Spray Polyurethane Foam (SPF) is a liquid that is sprayed through specialized mixing equipment on to the existing roof, and within seconds expands into a hard lightweight seamless foam. This creates a solid layer across an existing roof adhering onto the roof surface and sealing the dwelling.  After the foam roof is applied, it is then covered with a layer of acrylic, elastomeric, or silicone roof coating - creating a seamless roofing system. SPF Technology produces a long-lasting roofing system. SPF has been in existence for decades and is still widely used today on residential roofs, commercial roofs, and mobile homes. SPF is considered a California Cool Roof system and is Title 24 compliant. Spray Polyurethane Foam Roofing is in high demand for its cool roof properties, low-weight roof system, and seamless application. When applied by an experienced roofing contractor and properly maintained a SPF roof can last for decades. Daniels Roofing is a spray foam and roof coating specialist.
