Roofing Systems

Advanced Polyurethane Foam

A sprayed in-place polyurethane roof actually consists of "three roofs" of protection: First, a layer of closed cell seamless monolithic blanket of polyurethane foam insulation (which is the same type of material used in marine flotation). Due to its closed cell nature water will not travel laterally or migrate through it. Leaks, therefore, are easily located and easily repaired. The second layer consists of a durable, yet flexible base coat of GE Silicone roof coating that protects water from ever reaching the polyurethane foam. The third line of defense is a top coat consisting of another layer of GE silicon to guarantee water resistance. The final layer of the roofing system consists of granules that are embedded in the top coat for UV protection.

Water just can't penetrate the roofs structure. Period.

Important Characteristics of Polyurethane Foam

Sprayed on Polyurethane Foam forms a "seamless" insulated roofing system. It has no joints or seams that often allow outside water and air to pass through the roofing system into the structure. Another excellent characteristic of the Polyfoam system is how little it weighs. One inch thickness of polyfoam with 30 mils of elastomeric coating weights about 1/2 lb. Compare that to 6-13 lbs. per square foot for a typical, conventional four ply built-up roofing system.

This makes a sprayed Polyurethane Foam system ideal for retrofitting, especially when applying it over an existing built-up roof without removing it.

Quote from Ford Motor Company

"The Spray Polyfoam roof stopped all leaks and reduced our energy bill by an average of $464,000 per year on this million square foot re-roof."
