending on the size of the roof, the system, weather, and complexity. We give you a written timeline as part of the contract and update you proactively if conditions change.

  • What's the difference between ACV and RCV on a roof claim?+

    Replacement Cost Value (RCV) policies pay the actual cost to replace the roof, typically with the depreciation released as recoverable upon completion of the work. Actual Cash Value (ACV) policies pay the depreciated value of the roof, which on older roofs can be a fraction of replacement cost. RCV produces dramatically better outcomes for property owners. Read your policy or ask your broker about your specific coverage.

  • Should I upgrade to an impact-resistant system during replacement?+

    It's worth strongly considering on Denver-area commercial buildings. Class 4 impact-rated systems and reinforced single-ply membranes offer materially better hail performance than standard systems, often at a 5%-20% premium. Insurance premium discounts where available and reduced repair costs over the system's service life often make the math work favorably, especially given that Denver buildings are likely to face additional hail events over the new roof's life.

  • Can I add code upgrades to my insurance-paid replacement?+

    If your policy includes Law and Ordinance coverage, code-required upgrades during the replacement are typically covered up to the policy's specific limits. We identify the code-required upgrades during scope development. Items the policy doesn't cover can still be added to the project at your cost. We'll quote them transparently as separate line items.

  • Can you handle solar panel detach and reset during a replacement?+

    Yes. We coordinate the detach-and-reset of existing rooftop solar arrays as part of the replacement scope, so you don't need to manage two separate contractors. The array is removed before tear-off, the new roof is installed, and the array is reset and re-commissioned at completion.

  • Why not use the storm-chaser contractor that's offering a great price?

    Storm-chasing operations don't stick around. Out-of-state contractors that follow major storms typically leave the Denver area within a year of finishing local work, sometimes within months. Their warranties are theoretically valid; in practice they're worthless because the company can't be reached when called. On a 20-30 year warranted system, you need a contractor that's actually still here to honor the warranty. Local Denver-based contractors with verifiable history, manufacturer certifications, and permanent operations are the right answer for storm-driven replacement work.

Frequently Asked Questions: Storm & Hail Damage Roof Insurance Claims in Denver

  • How long after a storm do I have to file an insurance claim?+

    Reporting deadlines vary by policy. Most commercial property policies require prompt notification of damage, some specify within 30 days, others give longer windows. Filing within days of the event is always the cleaner path. Read your specific policy or ask your broker about the exact deadline that applies to your coverage.

  • Does my insurance cover hail damage to my commercial roof?+

    Most commercial property insurance policies cover hail damage caused by qualifying hail events, subject to your specific policy terms, deductibles, and exclusions. Older roofs, cosmetic-only damage on certain policies, and pre-existing conditions are common areas where coverage may be limited or excluded. Read your policy or talk to your broker about your specific situation.

  • What's the difference between a wind/hail deductible and a regular deductible?+

    Many commercial property policies have a separate, higher deductible specifically for wind and hail damage, sometimes a fixed dollar amount, sometimes a percentage of the insured value. This can dramatically increase the out-of-pocket cost on a hail claim compared to other types of claims. Check your declarations page or ask your broker if you're unsure.

  • Can Baseline negotiate my storm claim with the insurance company?+

    No. Under Colorado law, roofing contractors cannot legally negotiate claims or act as insurance adjusters. We document damage, write repair scopes, attend joint inspections with adjusters, and provide documentation for supplements, but the claim itself is between you and your carrier. Anyone offering to "handle your insurance claim" as a contractor is operating outside Colorado law.

  • My adjuster's scope is much lower than your repair estimate. What happens?+

    This is common on storm claims and doesn't necessarily mean the claim is being denied. Adjuster scopes routinely miss code-required upgrades, manufacturer-spec materials, and supplemental damage. We document the gaps in writing and provide that documentation to you for submission as a claim supplement. Most legitimate gaps get resolved through the supplement process.

  • What if my hail damage didn't cause an immediate leak?+

    Hail damage frequently doesn't produce an immediate visible leak. That's why post-storm inspection matters so much. Fractured membrane, granule loss, and impact-damaged seams can take months to start visibly leaking, but the damage is real and is typically covered if documented within the policy's reporting window. Don't wait for visible interior damage to schedule an inspection after a hail event.

  • Will filing a hail claim raise my insurance premium?

    Possibly. Commercial property insurance pricing reflects loss history. Whether a specific claim affects your specific renewal depends on the carrier, the size of the claim, and your overall portfolio loss history. Your insurance broker is the right person to discuss this with for your specific situation. Most commercial property owners don't avoid filing legitimate hail claims, the cost of the unaddressed damage usually exceeds any premium impact.

Frequently Asked Questions: Commercial Roof Coatings in Denver

  • How long does a commercial roof coating last?+

    Manufacturer warranties typically run 10, 15, or 20 years depending on the system, the coating thickness, and the substrate. Properly applied silicone coatings on suitable roofs commonly perform for 15 to 20+ years before recoating is needed. Acrylics typically deliver 10 to 15 years. Manufacturer warranties depend on certified installation, periodic inspection, and recoating at the appropriate interval.

  • How much does a commercial roof coating cost compared to replacement?+

    Coatings typically cost 30% to 60% less per square foot than full tear-off and replacement, depending on the coating system, the condition of the existing roof, and the prep work required. The cost difference is one of the main reasons coatings are attractive, but the right answer depends on whether the underlying roof can actually support a coating long-term. We'll give you both numbers so you can decide.

  • Will a coating stop active leaks on my commercial roof?+

    On most aging commercial roofs with surface-level failures, yes, a properly applied coating stops leaks at seams, flashings, penetrations, and surface degradation points. On roofs where the underlying system has failed (saturated insulation, damaged decking, system-wide membrane failure), a coating won't fix the underlying problem and isn't the right solution. The inspection determines which situation you're in.

  • Can a coating be applied over any commercial roof system?+

    Most major commercial roofing systems can be coated with the right coating system, including TPO, EPDM, PVC, modified bitumen, built-up, spray foam, and metal. Each substrate has specific compatibility requirements (which coating chemistries can be used, what primer is needed, what surface prep is required), and not every coating works on every substrate. We specify based on the actual roof, not a generic recommendation.

  • Do roof coatings qualify for ENERGY STAR or cool-roof rebates?+

    Many reflective white silicone and acrylic coatings carry ENERGY STAR ratings and meet cool-roof reflectivity requirements. Specific rebates and tax incentives vary by program, year, and jurisdiction, talk to your tax advisor or local utility about what's currently available in your specific area.

  • How disruptive is the coating application to my building operations?+

    Coating application is significantly less disruptive than tear-off and replacement. There's no debris, no demolition, no roof opened to weather. Crews work on the roof with minimal noise penetration into the building below. Most commercial properties remain fully operational throughout the coating process.

  • Can a coating be applied in winter in Denver?

    Cold-weather application has limits. Most coating systems require minimum substrate and air temperatures to cure properly, typically 40°F to 50°F and rising, so winter application windows in Denver are limited. We schedule coating work for warmer months when temperature and weather conditions support proper application and cure.

Frequently Asked Questions: Commercial Silicone Roof Coatings in Denver

  • How long does a silicone roof coating last?+

    Manufacturer warranties typically run 15 to 20 years on properly installed silicone systems, with some premium systems offering 25-year warranties. Real-world service life is often longer than the warranty period when the original application was done correctly and periodic inspection catches any issues early.

  • How much does silicone roof coating cost vs. acrylic in Denver?+

    Silicone material costs more per gallon than acrylic, and the installed cost on a typical commercial flat roof typically runs 20% to 40% higher than equivalent acrylic application. The cost premium is worth paying when ponding water resistance or high-altitude UV stability matter, and isn't worth paying on roofs where those factors don't apply.

  • Can silicone be applied over my existing TPO/EPDM/PVC/modified bitumen/BUR/SPF roof?+

    Yes, silicone is compatible with all of those substrates with proper surface preparation and primer where required. SPF roofs are particularly common candidates for silicone recoat because silicone is the standard top coat for new SPF systems. We confirm compatibility and specify the correct primer (if any) during the inspection.

  • Will a silicone coating stop my commercial roof from leaking?+

    On most aging commercial roofs with surface-level failures, yes. Silicone bonds to seams, flashings, and penetrations to create a continuous waterproof layer that addresses the most common leak points on aging single-ply, modified bitumen, and built-up roofs. Roofs with saturated insulation or system-wide failures need replacement, not coating.

  • Is silicone the right coating for my building?+

    It depends on the substrate, the drainage, the UV exposure, your service-life expectations, and your budget. Silicone is the right answer often, but not always. Our inspection will tell you whether silicone is the right coating chemistry, whether acrylic would be a better fit for your situation, or whether replacement actually makes more sense.

  • Can a silicone-coated roof be coated with anything else later?+

    No. Once silicone is on the roof, future recoats must be silicone. No other coating chemistry will reliably adhere to cured silicone. This isn't a problem for owners who plan to maintain the silicone system long-term, but it's worth understanding before you choose silicone over a more flexible chemistry.

  • Is silicone coating ENERGY STAR rated?

    Most white silicone coatings from major manufacturers carry ENERGY STAR ratings and meet cool-roof code requirements where applicable. Specific products vary, we can confirm the rating for the system we're proposing on your project.

Frequently Asked Questions: Commercial Acrylic Roof Coatings in Denver

  • How long does an acrylic roof coating last in Denver?+

    Properly applied acrylic systems with manufacturer warranties typically deliver 10 to 15 years of service life in Denver. Service life depends heavily on substrate condition, application quality, and exposure, full sun roofs at altitude age coatings faster than shaded or partially-protected roofs.

  • Acrylic vs. silicone: which is better for my Denver commercial roof?+

    It depends on three things: drainage, budget, and service-life expectations. If your roof has ponding water, silicone is the clear answer, acrylic doesn't tolerate ponding. If drainage is good and budget matters, acrylic delivers strong cost-per-year value. If you want the longest-possible service life and ponding-immune performance regardless of cost, silicone wins. We assess your specific roof and tell you which fits.

  • Will an acrylic coating qualify for ENERGY STAR or cool-roof rebates?+

    Most major manufacturers' white acrylic coating systems carry ENERGY STAR ratings and meet cool-roof code requirements. Specific rebates and tax incentives vary by program, year, and jurisdiction, talk to your tax advisor or local utility about what's currently available in your area.

  • Can acrylic be applied over my existing TPO/EPDM/PVC/modified bitumen/BUR roof?+

    Yes, acrylic is compatible with most major commercial substrates with proper surface preparation and primer where required. We confirm compatibility and specify the correct primer during the inspection.

  • How much does acrylic roof coating cost compared to replacement?+

    Acrylic coating typically costs 50% to 70% less per square foot than full tear-off and replacement, depending on the underlying roof condition and prep work required. The cost-per-year math frequently favors acrylic when the underlying roof is sound and drainage is good.

  • How disruptive is acrylic application to my building operations?+

    Significantly less disruptive than tear-off and replacement. There's no debris, no demolition, no roof opened to weather. Crews work on the roof with minimal noise penetration into the building below. Most commercial properties remain fully operational throughout the application process.

  • Can I recoat an acrylic roof with silicone later?

    Yes, this is one of acrylic's advantages. Unlike silicone (which locks the roof into silicone-only future recoats), an acrylic-coated roof can be recoated with acrylic, silicone, or a different chemistry as conditions change. This flexibility makes acrylic attractive for owners who want to keep options open over the roof's life.

Frequently Asked Questions: Commercial Metal Roof Coatings in Denver

  • How long does a metal roof coating last?+

    Manufacturer warranties on properly applied metal coating systems typically run 10 to 20 years depending on the product, substrate, and application specifications. Real-world service life on well-applied systems with proper prep often runs 15 to 20+ years before recoating is needed.

  • How much does metal roof coating cost compared to metal roof replacement?+

    Metal roof restoration coating typically costs 50% to 75% less per square foot than full metal roof replacement, depending on the substrate condition, prep work required, and system specifications. Given how expensive metal roof replacement is, this is often the largest cost-savings comparison in commercial roof restoration.

  • Will a coating stop rust on my metal commercial roof?+

    Yes, when proper rust treatment is part of the system. Rust converters or rust-inhibiting primers neutralize active rust and prevent further progression. The top coat then seals out moisture and oxygen, addressing the conditions that cause new rust to start. Skipping the rust-treatment step is the most common cause of "coated" metal roofs that continue rusting underneath the coating.

  • Can a coating fix leaking fasteners on my metal roof?+

    Yes. The fastener-treatment step in a proper metal coating system addresses every fastener, re-driving loose ones, replacing failed ones, and sealing over each fastener head as part of the coating application. This is one of the most reliable benefits of metal roof restoration coatings.

  • Will the coating qualify my metal roof for cool-roof rebates or ENERGY STAR?+

    Most major manufacturers' white metal coating systems carry ENERGY STAR ratings and meet cool-roof code requirements. Specific rebates vary by program and jurisdiction, talk to your tax advisor or local utility about what's currently available.

  • Can you coat a metal roof that has hail damage?+

    Yes, and this is often the right approach when hail damage is functional but not structurally severe. We document the damage for any insurance claim, repair functional issues (rust starting at impact sites, paint system damage, panel-level repairs where needed), and apply the restoration system as part of the work. On metal roofs with widespread severe hail damage, replacement may be the right call instead, our inspection will tell you which.

  • How disruptive is metal roof coating application to my building operations?

    Significantly less disruptive than tear-off and replacement. There's no demolition and the roof is never opened to weather. Crews work primarily on the exterior, with minimal noise penetration into the building below. Most commercial properties remain fully operational throughout the application.

Frequently Asked Questions: Commercial Spray Foam Roofing in Denver

  • How long does a spray foam roof last?+

    With proper coating maintenance, an SPF roof can deliver 30+ years of service through periodic recoating. The foam itself is durable; the protective coating layer is what requires periodic renewal, typically every 15 to 20 years on silicone top coats. Without coating maintenance, the foam degrades rapidly once UV exposure starts. Maintenance is the single biggest variable in SPF service life.

  • How much does spray foam roofing cost in Denver?+

    SPF cost depends on foam thickness, coating system, substrate condition, and prep work required. Per square foot, SPF typically costs more than basic single-ply systems but is competitive with high-end membrane assemblies once you factor in the included insulation. On recover projects without tear-off, the total project cost can be significantly lower than a comparable tear-off and replacement with membrane.

  • Can spray foam be applied over my existing commercial roof?+

    Yes, in most cases. SPF can be applied over most existing commercial substrates, single-ply, built-up, modified bitumen, even metal, provided the existing system is structurally sound, dry, and properly prepared. Saturated insulation must be removed before SPF can go down. We confirm substrate suitability during inspection.

  • How is spray foam roofing repaired after hail damage?+

    Hail damage to SPF is repaired by spot-foaming impact craters back to a flush surface, then re-coating affected areas with the original protective coating system. Properly executed, hail repair on SPF restores the system to full performance. Repairs require an SPF-experienced contractor, generic flat-roof patching products don't work properly on foam.

  • Does SPF roofing qualify for ENERGY STAR or cool-roof rebates?+

    Most SPF systems with white silicone or acrylic top coats carry ENERGY STAR ratings and meet cool-roof code requirements. The combined effect of high R-value insulation plus reflective top coat often makes SPF one of the strongest energy-performance commercial roof systems available.

  • Can spray foam roofing be installed in winter in Denver?+

    Application windows are limited in cold weather. SPF requires substrate temperatures generally above 50°F and stable conditions during cure. Most SPF projects in Denver are scheduled for spring through fall when weather windows are reliable. Winter application is sometimes possible during warm spells but requires careful timing.

  • How do I know if my building is a good candidate for SPF?

    Strong candidates include re-roof projects where tear-off would be expensive or disruptive, buildings with complex roof geometry or many penetrations, properties with chronic ponding that would benefit from added slope, and energy-conscious building owners who value the high R-value SPF provides. Less ideal candidates include buildings with saturated insulation, projects where weather windows are unreliable, and situations where cost-per-square-foot is the only decision criterion. Our inspection will tell you straight whether SPF fits your specific building.

Frequently Asked Questions: Commercial TPO Roofing in Denver

  • How long does a TPO roof last in Denver?+

    Manufacturer warranties on commercial TPO typically run 15 to 30 years depending on membrane thickness and warranty type. Real-world service life on properly installed TPO from established manufacturers commonly meets or exceeds the warranty period. Hail and severe weather events can shorten any roof's service life, which is why thickness selection and impact-resistant options matter on Denver buildings.

  • How much does a TPO roof cost in Denver?+

    TPO pricing depends on square footage, membrane thickness (45/60/80-mil), installation method (mechanically-fastened vs. fully-adhered vs. induction-welded), insulation requirements, deck condition, and the complexity of penetrations. Per square foot, TPO is typically the most cost-competitive single-ply option for new commercial work. We provide written estimates after inspecting the actual roof.

  • Is TPO better than EPDM for Denver commercial buildings?+

    It depends on the building. TPO offers heat-welded seams, white reflectivity, and competitive pricing, making it the better choice for most general commercial applications in Denver. EPDM offers proven longevity, exceptional thermal cycling tolerance, and is typically available in long-life formulations, making it preferred on certain applications where those properties matter most. Our inspection and the building's specific use will tell us which fits better.

  • What thickness of TPO should I install?+

    For typical Denver commercial buildings, 60-mil is our most-recommended thickness, strong impact resistance, longer warranties than 45-mil, modest cost premium. For high-hail-risk areas, high-traffic roofs, or applications where the longest warranty term is valued, 80-mil is often worth the upgrade. We don't typically recommend 45-mil for Denver unless specific cost constraints require it and hail exposure is minimal.

  • Can a TPO roof be installed over my existing commercial roof?+

    In some cases, yes. TPO can be installed as a recover system over certain existing substrates when the existing roof is sound, dry, and code allows it. More often, a tear-off is preferable on aged roofs because it lets us inspect and address insulation, deck, and substrate issues that recover wouldn't reveal. Our inspection will tell you which approach makes sense.

  • Does TPO qualify for ENERGY STAR or cool-roof rebates?+

    Most major manufacturers' white TPO membranes carry ENERGY STAR ratings and meet cool-roof code requirements. Specific rebates and tax incentives vary by program, year, and jurisdiction, talk to your tax advisor or local utility about what's currently available.

  • How is hail damage repaired on a TPO roof?

    Hail-damaged TPO is repaired with manufacturer-approved patches heat-welded over the damaged area. Localized hail damage on a 60-mil or 80-mil membrane is straightforward to repair. Widespread hail damage may warrant full replacement, our post-storm inspection will tell you which applies.

Frequently Asked Questions: Commercial EPDM Roofing in Denver

  • How long does an EPDM roof last in Denver?+

    Manufacturer warranties on commercial EPDM typically run 20 to 30 years depending on thickness and warranty type. Real-world service life on properly installed EPDM commonly meets or exceeds the warranty, with well-maintained EPDM roofs from the 1980s and earlier still performing in many cases. The 50+ year track record gives EPDM data no other single-ply can match.

  • EPDM vs. TPO: which is better for my Denver commercial building?+

    It depends on the building. TPO offers heat-welded seams, white reflectivity, and competitive new-install pricing, making it the most common choice for new commercial work in Denver. EPDM offers proven longevity, exceptional thermal cycling tolerance, fewer seams from wider roll widths, and lower material cost, making it preferred on certain applications and budget-sensitive projects. Our inspection and the building's specific use will tell us which fits better.

  • How much does EPDM roofing cost in Denver?+

    EPDM cost depends on installation method (ballasted is typically cheapest, fully-adhered most expensive), membrane thickness, color (black is cheaper than white), and the complexity of the roof. Per square foot, EPDM material is generally lower-cost than TPO or PVC, though installation method choices can change the total project cost. We provide written estimates after inspecting the actual roof.

  • Is black or white EPDM better for my Denver commercial roof?+

    If summer cooling loads are a major concern (most Denver commercial buildings), white EPDM or a reflective coating is the right call, and at that point, white TPO often delivers better economics than white EPDM. Black EPDM is typically the right call when cost is the priority and the building's energy profile is dominated by winter heating rather than summer cooling, or when reflective performance isn't a concern for the specific building type.

  • Can hail damage EPDM, and how is it repaired?+

    Yes, severe hail can damage EPDM, typically as bruising, tearing, or seam damage rather than the punctures more common on thermoplastics. Repair uses manufacturer-approved EPDM patches and splice tape, applied with proper substrate prep. Localized hail damage on a sound EPDM membrane is straightforward to repair. Widespread damage on aged EPDM may warrant replacement, our post-storm inspection will tell you which applies.

  • What thickness of EPDM should I install?+

    60-mil is the commercial standard and our most-recommended thickness for typical Denver commercial buildings. 45-mil is the budget option for protected applications with minimal hail exposure. 90-mil is the premium option for high-hail-risk areas, high-foot-traffic roofs, and applications where the longest warranty and strongest impact resistance matter. We recommend 60-mil minimum for most Denver buildings, with 90-mil consideration on hail-exposed applications.

  • Can EPDM be applied as a recover system over my existing commercial roof?

    In some cases, yes. EPDM can be installed as a recover over certain existing substrates when the existing roof is sound and code allows it. Often, tear-off and re-roofing is preferable on aged commercial roofs because it lets us inspect the deck, insulation, and substrate. Our inspection will tell you which approach fits your building.

Frequently Asked Questions: Commercial PVC Roofing in Denver

  • How long does a PVC roof last in Denver?+

    Manufacturer warranties on commercial PVC typically run 20 to 30 years depending on membrane thickness and warranty type. Real-world service life on properly installed PVC commonly meets or exceeds the warranty. Older PVC formulations sometimes show plasticizer-migration issues at advanced age; modern formulations have largely addressed this through improved plasticizer chemistry.

  • Is PVC really the only acceptable roof for restaurants?+

    In effect, yes, for buildings with active commercial kitchen exhaust. TPO and EPDM degrade under grease and animal fat exposure, leading to premature failure on restaurants. Most commercial roofing manufacturers will not warranty TPO or EPDM installations adjacent to grease exhaust. PVC is essentially immune to grease attack and is the industry standard for food service applications.

  • How much does PVC roofing cost compared to TPO in Denver?+

    PVC typically costs 20-40% more per square foot than equivalent TPO, depending on membrane thickness, manufacturer, and installation method. The cost premium is justified by chemical resistance on applications that need it; on general commercial buildings without those needs, the premium isn't worth paying.

  • What is plasticizer migration and should I worry about it?+

    Plasticizers are additives that keep PVC flexible. Over decades of service, they can slowly migrate out of the membrane, gradually reducing flexibility. Modern PVC products use higher-molecular-weight plasticizers that migrate much more slowly than early-generation products. On a properly specified modern PVC roof, plasticizer migration is unlikely to affect performance during the warranty period, though it remains a chemistry-level consideration for very long service applications.

  • What thickness of PVC should I install?+

    60-mil is the commercial standard and our most-recommended thickness for typical Denver commercial buildings, with 80-mil specified on hail-prone or high-traffic applications. 50-mil is the budget option for protected applications. We don't typically recommend the thinnest options for Denver applications.

  • Does PVC roofing qualify for ENERGY STAR or cool-roof rebates?+

    Most major manufacturers' white PVC membranes carry ENERGY STAR ratings and meet cool-roof code requirements. Specific rebates and tax incentives vary by program, year, and jurisdiction, talk to your tax advisor or local utility about what's currently available.

  • Can PVC be installed over my existing roof?

    In some cases, yes, but compatibility considerations are particularly important on PVC. PVC is incompatible with asphalt-based substrates and some other materials, requiring proper separator sheets or substrate preparation. On many recover applications, our inspection determines whether PVC is suitable or whether a different system or full tear-off makes more sense.

Frequently Asked Questions: Commercial Single-Ply Membrane Roofing in Denver

  • What is the most common commercial single-ply membrane in Denver?+

    TPO is currently the most-installed new commercial single-ply membrane system in Denver and nationally. EPDM remains common on re-roof projects matching existing systems and on applications where its specific advantages matter. PVC dominates the restaurant, food service, and chemical-exposure category but is less common on general commercial buildings.

  • How long does a commercial single-ply membrane roof last?+

    Manufacturer warranties on commercial single-ply systems typically run 15 to 30 years, depending on system, membrane thickness, and warranty type. Real-world service life often meets or exceeds the warranty period when installation is done properly. Hail and severe weather events can shorten any single-ply roof's service life.

  • Are all single-ply membranes good for cool-roof performance?+

    White single-ply systems, white TPO, white PVC, and white EPDM (or coated EPDM), all deliver strong cool-roof performance and qualify for ENERGY STAR ratings on most major manufacturer products. Standard black EPDM is not a cool roof. The cool-roof decision is driven by membrane color and surface, not by chemistry alone.

  • How much does single-ply membrane roofing cost in Denver?+

    Cost varies by system, thickness, installation method, building size, and substrate condition. EPDM is typically the lowest-cost material; TPO is moderately priced and very common on new installations; PVC is the highest cost. Installation method (mechanically-fastened vs fully-adhered vs ballasted vs induction-welded) significantly affects total project cost. We provide written estimates after inspecting the actual roof.

  • Can a single-ply membrane be installed over my existing commercial roof?+

    In some cases, yes, single-ply systems can be installed as recovers over certain existing substrates when the existing roof is structurally sound and code allows it. Each substrate has compatibility considerations, particularly for PVC. Our inspection will tell you whether recover is appropriate for your building or whether tear-off and re-roofing makes more sense.

  • How does hail affect single-ply membrane roofs in Denver?+

    All three single-plies can be damaged by severe hail, and the damage profile differs by system: TPO and PVC tend to show fractures and punctures at impact sites; EPDM tends to show bruising and elastic-deformation damage. Thicker membranes (60-mil and 80/90-mil options) handle hail substantially better than the thinnest options. Impact-rated and reinforced products improve hail performance further. We strongly recommend not specifying the thinnest membrane options on Denver buildings.

  • Do all single-ply systems require manufacturer-certified installers?

    Most manufacturer warranty programs require installation by certified contractors to remain valid. Each major manufacturer maintains its own certification program for installer training and quality control. Baseline holds certifications across all major commercial single-ply manufacturers for TPO, EPDM, and PVC systems.

Frequently Asked Questions: Commercial Modified Bitumen Roofing in Denver

  • How long does a modified bitumen roof last?+

    Manufacturer warranties on commercial modified bitumen systems typically run 15 to 20 years on standard installations and up to 30 years on premium multi-ply systems. Real-world service life on properly installed mod-bit commonly meets or exceeds the warranty, with well-maintained systems delivering 25 to 30+ years before replacement is needed.

  • How much does modified bitumen roofing cost in Denver?+

    Mod-bit cost depends on application method, number of plies, modifier chemistry, granular cap sheet selection, and project size. Per square foot, mod-bit is typically priced between EPDM and PVC, often comparable to TPO depending on specifications. Self-adhered installations are typically the most expensive; torch-applied and hot-mopped are typically lower-cost depending on project access and crew availability.

  • Modified bitumen vs. TPO: which is better?+

    It depends on the application. TPO is typically the better choice for general commercial buildings with priority on cool-roof reflectivity and competitive cost. Modified bitumen is typically the better choice for buildings with heavy foot traffic, applications where multi-ply redundancy matters, hail-prone exposure where impact resistance matters, and re-roof projects over existing asphalt-based systems. Our inspection and the building's specific use will tell us which fits better.

  • Should I choose SBS or APP modified bitumen for my Denver building?+

    For most Denver commercial applications, SBS-modified bitumen is the better fit. SBS handles Denver's cold winters and temperature swings substantially better than APP. APP can be appropriate on specific applications with heavy solar exposure where the harder, more plastic-like membrane offers advantages, but SBS is the default for the Denver market.

  • Is torch-down installation safe for my building?+

    With professional execution, yes. Torch-down requires hot-work permits, fire watch protocols, and proper torch technique, all standard parts of professional commercial torch-down work. For occupied buildings, hospitals, schools, and projects where fire safety has elevated importance, cold-applied or self-adhered modified bitumen eliminates the torch-down fire concerns entirely. We'll recommend the application method that fits your specific project.

  • Does modified bitumen qualify for ENERGY STAR or cool-roof rebates?+

    Modified bitumen with white granular cap sheets carries ENERGY STAR ratings on most major manufacturer products and meets cool-roof code requirements where applicable. Specific rebates and tax incentives vary by program, year, and jurisdiction, talk to your tax advisor or local utility about what's currently available.

  • Can modified bitumen be installed over my existing commercial roof?

    In some cases, yes. Mod-bit can be installed as a recover system over existing built-up, modified bitumen, or certain other substrates when the existing system is sound and code allows it. Recover applications are often particularly attractive on older commercial buildings with existing asphalt-based roofs because chemistry compatibility is straightforward. Our inspection will tell you whether recover fits your building or whether tear-off and replacement makes more sense.

Frequently Asked Questions: Commercial Built-Up Tar & Gravel Roofing in Denver

  • How long does a built-up roof last?+

    Manufacturer warranties on commercial BUR systems typically run 20 to 30 years. Real-world service life on properly installed and maintained BUR commonly exceeds the warranty significantly, 30 to 40+ year service is well-documented, with some systems delivering 50+ years. BUR has the longest proven track record of any commercial roof system.

  • How much does built-up roofing cost in Denver?+

    BUR cost depends on the number of plies, asphalt type (asphalt vs. coal tar), surface configuration (gravel vs. cap sheet), and application method (hot-applied vs. cold-applied). Per square foot, traditional hot-applied gravel BUR is typically priced higher than equivalent single-ply or modified bitumen due to labor intensity. Total project economics vary widely based on building specifics.

  • BUR vs. modified bitumen: which is better?+

    It depends on the application. Modified bitumen offers faster installation, lower weight, and competitive cost, making it the better choice for most new commercial work in Denver. BUR offers stronger hail and impact resistance through its gravel surface, longer track record, and stronger fire resistance, making it the better choice for hail-exposed buildings, institutional applications, and re-roof projects over existing BUR. Our inspection and the building's specific use will tell us which fits better.

  • Is the gravel surface really better for hail than other systems?+

    Yes, meaningfully. The loose gravel ballast absorbs and disperses hail energy before it reaches the underlying membrane plies. On Front Range buildings with significant hail exposure, BUR's hail performance materially exceeds membrane systems. This is one of the strongest practical arguments for BUR on Denver commercial buildings.

  • Can BUR be installed in cold weather in Denver?+

    Hot-applied BUR has limited cold-weather installation windows because the asphalt requires adequate substrate temperatures for proper cure. Cold-applied BUR uses asphalt-based emulsion adhesives that extend the installation season, at additional cost. Most BUR projects in Denver are scheduled for warmer months.

  • How is hail damage repaired on a BUR roof?+

    Localized hail damage on BUR is typically repaired by carefully removing gravel around the affected area, exposing and repairing damaged plies with new asphalt and reinforcement, and re-distributing or replacing the gravel surface. The gravel-surface inspection challenge can make leak diagnosis more complex than on smooth-surfaced systems, but the multi-ply redundancy means a single damaged area rarely compromises the entire roof.

  • Is BUR a cool-roof system?

    Standard gravel-surfaced BUR is not a cool roof, gravel surfaces have low solar reflectance and high heat absorption. White gravel BUR and reflective-coated BUR systems can deliver some cool-roof performance, but typically not at the level of white single-ply or white granular modified bitumen. For cool-roof-priority projects, BUR is rarely the right system.
