Asphalt shingle roofs are by far the most popular roofing material in use in the United States today and for good reason. They are a favorite among roof repair companies and homeowners alike because they are relatively inexpensive, widely available and very easy to install. In fact, according to a recent study, approximately 75% of American homes are protected by an asphalt shingle roof.
Another key to asphalt shingle roofing’s popularity is the tiny granules that cover its outer surface. But what are they, and what purpose does it serve?
Asphalt Roofing Granules
Asphalt shingles are made by soaking a mat in asphalt and covering it with a mixture of granules composed of slate, schist, vitrified brick, quartz, stone or ceramic. This mixture of granules does an excellent job of blocking ultraviolet (UV) light from the sun and provides protection to the shingle’s asphalt core resulting in a more durable and weather-resistant roof that will last many years before a roof replacement becomes necessary.
Is It Normal for Your Shingles to Lose These Granules?
As the old saying goes, nothing lasts forever, and the constant exposure to the elements will slowly erode this protective coating on your shingles. Flying debris, rainstorms and strong winds all contribute to granular loss and are a normal sign of an aging roof. If you notice that your shingles are becoming “bald” or that there is an unusual amount of granules in your gutters, this means that it is nearing the end of its service life and will probably need to be replaced soon.
