Here’s Why Your Asphalt Roof Is Losing Granules

Asphalt shingles continue to be one of the more popular roofing materials in America. Aside from its attractiveness and relatively low cost, asphalt shingles are durable roofing materials, thanks to the granules embedded on their surfaces.

These granules give asphalt shingles the ability to withstand ultraviolet (UV) rays and also give them added fire resistance. Over time, however, these granules are loosened, get carried into the gutters and washed away when it rains.

Why is your asphalt roof losing these granules, you might ask? There are a variety of reasons:

Your Roof Is New and Has Excess Granules

One reason could be related to manufacturing. New asphalt shingles might have poorly embedded granules. These will get loosened and will be washed away when it rains.

Your Roof Is Old

Old asphalt shingle roofs are more likely to shed off granules than new roofs. This is because the bond between the granules and the shingles are loosened, allowing granules to fall away.

Your Shingles Are Blistering

Your asphalt roof can lose granules when it has blisters. Moisture, which can come from storms, can cause blisters on your shingle roofing. Once your roof begins to have blisters, more granules will fall off. Time to call the best roof repair contractor in the area!

Physical impact

Your shingles will also shed granules when they are hit by something hard. As such, foot traffic, falling tree branches, hail and other things can cause granules to become loosened and fall away from your shingles.
