Foam Roofs


Spray Polyurethane Foam (SPF) roofing systems are popular for residential low sloped roofs in the desert southwest and are constructed by mixing and spraying a two component liquid that forms the base of an adhered roofing system. Foam roofing has distinct advantages over traditional roofing methods:

  • Seamless: Polyurethane foam is applied as a liquid, creating a single monolithic membrane that covers the entire roof. There are no seams or joints which are the source of the majority of leaks in traditional roofs.
  • Flexible: Foam can be sprayed onto virtually any surface. Irregularly shaped roofs and protrusions are readily taken care of.
  • Durable: Foam roofing is incredibly durable and highly resistant to extreme temperatures and storms.
  • Lightweight: Foam roofing is typically one-eighth the weight of traditional roofing materials, or around 33 lbs. per 100 square feet.
  • Thermal Insulated: SPF has the best insulating properties available for construction today.
  • Waterproof: Sprayed polyurethane foam is perfect for many different waterproofing applications. Because it is a closed cell system, the foam acts as an air barrier, while also preventing moisture infiltration into the home.
  • Sustainable: Foam roofs require a minimum of upkeep, creating little waste and have a lifespan of 35-50 years if maintained properly.

Protective Surfacings: Foam roofs have to be protected from exposure to the sun's ultra-violet radiation and moisture. The sun, wind, and rain will break down a calculable amount of surfacing compound each year and literally wash it and/or blow it away. Quality top coating helps to protect and seal the foam from any damage. The serviceable life of a well applied SPF roofing system is largely dependent on the quality of the protective surfacing applied and the degree to which that surfacing is maintained over time. Typically, recoating is recommended for 5 and 10 year intervals. These needs would be based on previous application rates and exposure.
