Asphalt shingles are coated with protective granules. If you notice that your shingles are losing their granules, don’t be alarmed. This blog will tell you all about shingle granule loss.

Why Shingles Have Granules

Asphalt shingles are covered with granules that reflect the sun’s UV rays. That protects the shingles from damage and helps keep the interior of the house from getting too hot. Granules also make the roof more fire resistant.

Granules are applied for aesthetic reasons, as well. The granules are made with crushed stones and minerals and may have multiple colors to provide visual interest.

Why Shingles Lose Granules

Some granules are embedded in shingles and meant to provide long-term protection, while other granules are not embedded and are there to help protect the shingles during the installation process. Non-embedded granules fall off shortly after a new roof is installed. You’ll probably see them on the ground or in your gutters after a rainstorm.

Over time, temperature fluctuations, rain, hail, and wind can take a toll on asphalt shingles. Trees that scrape against the roof can also cause shingles to lose embedded granules.

When an asphalt roof loses its embedded granules, the shingles become more susceptible to damage. The loss of embedded granules can also affect the shingles’ appearance. 

What to Do About Shingle Granule Loss

If you recently had a new roof installed, you don’t have to do anything. It’s normal for a roof to lose granules shortly after installation. You might continue to see granules on the ground and in the gutters for a short period of time.

With an older roof, the loss of granules may or may not be a problem. It depends on how old your roof is, the extent of the granule loss, and the current condition of the shingles.

If you’re concerned about your roof, the best solution is to have an experienced local contractor conduct an inspection. A professional will be able to climb up on the roof, assess its condition, and tell you if the roof needs to be repaired or replaced.
