Benefits of spray foam roofing!

Benefit number 2 it is lightweight

Polyurethane spray foam roofs are typically a lot lighter than other roof systems greatly reducing the roof load we see compounded in winter by lots of snow living in the upper Midwest States of Illinois, Indiana, Iowa, Michigan, Minnesota, Wisconsin and others. One inch of spray foam insulation plus 30 mils of an elastomeric coating weight approximately 65 pounds per 100 square feet, as compared to approximately 600 pounds per 100 square feet for a typical conventional four-ply built-up roofing system.

What are the benefits of spray foam roofing?

Benefit #1Energy  Efficient = Energy Savings

Rising energy prices have prompted a new wave of interest in energy efficiency in the United States. Spray foam roofing provides superior insulation compared to traditional roofing systems and with the Upper Midwest’s harsh weather, spray foam is a must have. The seamless layer of polyurethane foam has zero fasteners, seams and keeps energy locked in. Studies have shown that through gaps and metal fasteners, as much as 38% of the insulating value can be compromised. Benefits include:
Eliminate Thermal Drift
Reduce HVAC cost
Zero Seams
Eliminate Condensation
Reduce/Eliminate Ice-Dams
The application of spray foam (SPF) will provide better climate control within a building envelope. Better climate control reduces the consumption of fossil fuels, thereby reducing greenhouse gases released into the air.

Generally, SPF shows little sign of deterioration or change in physical properties even after 40 years when properly installed. Studies show SPF roof systems can pay for themselves in about 4 1/2 years through energy savings. Any roof is the primary surface of thermal absorption from the sun and consequently, the roof is the surface responsible for the majority of energy loss of a building.
Since a spray foam roof has the highest R-Value rating of any commercially available insulation on the market, it wasn’t a surprise when a study conducted by Texas A&M University and Ford Motor Company (each has millions of square feet of SPF roof systems) documented that the spray foam roof system actually paid for itself in 4 1/2 years through energy savings. Each 1” of Sprayed Polyurethane Foam provides an R-Value =7. Typically, on most roof applications, a 2” average SPF thickness is achieved providing an R-Value =14 contrasted against a traditional modified or built-up roof system which delivers a much lower R-Value.
