Spray foam (or Spray Polyurethan Foam - SPF) is an ideal roofing material for flat roofs, which are so common in the America Southwest, thanks in large part to the influence of the Spanish Colonial architectural style. Foam is a combination of two chemicals that is heated and fed through a spray gun. When applied, the mixture expands and tiny air bubbles are trapped within the foam, making it particularly effective at insulating the roof, both from heat and cold. Those air bubbles make SPF extremely energy efficient — studies have shown that foam roofing frequently produces energy savings of 30% or greater when compared to other roofing systems.
Residential foam roofing advantages:
Foam roofing is highly energy efficient:
Foam roofing offers amazing energy efficiency. One study at Texas A&M University looked at 27 buildings and found that the savings in energy costs over 4.5 years would pay for the cost of the roof installation. Another study by the Oakridge National Laboratories documented cooling and heating energy costs that were reduced by 50%.
Minimal maintenance required:
Foam roofing requires infrequent maintenance checks and generally very little repair is needed. An inspection every five years or so should be satisfactory unless you suspect damage from hail or impact debris. If a foam roof is damaged, it should be repaired immediately by professional foam roofers to prevent leaks or other problems.
