Foam insulation is a great way to keep the heat out in the blistering, Arizona months, and retain heat when it cools down. However, foam alone and exposed will become dry and deteriorate under the relentless rays of the sun. It is the elastomeric coating that protects the foam and the light, white coloring that further deflects the rays of the sun.
Without proper maintenance of this coating, you risk extreme damage to the foam underneath the coating. With consistent maintenance, that foam can last 30 years on your home! Recoats should take place every five years to give your foam roof the best chance to protect your home!
