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.

Lone Tree Roofing Questions
How do you replace a roof over a large shopping mall?
Mall roofs cover huge areas with skylights, food court exhausts, and dozens of rooftop units over different tenants. We phase work by zone, schedule disruptive tasks outside shopping hours where possible, and keep public entrances clear of staging. Grease exhaust areas often get PVC or added protection, since restaurant residue attacks many membranes.
How do we keep a new office roof under warranty for its full term?
Manufacturer warranties often require periodic inspections, prompt repair of damage, and certified installers for any roof work. Keep records of every inspection and repair, and do not let other trades cut into the membrane without a certified roofer present. We are certified by Carlisle, Firestone, GAF, and Tremco, so we can handle warranty repairs and keep the documentation complete.
Should we inspect our roof after a heavy spring snowstorm?
Yes, especially after heavy, wet spring snow. Look for ponding where drains froze, sagging near rooftop units, and damage left by snow removal. Check interior ceilings under drift areas along taller walls. Metal shovels often cut membranes, so any rooftop clearing should be supervised or done by a roofing crew.
How do you protect a server room during a roof replacement?
Server rooms and IT closets need protection from water, dust, and power interruptions. We identify those spaces before work starts, add temporary protection above them, and schedule tear-off over them for dry days, with the roof sealed each night. Any rooftop cooling equipment serving them is coordinated with IT and facilities teams to avoid unplanned downtime.
