Spray Foam Roofing SPF Roofing Systems provide many benefits to building owners. The two most prominent benefits are waterproofing/leak prevention and insulation value. Many additional benefits also exist such as superior compressive strength, lightweight, self-flashing, durable and long lasting. SPF is a closed-cell roofing material formed by combining two liquid components. When these two materials meet in the mixing gun, they expand 20 to 30 times their volume immediately, forming rigid polyurethane foam (PUF). This foam is sprayed on the entire roof to the desired thickness, usually 1-2 inches, to form a seamless monolithic surface including flashing, penetrations and parapet walls. This eliminates seams and cold joints, the primary source of major leaks, and provides a durable waterproof covering that bonds tightly to nearly any properly prepared surface. Seamless: Seams are one of the major sources of leaks in roof systems and SPF roofs are totally seamless. Polyurethane foam is applied as a liquid, creating a single monolithic membrane that covers the entire roof – no seams and no joints. The foam is easy to replace when stacks or other roof penetrations need to be moved or added. Lightweight: Foam roofing typically weighs around 50 lbs per square, versus 800 lbs for a built-up roof and 1000 lbs. for ballasted single-ply roofs. This reduces the structural dead load on your roof.
