A roof coating is a monolithic, fully adhered, fluid applied roofing membrane. It has elastic properties that allows it to stretch and return to their original shape without damage.
Typical roof coating dry film thickness vary from paint film thickness (plus or minus 3 dry mils) to more than 40 dry mils. This means a roof coating actually becomes the top layer of a composite roof membrane and underlying system. As such, the roof coating is the topmost layer of protection for the membrane, receiving the impact of sunlight (both infrared and ultraviolet (UV), rain, hail and physical damage.

Roof coatings are seamless and when installed correctly, can solve roof leaks on almost any type of roof substrate. Field-applied reflective roof coatings can extend the useful life of nearly every roof substrate keeping a roof surface cool and providing a level of protection from the sun and weather. Roof coatings can add 25 years[1] to the service life of a roof and reduce the amount of discarded roofing materials that end up in landfills. The infrared image on the right shows "175°F" on the uncoated (black) section of the modified bitumen roof. The coated (white) section is "79°F". Field studies have shown that cool roof coatings can lower rooftop temperatures and reduce air conditioning bills.[2]
Roof coatings are easy to install[3]. Smaller roofs in good, serviceable condition can be a weekend DIY project. Larger roofs with leaks and ponding water issues should be restored by a qualified professional.
