Spray foam roofs are installed quicker than other roofing systems, due to:
- Most SPF roofing projects involve little to no tear off
- Spray foam roofs are spray-applied, meaning they can go around penetrations with ease
- Spray foam roofs require less material and equipment than traditional roofing systems
Because spray foam is quickly installed, business interruption and labor costs are minimized
Spray polyurethane foam is proven to be beneficial
Since the early 1960s, spray polyurethane foam roofs have been installed and recoated, strengthening the popular phrase “A spray foam roof is the last roof you’ll ever have to install”.
In recent years, spray polyurethane foam (SPF) insulation has seen significant growth in both general interest and acceptance as a high-performance solution to seal and insulate the entire building envelope. SPF insulation is energy efficient, durable, and helps create a comfortable building environment by helping keep homes warm in the winter and cool in the summer.
Because it is sprayed directly into the gaps, cracks, and other surfaces that contribute to heat loss, SPF both insulates and air seals, offering an easy and effective way of weatherizing existing buildings and new construction.
Spray foam roofs have a high R-value
Spray polyurethane foam has the highest R-value of any commonly used roof insulation. Here are the average R-values for some common roof materials
- Spray Polyurethane Foam: 6.6 per inch
- Metal: 0.00 per inch
- BUR Gravel: 0.34 per inch
- BUR Smooth: 0.24 per inch
- XPS Insulation: 5.0 per inch
- EPS Insulation: 3.85 per inch
- Polyiso: 5.5 per inch
R value is the capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power.
The higher the R value, the less heat or cool air that will pass through. Higher R value = less HVAC use = lower energy costs
Total payback of your new roof usually occurs in less than ten years through savings in heating and cooling costs.
Spray foam roofs are renewable
One of the benefits of a polyurethane roof is its ability to be re-coated.
A properly installed and maintained spray polyurethane foam roof should not require re-coating for 10 to 20 years. The best way to determine when a spray foam roof needs to be re-coated is to measure the remaining coating thickness on the roof and recoat before the coating is too thin to provide U.V. protection.
