Reasons Behind Granule Loss in Asphalt Shingle Roofs

June 4, 2021 by Heritage Roofing

If you see some black bits of material collecting inside your gutters or lying around in your yard, don’t disregard them. These are granules that protect the surface of your asphalt shingles roof. Granule loss can be a cause of concern because it means that the roofing material is either defective or showing signs of aging. Read on as we discuss the common reasons why asphalt shingle roofs tend to lose their protective granules.

Roof Installations

It is not uncommon for granules to come loose during an asphalt shingle roof installation project. Excess granules can be found on the packaging of the roofing product. Expect them to scatter and find their way inside gutters as the pros handle and nail the shingle pieces.

Shingle Blisters

Some asphalt shingle pieces may have pimple-like protrusions on the surfaces of asphalt shingles. While these are usually considered “cosmetic” manufacturing defects, they can become the first wear points on the shingle. Exposure to weather and foot traffic can lead to roof surfaces riddled with small round dots that are indicative of missing granules.

End of Service Life

Asphalt shingles display various signs of damage over time, especially when the residential roofing system reaches the later years of its lifespan. In addition to granule loss, the affected shingle pieces may have other problems like buckling and cupping. As your expert local roofing company, we recommend having your roof inspected to check whether it needs to be replaced as soon as possible.

Wrong Installation Methods

Inexperienced roofers commit even the smallest mistakes during installation, resulting in problems that include asphalt shingle granule loss. Take the “laddering” technique used in laying down shingles, for instance. Here, shingles aren’t installed side-by-side; rather, each shingle is installed without moving beyond the reach of both sides.
