Shingle Granule Loss: Should It Worry You?

Asphalt is the most popular roofing material in America due to its durability, natural weather resistance and value. It also has water-shedding capabilities, allowing it to serve as an excellent waterproofing layer for shingles.

Shingle Granule Loss: Should It Worry You?

The granules on asphalt shingles, however, are not permanent and the roof will eventually lose them. Read on as Barnhouse Exteriors, LLC, one of the top roofing companies in Minneapolis, shares a few notes about granule loss.

When Granule Loss Is Normal

An asphalt roof naturally sheds its granules as it ages. They usually end up in the gutters or on the ground beneath the eaves. This slow degradation of the roofing material is the result of constant exposure to rain and sun.

The negative effects of granule loss aren’t noticeable until late in the roof’s life span. This is not that worrisome as at that point, you’ll be replacing the roof anyway. As one of the top full-service roofing companies in Minneapolis, Barnhouse Exteriors, LLC is always ready to assist homeowners with their roof replacement needs.

Shingle Blistering

Granule loss also occurs due to roof blistering. These small protrusions, while often considered a manufacturing defect, also results from built-up moisture damage on the roof. They are far from just cosmetic defects, however, as they are actually the first wear points on the shingles, causing them to shed a large number of granules.

While blister-related granule loss is alarming, you can do something about it. By performing preventive roof repair on the shingles, you can stop the blistering from getting worse and prevent further loss of granules.

Wind Damage

The roof can also lose its granules due to wind damage. Tree limbs can scratch and tear at the surface of the roof, displacing the granules and causing puncture damage. Wind-related granule loss needs to be addressed as soon as possible as it makes the entire structure susceptible to leaks.
