Sprayed Polyurethane Foam, also known in the roofing industry as SPF, has been used as a roofing material for over 50 years. Sprayed Polyurethane Foam is applied as a liquid using plural-component spray equipment. The sprayed-on SPF liquid expands approximately 25 times its original volume to form a hard, closed cell, monolithic insulation and roof surface.

The Polyurethane Foam cures or dries within seconds after being applied to the roof surface. Its expansion results in a weather tight roofing membrane that is fully adhered to the roofing substrate. A protective elastomer – either urethane or silicone - top coat is then applied over the foam. This protective top coat can be sprayed on, or applied with hand or power rollers.

Spray foam roofing systems have many advantages over traditional roofing methods.

The foam roofs are seamless, applied as a liquid and flows into crevices, and bonds together, creating a single monolithic membrane that covers the entire roof.

Spray foam is easily applied. The foam can be sprayed onto virtually any clean surface. Irregular, or odd shaped roofs and protrusions can be easily covered.

Lightweight and high strength. Foam roofing systems generally weigh approximately 5 lbs. per square foot. This is 50% less weight than a traditional built-up roof that can weight 10 lbs. per square foot or more.

High insulation value. Sprayed polyurethane foam has a thermal resistance, R-value rating of up to 7.14 per 1 inch thickness. SPF roofs can provide more thermal resistance with less material than any other type of roofing insulation, up to 25% greater than alternative insulation and roofing systems.

As with all roofing systems, the SFP roof system has to be installed to the manufacturers installation instructions, the listing, where applicable, and the building code.
