Polyurethane foam roof systems are a spray-in-place insulation made of rigid, closed-cell Spray Polyurethane Foam (SPF). This fully adhered, self-flashing system is seamless and seals all penetrations with no joints, fasteners, or seams. SPF can be sprayed in place in a way that builds up slope to enhance drainage and minimizes ponding water. SPF provides increased insulation value and seals all openings providing a, truly, monolithic surface. The highly reflective white finish will provide maximum solar reflectance and energy savings. Excellent for second roofs over metal and built up roofs while also remaining an option if the existing roof needs to be torn off.
