Roof granules are small, colored stones embedded in asphalt shingles and other roof coverings. Made from natural materials such as granite, quartz, or slate, these granules serve multiple purposes. They not only enhance the aesthetic appeal of the roof but also provide essential protection from UV rays, heat, and physical wear. The granules create a barrier that helps to prevent the roof's underlying materials from degrading due to sun exposure, moisture infiltration, and temperature fluctuations.
