The foam is professionally applied with a spray gun that mixes two liquid components to form a rigid polyurethane foam (PUF).
It’s so lightweight - about eight ounces per square foot - it can be applied over most existing roof systems without exceeding the structural load capacity.
Yet it is amazingly strong, easily withstanding foot traffic and other weight requirements. SPF roofs keep saving you money by reducing tear off cost, keeping hot air out and warm air in the building in the winter. The seamless system reduces the need for repairs, and unlike some systems, recoats with ease, extending the life of the roof.
