Spray polyurethane foam roofing may have been around for over 40 years, but it’s not as mainstream as other roofing structures. Learn what makes SPF different from the rest.
Flat roof sprayed polyurethane foam, also known as SPF, is liquid-sprayed material that’s been around since the 1940s. SPF is constructed by mixing and spraying a two-chemical solution consisting of isocyanate and polyol. Roofing professionals use transfer pumps that heat and apply material. As it’s sprayed, it expands to many times its original volume in a matter of seconds.
While it expands, it forms a rigid foam plastic that chemically bonds to the surface. Then, spray polyurethane foam roofing contractors apply an elastomeric coating (typically acrylic, silicone, or polyurethane) or an aggregate covering, which provides waterproofing and UV protection.
Although spray polyurethane foam roofing is mainly for industrial or commercial buildings, it’s also suitable for residential properties. This eco-friendly roofing system has many benefits, including:
SPF provides thermal, air, and moisture protection since the liquid fills any openings that could become problematic. In addition, polyurethane keeps heat out in the summer, which lowers energy costs for facility owners. Because the roof’s surface reflects UV rays instead of absorbing them, the building stays cooler naturally. This means your thermostat will be stabilized throughout the hotter months and indoor temperatures will stay cooler and more comfortable.
Seams and penetration points cause leaks in other roofing systems. Luckily, with SPF, this vulnerability is eliminated. Since SPF is liquid-sprayed, it fills gaps and cracks in the roof’s deck. Contractors also level the roof’s surface during application to reduce the chances of pooling water.
SPF roofing is a sustainable option since it requires minimal stripping of the original roof. Often, it eliminates expensive roof tear-offs and waste and SPF is installed on top of the existing structure. SPF roofing has many other environmentally friendly benefits, including:
If the SPF is applied correctly the first time, it lasts with semi-annual inspections. These routine checkups help catch red flags early on so they can be addressed sooner than later and the roof maintains its integrity. Although SPF materials are lightweight, they’re durable and long lasting. It may also sustain damage from hailstorms and other inclement weather, but it’s easily repairable without compromising its lifespan. Also, if recoating is needed, the new coat is applied directly to the original system.
Hire roofing contractors with a proven track record of excellence.
The cost of the average SPF roofing installation ranges anywhere from $6,000 to $7,200. Costs depend on the slope, pitch, and condition of your current structure. Expect to pay $2.50 to $3 per square foot on a standard sized or single-story building. It offers a worthy return on investment as well, since it lasts 20 to 30 years with proper installation. That’s why it’s crucial to hire professional roofing contractors to complete the project to save yourself time and money on repairs later down the road.
