Why are foam roofs energy efficient?
Foam is more energy efficient than any other flat or low slope roof system. The reflective surface coating is classified as a Cool Roof System and is certified by Energy Star for its efficiency. Foam is also extremely energy efficient because of the insulation properties of polyurethane foam. The polyurethane foam applied on our roof systems has no joints for heat to escape (unlike foam board insulation installed in 4’x8′ sheets on other roof systems). In addition, the placement of the foam roof system on the outer most surface of the roof structure improves energy efficiency by keeping the underlying mass of roof structure at a stable and comfortable indoor air temperature. With other roof systems, the roof surface heats up and cools down with outside air temperature working negatively against the desired indoor temperature. For example, a tar and gravel or cap sheet roof typically reaches temperatures around 160ยบ F on a warm summer afternoon. This hot mass of material transmits a lot
