Sprayed Polyurethane Foam (SPF) Roofing

Installing Sprayed Polyurethane Foam (SPF) roofing system on a new building, or retrofitting your older roof with an SPF roof can save you money in a lot of different ways. Most of the causes of additional roofing expenses don't exist when you have a foam roof system.

Foam Roofs have no seams to split or pull apart and allow water to enter. Foam is ideal for saw tooth or other irregular roof shapes that are difficult or impractical for old fashioned low-tech roofing materials.

Sprayed Polyurethane Foam is also the best insulator on the market. Very little maintenance or repair is ever needed, and with proper care, it is the last roof you will ever need to buy.

Foam Density and R-Value

 

Density of SPF is important when it comes to strength and Thermal Resistance. Obviously, higher density means increased strength and higher R-value. Most SPF roofs have densities ranging from about 2.5 pounds per cubic foot to 3 pounds per cubic foot.

Three pound density foam has a compressive strength of about 50 psi and an R-value of 7.14 installed and 6.86 aged (these numbers may vary slightly depending on the foam manufacturer.

Here's an example of how well a good SPF roof insulates. A school district in southern Alaska had recently installed some new, one-room relocatable classroom buildings.

During the late spring and early fall, these classrooms were using their air conditioners an average of 50 minutes every hour. The school district installed foam roofs on some of these classrooms in order to see if it would provide an energy savings. The roofs consisted of three pound density foam, 1.5 inches thick with an acrylic coating system.

The air conditioner usage was cut down to fifteen minutes every hour. That's a fifty-eight percent savings on energy costs.

Here are some brief examples:

 

• Seamless: Polyurethane foam is applied as a liquid, creating a single monolithic membrane that covers the entire roof. There are no seams or joints, the source of the majority of leaks in traditional roofs.

• Flexible: The foam can be sprayed onto virtually any surface, irregularly shaped roofs and protrusions are readily taken care of.

• Lightweight: Foam roofing typically weighs around 50 lbs. per square, versus 800 lbs. for a built-up roof and 100 lbs. for ballasted single-ply roofs.

• Thermal Insulation: SPF has the best insulating properties available for commercial construction today.

• Sustainability: Foamed roofs require a minimum of upkeep, creating little waste and have an indefinite lifespan.
