A polyurethane spray foam roofing system—often referred to as an SPF roofing system—is an excellent solution for flat and low-slope commercial roofs, either as an original roofing material or in restoration applications.
If your existing roof is leaking or experiencing other age-related problems, you’ll want to seriously consider SPF roofing for its flexibility and longevity. Spray polyurethane foam is also one of the only roofing materials that can add insulation value to your roof.
