Polyurethane Foam Roof

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

When foam is visible, apply a protective 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 Foam Roof Maintenance

Sprayed polyurethane foam should be inspected annually and recoated every 10 years.

Polyurethane Foam Roof Coating

Water Based System

Our EnergyGuard® Acrylic Elastomeric Coating is frequently installed on polyurethane foam during the initial installation stage or as a maintenance recoat.

Solvent Based System

Our EnergyGuard® Silicone Elastomeric Coating provides a protective topcoat with excellent weathering over polyurethane foam. It should be used to recoat silicone-coated polyurethane foam roofs.

What is Polyurethane 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.
