Commercial Roofing in Boulder

Boulder’s Trusted Commercial Roofing Contractor

Strong Contractors serves Boulder County’s commercial, tech, and institutional facilities with self-performed roofing and building envelope systems. High-altitude UV, heavy hail, and rapid foothill weather shifts define Boulder’s roofing demands. Every system we specify accounts for these Front Range foothill conditions.

Full-Scope Capabilities for Boulder Facilities

Every service is self-performed by our crews — no subcontractors, no middlemen. Each system is specified for Boulder’s altitude, hail, and wind environment.

Ballast Removal in Boulder

Removing ballast is often the first step in a Boulder energy retrofit, since insulation cannot be added or the membrane replaced while the stone is still in place. It also takes a heavy load off the deck. We plan the removal around occupied labs, offices, and campus buildings and haul the stone away.

Emergency Roof Repair in Boulder

When a windstorm peels back roofing or hail punctures a membrane in Boulder, water can reach labs, server rooms, and classrooms. Colorado-based crews from Strong Contractors respond to that kind of storm damage and to active leaks, installing a temporary dry-in over sensitive equipment. We document the damage so engineers and insurers can plan the permanent repair.

EPDM Roofing in Boulder

Boulder is known for severe downslope windstorms off the foothills in winter, and loose or poorly secured roofing is the first thing to fail. A fully adhered EPDM system with properly fastened perimeters resists that uplift and stays flexible in the cold. It suits the many low-slope buildings on Boulder's research and tech campuses.

Polyurethane Coatings in Boulder

Polyurethane coatings form a durable, flexible membrane over spray foam, concrete, and metal. Boulder's foothills location brings intense sun, big temperature swings, and wind-driven grit, and a polyurethane system resists that abrasion while moving with the substrate. It fits rooftop mechanical areas, walkways, and protective coatings on research and campus buildings.

Silicone Roof Coatings in Boulder

A silicone roof coating restores an aging roof in place, keeping tear-off debris out of landfills and dust away from occupied labs and classrooms. It renews waterproofing over sound membrane and metal roofs in Boulder. A moisture survey comes first, since a coating only works over dry insulation.

TPO Roofing in Boulder

Boulder holds commercial buildings to its own energy code and building performance goals, and roofing work has to fit them. A reflective TPO membrane over upgraded insulation helps research, office, and university buildings meet those targets. We provide as-built documentation so engineers and facility teams can confirm what was installed.

Commercial & Industrial Roofing

Commercial & Industrial Roofing

A commercial roof is a major building asset, and the right solution depends on more than the system that is already in place. Condition, moisture, drainage, insulation, facility operations, budget, warranty requirements, and long-term plans for the property all influence whether repair, restoration, retrofit, or replacement provides the best value.

Strong Contractors brings experience across virtually every major commercial roofing system, along with waterproofing, coatings, spray polyurethane foam, restoration, repair, and specialized services. That breadth allows us to execute projects designed to established plans and specifications or work with owners, engineers, and consultants to evaluate options and determine the most practical path forward for the facility.

Fluid Applied Roof Systems

Fluid Applied Roof Systems

Fluid-applied roofing systems can be an effective way to restore and extend the service life of an existing roof without automatically moving to a full tear-off and replacement. When the existing assembly is a suitable candidate, these systems can address difficult transitions, penetrations, drainage conditions, and irregular roof geometry while creating a seamless, fully adhered protective surface.

Strong Contractors is an SPFA Accredited Contractor with extensive training and experience in spray polyurethane foam (SPF) and fluid-applied roofing systems. These systems depend heavily on proper substrate preparation, application thickness, detailing, environmental conditions, and quality control, which makes contractor experience and technical training especially important to long-term performance.

Industrial Coatings

Industrial Coatings

Industrial coating systems help protect concrete, steel, and other substrates exposed to moisture, corrosion, chemicals, abrasion, and demanding operating conditions. These systems are commonly used on tanks, containment areas, concrete surfaces, structural components, and other specialized areas where durability and long-term protection are critical.

Selecting the right coating depends on the substrate, existing surface condition, service environment, chemical exposure, and expected performance of the finished system. Strong Contractors installs protective coating systems for commercial and industrial facilities, with careful attention to surface preparation, application conditions, product compatibility, and quality control—factors that directly affect adhesion, durability, and long-term performance.

Specialized Services

Specialized Services

For Colorado facilities, Strong Contractors provides emergency roof repair and ongoing maintenance plans to address active issues, reduce recurring problems, and help owners stay ahead of larger roofing failures. Strategic repairs and maintenance can extend the useful life of an existing roof, help bridge the time until a larger capital project is planned, and support manufacturer warranty requirements where ongoing maintenance is required.

Strong Contractors also provides specialized building-envelope services, including air and vapor barrier systems and below-grade waterproofing. Our experience includes large-scale industrial and complex new-construction scopes where sequencing, access, detailing, and coordination are critical.

Local FAQ

Boulder Roofing Questions

Straight answers to what Boulder owners and facility managers ask us most.
Let's Discuss Your Project

How do you keep a roof attached during a Boulder windstorm?

Boulder’s downslope winds put heavy uplift on corners, perimeters, and edge metal. We design securement to the wind loads in the adopted building code and favor fully adhered membranes, tighter edge fastening, and tested edge systems on exposed buildings. Loose rooftop items like pavers, ballast, and equipment covers also get secured or removed.

Can ballast be removed from an older Boulder roof?

Yes. Loose ballast can scour and move in high winds, and its weight hides membrane problems. We remove the ballast, inspect the membrane and insulation, and convert the roof to an adhered or mechanically attached system. Removal also opens up options for a reflective membrane or a coating, depending on the condition of what is underneath.

Does Boulder's energy code affect a roof replacement?

It can. Boulder adopts its own energy code amendments, and a reroof there can bring insulation requirements that change tapered layouts, curb heights, and edge details. We check current requirements with the city during design so the scope and price reflect them. Added insulation also supports the energy goals many Boulder owners already track.

How do you work on occupied federal or university research buildings in Boulder?

Research buildings often run sensitive instruments, controlled air, and strict access rules. Each person on the crew is background-checked and can be badged for the site. We set access, staging, and hours with the facility team, protect air intakes from fumes and dust, and photograph each detail for compliance review. Work is sequenced around the building’s research schedule.
