SPF roofing

Insulation, drainage and UV protection for low-slope roofs.

Spray polyurethane foam (SPF) combines continuous insulation with a seamless roof surface. A reflective protective coating shields the foam from desert sun. We assess the deck, drainage and roof details before specifying the assembly.

Continuous insulation

Foam forms a continuous layer that helps limit heat transfer. The required thickness depends on the building and proposed roof assembly.
Drainage and details

Slope, scuppers, equipment curbs and penetrations are assessed together. Foam thickness can help shape drainage where the roof design allows.
Renewable UV protection

The coating protects the foam from sunlight and weather. Inspecting and renewing it while the foam remains sound can extend the service of the roof.

SPF roofing questions.

What is SPF roofing?

SPF stands for spray polyurethane foam. The foam creates continuous insulation and a seamless roof surface, with a protective coating shielding it from sunlight and weather. The roof deck, drainage and details need assessment before the assembly is specified.

Is SPF an option for a low-slope roof?

SPF can be an option for low-slope residential and commercial roofs. Suitability depends on the existing roof condition, substrate, drainage and proposed assembly. Equipment curbs, scuppers and penetrations must be considered with the roof surface.

Does an SPF roof need maintenance?

Yes. The protective coating needs inspection and renewal as it wears. Exposed foam, damaged details and drainage problems should be assessed before deciding whether the roof needs localized work, recoating or replacement.
