Sprayed Polyurethane Foam must be protected by elastomeric coatings to prevent ultraviolet-induced surface degradation.

When foam is visible, apply a roof coating without delay!

Common Issues


UV Degradation - A majority of SPF failures occur because of the loss or erosion of the protective elastomeric coating.	Interlaminar Blisters - These are usually caused by installer error or equipment problems. Blisters must be removed and area must be re-foamed.	Wet Foam - When the protective coating is broken, moisture infiltration can accelerate deterioration. Wet foam should be removed and new foam installed.

Polyurethane Spray Foam

Sprayed Polyurethane Foam deteriorates quickly when exposed to the sun’s UV-rays. It needs to be coated with a UV protective coating immediately!

Polyurethane spray foam should be inspected annually and recoated every 10 years.

Polyurethane Spray Foam Roof Coating & Restoration

Add 10 or more years to your polyurethane foam roof with our polyurethane foam roof restoration system. Get a seamless roof without costly tear off and disruption. Stop roof leaks and prevent further degradation.

EnergyGuard® Acrylic Elastomeric Coating may be used on sprayed polyurethane foam roofs during the initial installation stage or as a maintenance recoat. Acrylic elastomeric coatings cannot be used to recoat silicone-coated roofs.
EnergyGuard® Butyl Elastomeric Coating may be used on sprayed polyurethane foam roofs when the application requires a vapor barrier. Prevents moisture build up in polyurethane spray foam when used in cold storage applications.
EnergyGuard® Silicone Elastomeric Coating may be used on sprayed polyurethane foam roofs to achieve a protective topcoat with excellent weathering properties. It should be used to recoat silicone-coated polyurethane foam roofs.

What is Polyurethane Spray Foam?

Polyurethane foam is an insulating foam material often used on rooftops.

Two liquid components are combined and sprayed onto a surface to form SPF. The components react and harden to form a rigid, waterproof insulating layer.

Polyurethane foam is self flashing and is the roofing material of choice for fixing ponding water problems on nearly-flat or flat roofs.

Reflectivity of Polyurethane Foam Roofs

The solar reflectivity of Polyurethane Foam Roofs depends on the color of the finish coat.

Polyurethane foam has excellent insulating properties. Elastomeric coatings improves the thermal efficiency by reflecting the sun's heat . It is a required topcoat for SPF systems. White roof coatings can reflect up to 90% of the heat from the sun.
