Spray Foam Roof Coating
Spray foam roof coating utilizes Spray Polyurethane Foam (SPF) to create a waterproof, ultra-insulated roof barrier. This is a great method for improving your roof without replacing it entirely. At Schwartz Commercial Roofing, we can apply a spray foam roofing system to your roof to improve its strength and longevity while protecting it against the elements.
Unlike other roof restoration methods, spray foam insulates your roof and can save energy costs when it comes to both heating and cooling your building. This is a great choice for metal, concrete, wood, and many other roof materials. Spray foam roof systems are backed by a warranty of up to 20 years. As with other roof restorations, this can be expensed as a repair or maintenance cost in most cases. A full roof replacement, on the other hand, cannot.
Waterproof protection—a spray foam barrier renders your roof waterproof and increases insulation, allowing it to withstand the elements. Closed-cell foam increases the strength of your roof overall while reducing expansion and contraction.
Heat-resistant barrier—the reflective nature of this barrier keeps your roof safe from heat stress and your energy costs low. Your building will stay warmer in the winter and cooler in the summer.
Lightweight durability—our spray foam roof barriers are lightweight and will not burden your roof like other options possibly can.

Our Spray Foam Process
From prep and clean to foam application and protective topcoat—we deliver a seamless, waterproof, insulated roof without full replacement.
Prepare the Roof
We prepare the roof by cleaning up all dirt and debris so the spray foam can bond properly to the surface.
Apply Spray Foam
We combine the ingredients to create the spray foam and apply it to the roof. The foam expands to create a seamless, lightweight layer that penetrates your roof's pores.
Seamless Barrier
The coating can be applied to most roof systems. At about eight ounces per square foot, the lightweight foam does not exceed the structural load capacity for most roofs.
Protective Topcoat
We finish with a UV-resistant topcoat where specified, protecting against weathering and extending the roof's lifespan. Systems are backed by warranty of up to 20 years.

Billy came and did a roof for me and it turned out fantastic. I appreciated him coming when he said he would and doing what he said he'd do. That's hard to find in a contractor in today's world. He has now done 3 roofs for me and I wouldn't go anywhere else.
