Any roof can become a “cool” roof by applying a reflective roof coating. It can be done at any time while the roof has some useful life remaining.
A reflective roof coating reflects solar energy back into space instead of being absorbed by the roof surface. A “black” roof becomes incredibly hot in the heat of summer with temperatures exceeding 180F in some cases. The additional heat load on the roof makes your airconditioners work harder.
Per ENERGY STAR, they are roof coatings with properties of at least 65% reflectivity and 50% emissivity after 3-year aging.
A reflective roof coating is an excellent investment. The long-term benefits can help offset installation costs by providing:
