Spray Polyurethane Foam, or SPF, is a roofing system that has been used commercially since the 1970s. It was first introduced as a product in the 1950s and was used mainly for refrigeration and industrial insulation until it was adapted into a roofing system. There have been a number of popular misconceptions about SPF’s durability, affordability, and installation over the years, and we want to clear some of those up.  


Many believe that foam roofs are less durable than roofs made of other materials. It may seem logical to assume that, but there is in fact no known lifespan for a properly installed and maintained spray foam roof. When SPF is installed, it should be coated with a rubberized material known as an elastomeric coating. This coating keeps the foam sealed, and roof maintenance is as easy as using acrylic caulking to reseal foam that has been exposed by the wearing down of the coating. Spray foam roofs are as strong as they are durable. Properly installed, a foam roof can hold forty pounds per one square inch, so feel free to walk on it.  


Misconceptions have lead many to believe that spray foam roofs are expensive, but the opposite is true. SPF is not only one of the most affordable commercial roofing systems available today but also one of the most reliable. As the prices of alternative roofing systems continue to rise, spray foam roofing prices have remained consistent and low. Don’t forget that spray foam is also used for insulation! An SPF roof serves as great insulation for your building and will make it more energy efficient.


The improper installation of spray foam roofing over the years has lead many to believe that the installation process is unreasonably difficult, which it is not. The key for SPF roofing systems is to find the right people to do the job! Use an A1 Roofing & Waterproofing, LLC roofing contractor in Miami for your commercial roofing needs!
