5 Causes of Granule Loss on Asphalt Shingles

Granule loss can either be caused by normal wear on shingles or a defective roofing product. The granules are bound to the shingles during manufacturing to protect them from ultraviolet rays and natural elements.

In this post, your leading residential roofing expert, Earl W. Johnston Roofing, LLC, discusses the potential causes of granule loss on asphalt roofs.

New Asphalt Roof

New roofs tend to shed some granules, so if your roof is relatively new and you’re noticing granules in the gutters or on the ground, this is not a cause for concern. It’s likely that the granules became loose as the installers walked on the roof surface.

Aging

Granule fallout is normal on aging roofs. Long-term exposure to harsh weather, the sun and changing temperatures can compromise the flexibility of the roof. An asphalt roof may have reached its end if the granule loss has left the surface with huge bald spots. Roofs like this need to be replaced. When you need a roof repair or replacement services, you can count on Earl W. Johnston Roofing, LLC.

Blistering

Blisters may just be a cosmetic manufacturing defect, but, in some roofs, they are warning signs of wear on a shingle’s upper surface. Severely blistered roofs can lead to visible damage, such as granule loss or pits.

Foot Traffic

Mineral granules embedded on the shingle surface can loosen when there’s too much foot traffic. You may notice bald areas on your shingles after a roofing job. Older roofs can suffer both granule loss and cracked shingles when they’re walked on.

Storms

Hailstorms and heavy rainfall can damage the shingles and result in granule loss. The lifespan of the roof may be affected depending on how bad the damage is.
