Professional Commercial Roof Installation & Replacement

When searching for a commercial roofing contractor, property managers and facility owners should require proof of capability, safety, and strict compliance. At Custom Exteriors, we recognize that a major roof installation is a significant capital investment that demands transparent budget forecasting, proper insurance credentials, and a clear timeline to avoid business interruption. As a proud member of the Colorado Roofing Association (CRA) serving the Front Range since 2018, we provide the technical knowledge, drone-assisted inspections, and full-trade capabilities required to complete large-scale commercial projects on schedule and within budget.

Commercial Roofing Systems We Specialize In:

Thermoplastic Polyolefin (TPO) single-ply membranes are the top choice for modern flat roofs due to their high solar reflectivity and energy efficiency. Our certified teams install heat-welded TPO systems that lower cooling costs and offer excellent puncture resistance against severe Front Range hail.

Ethylene Propylene Diene Monomer (EPDM) synthetic rubber provides exceptional durability for industrial properties and warehouses. It naturally expands and contracts during extreme temperature swings without cracking, offering a time-tested, cost-effective defense against heavy weather.

Standing-seam metal roofing delivers premium longevity and a modern architectural aesthetic. Utilizing concealed fasteners to drastically reduce water penetration risks, these systems easily handle fire, wind, and heavy snow loads with minimal maintenance.

Modified Bitumen roofing uses a multi-ply asphalt approach, making it perfect for high-traffic commercial roofs that house heavy HVAC units. It offers outstanding tensile strength, robust puncture resistance, and seamless waterproofing at critical drains and transitions.

If your roof structure is sound, a fluid-applied silicone or acrylic coating restores your asset without the expense of a full tear-off. This seamless, elastomeric layer stops minor leaks and extends the service life of your flat roof by a decade or more.

Commercial Roof Replacement

Comprehensive Commercial Roofing

Every commercial property has unique structural needs, architectural slopes, and operational demands. Whether you manage a large retail strip mall, a sprawling warehouse, or a multi-story hotel, we provide comprehensive roofing services tailored to your building. From low-slope standing seam metal roofs to traditional asphalt multi-ply systems, our certified crews handle all commercial roofing styles with top-tier materials engineered to withstand tough Colorado hail and wind.

Roof Coatings

Proactive Roof Coatings

You do not always have to pay for a costly, messy tear-off to fix a failing roof. If your roof structure is still dry and solid, we can apply a high-performance fluid-applied silicone or acrylic coating directly over the top. This liquid layer rolls on like thick paint, dries into a seamless rubber coating, seals up all minor leaks, and bounces away hot sun rays to lower your cooling bills. It extends your roof’s life by 10 to 20 years for a fraction of the cost of a new roof.

Flat Roofing

Commercial Flat Roof Replacements

If your flat roof is leaking, waterlogged, or past its useable lifespan, a full roof replacement may be the best way to secure your building. We specialize in installing modern single-ply membranes like TPO (heat-welded plastic) and EPDM (heavy-duty rubber). Our team handles the entire process, including tearing away old materials, replacing damaged insulation boards, and sealing all critical seams to create a completely watertight shield over your business.

Commercial Roof Repair

Preventative Maintenance & Repair

Small leaks can quickly turn into massive, expensive structural problems if they are ignored. Our repair teams are experts at tracking down tricky commercial leaks and fixing them fast. We handle everything from patching punctures in rubber membranes to sealing cracked flashing around HVAC units, pipes, and roof drains. We also offer simple, proactive preventative maintenance plans to clear out debris and catch small issues before they cause costly interior damage.

Commercial Exterior Services: Beyond the Roof

Complete Exterior Capabilities

Commercial property managers and business owners need a reliable partner who can manage the entire exterior envelope. At Custom Exteriors, we streamline complex restoration and capital improvement projects by coordinating all your major exterior trades with a single partner. Our single-source approach reduces project downtime, simplifies job site logistics, and gives you one point of contact for complete quality control across your entire property.

Commercial Siding & Cladding

We install high-performance fiber cement, engineered wood, metal panels, and masonry accents designed for high-traffic commercial environments. Our siding systems improve thermal efficiency, meet strict fire codes, and upgrade your building's professional curb appeal.

Commercial Windows & Glazing

Our team handles commercial-grade replacement windows engineered for energy efficiency, noise reduction, and structural strength. Precision installation ensures tight thermal seals that lower operating costs and enhance interior comfort for tenants and employees.

Exterior commercial painting

We apply top-tier Sherwin-Williams paints to protect your building’s exterior from high-altitude UV rays, harsh weather, and everyday wear. Our process includes extensive surface preparation, power washing, caulking, and detailed application to create a durable exterior for your property.

Commercial Gutters, Downspouts & Drains

Proper water management is essential to protect your foundation, walkways, and parking areas. We custom-fabricate heavy-gauge, high-capacity seamless aluminum gutters and commercial downspouts built to handle heavy snowmelt and rapid mountain storm run-off.
