Granule Loss in Asphalt Shingles: Should You Be Concerned?

Have you noticed a scattering of tiny granules in your gutter or driveway? These could be coming from the asphalt shingles on your roof. Granules are a crucial component of these shingles but, over time, they may begin to shed. If you’re encountering granule loss in your roofing, you’re likely wondering just how serious this issue could be. Continue reading to learn more.

Causes of Granule Loss

Asphalt shingles, commonly used in many American homes, consist of a base mat, asphalt coating and mineral granules on top. These granules offer a protective layer against UV rays, enhance fire resistance, and provide the color and aesthetic appearance you see on your rooftop.

Granule loss could result from natural aging, harsh weather conditions or physical damage. Be it a branch hitting your roof during a storm or heavy wind blowing away the granules, your shingles may gradually start to lose their protective covering.

Impact of Granule Loss on Asphalt Shingles

Reduced Weather Protection: The granules on asphalt shingles act as a protective barrier against various weather elements, including UV rays, rain, snow and hail. When granules are lost, the underlying asphalt layer becomes exposed, which can lead to premature deterioration and water infiltration. This can result in leaks and costly water damage to your home’s interior.

Reduced UV Resistance: The sun’s ultraviolet (UV) rays can be extremely damaging to roofing materials. Granules help to shield the shingles from UV exposure, preventing them from drying out and becoming brittle. Granule loss can accelerate the aging of shingles, making them more prone to cracking and curling and becoming less effective in protecting your home.

Reduced Curb Appeal: Granule loss can also impact the appearance of your roof. As shingles lose their granules, they may develop discolored spots or appear uneven in color. This can diminish your home’s curb appeal and potentially affect its market value.

Reduced Longevity: Asphalt shingles are designed to last for several decades, but granule loss can significantly reduce their lifespan. Shingles that lose a large number of granules prematurely may require replacement much sooner than expected, leading to additional expenses.

When Is Granule Loss a Problem?

Seeing granules in your gutters or driveway doesn’t always indicate a problem. The volume lost over time determines whether the loss is normal or excessive. If you notice large patches of bare shingles or the roof deck exposed, it’s high time to call a roofer.
