An asphalt shingle consists of a mat core that is coated with many layers of asphalt. The top layer of the shingle is coated with pulverized minerals, which become embedded in its surface. This, in turn, provides the shingle with a protective top layer that functions to not only physically protect the inner layers and core of the shingle, but also to protect against the sun’s ultraviolet rays.
Why Do Roof Shingles Have Granules?
Mineral granules were added to the design of shingles because they help protect your roof from excessive sun exposure, which can eventually lead to damage and hasten the need for a roof replacement. Granules also add increased fire resistance to your roof, offering another layer of protection to your home.
Why Are the Granules Coming Off?
Asphalt shingles have pulverized minerals embedded on their surface. In fact, they are so covered with minerals, some excess material is bound to fall off. Since each shingle has so many, you usually don’t have to be concerned about finding granules in your gutters, especially if your roof is relatively new.
If you are noticing granules in your gutter system or downspouts – or if you simply notice that the tiles are “balding”, this means that your roof materials are eroding, and do require some attention from roof repair experts.
Do I Need to Replace My Roof?
Granules help keep your roof weatherproofed, so without them, it’s easier for the sun and water to cause roof leaks and deterioration. However, shingle granule loss does not always mean you need a full roof replacement.
If you are seeing a large number of granules on a regular basis, and you start to notice that your shingles look spotty or bare in areas, you should call a roofing professional to take a look before you have a leak.
