SPRAYED POLYURETHANE FOAM (SPF): Spray foam roofing starts out as two liquid components - an isocyanate, known as the "A" component, and a resin (or polyol), the "B" component. When the liquids are mixed at a one-to-one ratio, a chemical reaction occurs and the mixture expands 20 or 30 times forming a solid, monolithic (seamless), closed-cell, fully-adhered roof system that provides excellent water-resistance and thermal insulating abilities.

SPF adheres to just about everything so it can be installed over concrete, wood, steel, and most existing roof systems (EXCEPT APP MODIFIED BITUMEN!) which saves on the expense of roof removal and landfill fees. SPF mechanics can spray apply a tapered roof system with the foam which eliminates the need for costly tapered insulation systems. The cants and vertical wall terminations are also spray applied making them an integral part of the roof system and minimizing additional component costs.
