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 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 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
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.

Greeley Roofing Questions
What roof system works over a food processing plant?
Food plants run wet, cold, and around the clock, and they often exhaust fats and oils that attack some membranes. PVC resists those residues better than TPO or EPDM. High interior humidity also means the vapor retarder matters, so moisture does not condense inside the roof assembly. We plan work around sanitation and production schedules with plant engineering.
Can you roof a cold storage or freezer building?
Yes. Cold storage roofs reverse the usual vapor drive, so the vapor retarder and insulation layout need careful design to keep moisture out of the assembly. Thick insulation and well-sealed penetrations prevent ice buildup and energy loss. Work over active freezers is sequenced so the building stays sealed and product stays at temperature.
How do open-plains winds affect our Greeley roof design?
Open terrain lets wind reach buildings with little to slow it down. Wind design in the adopted building code accounts for that with a higher exposure category, which raises design pressures at corners and edges. Strong edge metal, tighter perimeter fastening, and secured rooftop equipment do most of the work in keeping the roof attached.
Is emergency roof repair available in Greeley?
Yes. Greeley is part of our Colorado Emergency Roof Repair coverage. For a food plant or warehouse, a leak can halt production or ruin inventory, so the first job is to stop the water and protect the space below. We then photograph the damage and lay out the permanent repair. Call 720-753-4836.
