Sprayed Polyurethane Foam (SPF) Roofing Systems

What is SPF?

The SPF roofing system is composed of two chemical compounds called isocyanate and polyol. This system excels in roof-over applications and is an excellent choice in roof systems for buildings with wind uplift concerns.

SPF Application

After removing all debris from the existing substrate or roof, the isocyanate and polyol are mixed together in a 2:1 ratio, and then sprayed onto the surface. It dries to a seamless finish. A UV protective coating best suiting the needs of that particular roof is then applied to the dried foam. Common coatings include acrylic, silicone, and urethane. If a roof requires resistance to wear due to foot traffic, a cementitious coating can be applied over the sprayed foam. Slip-resistant granules are also broadcasted into the coating.

SPF roof systems can be customized to fit particular drainage requirements. Adequate drainage is particularly important in these systems because of their natural sensitivity to water. Uneven application of the foam creates opportunities for small puddles to form on the roof. The stagnant water can decrease the life of the system’s coating.
