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.

Castle Rock Roofing Questions
How do you reroof a multi-tenant outlet or retail center?
Shared roofs over many tenants need a phased plan. We break the roof into sections by tenant or building, coordinate with property management on store hours and deliveries, and close each section to the weather at the end of every shift. Rooftop units and penetrations above every tenant get flashed and photographed, giving the landlord a record organized by space.
Can you work on public buildings and schools in Castle Rock?
Yes. Public and education projects usually come with formal bidding, fixed scheduling windows, and documentation requirements. We plan around school calendars and public operating hours. Closeout includes weld test results, detail photos, and as-built drawings that facility staff and reviewers can file. Education, institutional, and government buildings are all part of our commercial focus.
Which roof system handles Castle Rock's snow and UV together?
The system has to resist UV aging in summer and carry snow and ice in winter. Reinforced TPO, PVC, and EPDM all perform well when the details are right. Drainage matters as much as the membrane, because snowmelt that ponds and refreezes stresses seams. Crickets, sumps, and enough slope toward each drain keep meltwater moving off the roof.
Is Castle Rock covered by your emergency roof repair service?
Yes. Castle Rock is close to our Parker headquarters, and our Emergency Roof Repair service covers all of Colorado. Crews put a temporary weather seal in place, protect the contents below, and record conditions with photos for your insurer and the long-term fix. Call 720-753-4836.
