Should You Worry Over Asphalt Shingle Granule Loss?

Asphalt is the most popular roofing material in the country thanks to its durability, weather resistance and value for money. It’s remarkable for its ability to shed water, giving any roof it’s installed on excellent waterproofing.

Should You Worry Over Asphalt Shingle Granule Loss

Asphalt granules comprise the outermost surface of a typical shingle and while long-lived, are not permanent. Spring Valley Roofing, your local roofing contractor, shares a few things about granule loss.

Don’t Worry If…

An asphalt shingle roof naturally sheds granules as it ages, which end up in the gutters or on the ground beneath the eaves. This deterioration of the roofing material is the result of constant exposure to the elements.

The negative effects of granule loss aren’t always visible until the roof gets sufficiently old, which shouldn’t be an issue as you’ll likely be replacing the roof. Avoid performing roof repair on a roof that’s noticeably bald already, as you’d simply spend money that would have otherwise been better spent on a newer, better roof.

Start to Worry If…

Granule loss also occurs due to roof blistering. These small protrusions, while often just manufacturing defects, happens when moisture builds up underneath the topmost layers of the roof. Such blisters are the first signs of wear on the shingles, leading to an abnormal shedding of granules.

While blister-related granule loss is alarming, it’s not too late. Preventive roof repair usually addresses these issues by keeping the blistering from getting worse.

Do Worry If…

Wind damage is one of the biggest culprits of premature and extensive granule loss. Tree limbs and branches can scratch and tear at the surface of the roof, displacing the granules and puncturing the surface. Address wind-related granule loss as soon as possible because it makes the entire roof susceptible to leaks.
