Roof Coating

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. It adds an additional layer of protection placed on a finished roof.

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. Most roof coating products have the ability to expand and retract along with roof materials as weather conditions change. This allows the material to stay adhered to the roof surface and to protect it from ruptures.

Typical roof coating dry film thickness vary from paint film (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.

Applied reflective roof coatings can extend the useful life of nearly every roof substrate by keeping the surface cool and providing a level of protection from the sun and weather. Field studies have shown that cool roof coatings can lower rooftop temperatures and reduce air conditioning bills. Another benefit from using the roof coating is it can sometimes as much as double the life of the roof.

Applying the roof coating can involve several different methods. It can be applied with the paintbrush, roller or spray gun. Most manufactures recommend using a spray gun to apply the coating to give a more even layer of product. Different roofs require additional layers or coats and the weather conditions in the area.
