For a flat or commercial roof, there is no better roofing solution than a spray polyurethane foam roofing system. Roofing spray foam conforms to the roof surface with a strong bond that provides a seamless monolithic system and contains no thermal shorts. It provides a greater insulation factor with an R-value of 6.3 per inch, an unsurpassed air-barrier, increased structural stability, and requires less time to install. A spray foam roofing system has an effective lifespan that can exceed 30 years and has the lowest lifecycle cost over other conventional roofing systems.
