Foam roofing is a modern option for flat roofs, providing a good ratio money-quality. Like any other roofing option, it comes with pros and cons.
The material is Spray Polyurethane Foam (SPF), which is not so expensive and can be applied with ease, considering that it comes as a spraying liquid. The foam is distributed over the existing roof, regardless its shape and type, and makes any surface uniform, effacing irregularities. Spray Polyurethane Foam can be applied directly over metal, wood or asphalt, once the existing roofing materials have been cleaned.
Another significant advantage of SPF is that is provides energy efficiency, as well as moisture protection. Building owners will pay less for energy bills regardless the season, considering that the foam keeps heat out in the warm season and in during the cold season, while also being resistant to UV radiation, and can be installed quickly by an expert in Denver commercial roofing.
A roof covered with Spray Polyurethane Foam is not so vulnerable to water leaks, considering that the foam fills efficiently gaps and cracks. Using the foam, the roof can also be leveled to avoid ponding water.
A SPF roof requires only minimal maintenance and it will last up to 50 years. It must be inspected yearly and recoated with silicone if necessary, to prevent tear-off of the existing materials.
As for the cons, they are mainly related to the application of the PFA, which must be done with precision, by professional roofers, who understand the process and the chemicals they are using.
