In North America, asphalt shingles are the most widely used roofing material on residential properties. These roofing shingles are coated with protective granules that serve numerous important functions. Keep on reading to learn more about asphalt shingle granules — an exterior remodeling contractor will guide you through.
An asphalt shingle is traditionally made of a base mat from either an organic or inorganic material. This mat is saturated with asphalt and then topped with mineral granules, which are often made of a mixture of slate, ceramic, stone, quartz, schist, or vitrified brick.
The surface granules on asphalt shingles provide a certain level of protection to the asphalt core and are instrumental in blocking out ultraviolet light from the sun. They also give the shingle its ability to effectively shed water and resist fires. Light-colored asphalt shingle granules are known to be better at reflecting sunlight and keeping the home cooler year-round than dark-colored ones.
Since the mineral granules are responsible for absorbing the brunt of sunshine, they can deteriorate due to the wild, persistent heat. According to a residential roofing service provider, severe rainstorms during the spring and summer seasons can also cause the protective coating to erode. Other factors that contribute to granular loss include windswept debris, overhanging tree limbs, and algae and moss buildup.
If you see an excessive amount of granules in your gutters or downspouts, this means that your roofing material is eroding and in need of professional attention. Once a shingle is eroding, you run the risk of water-related damage such as leaks, mold, and rot. What you need to do is bring in a qualified roofer to perform needed repairs or, if the damage is extensive, a full-on replacement.
