Abstract
An infrared-reflective material is applied directly to the bituminous surface of a roofing product to increase the solar heat reflectance of the product, even when deep-tone roofing granules are used to color the product. The infrared-reflective material can be applied as a powder or in a carrier fluid or film, and can be applied along with infrared-reflective roofing granules.
