Granule Loss: Should I Replace My Roof?

There could be many factors to consider before getting a roof replacement. But when does granule loss become a sign of this? TJ Exteriors Inc. will share more information about this common dilemma that most homeowners should be aware of.

Shingle Granule Loss

This problem occurs on organic-mat or fiberglass-mat asphalt roof shingles. Depending on the cause and extent of mineral granule loss, the loosening of this protective coating can spell the end of life of an asphalt shingle roof or the demise of a mineral-granule-coated roll roofing roof.

As most roofing contractors would note, this is inevitable because your roofing system gets exposed to different weather conditions, temperatures, and elements. Should the bald spots begin to appear, the affected areas will show the black shingle substrate. Remember that shingles that experienced granule loss have more porosity. This means there may be already leaking even if water damage is not yet obvious inside your home.

Other Common Causes of Granule Loss

1. Foot Traffic. Whenever someone walks on your roof, some of the granules may become detached from the shingles. Bald spots on your roof are effects of excessive foot traffic.

2. Hail Damage. As mentioned, it is highly likely that severe weather, such as hailstorms, may damage shingles producing pitting and granule loss. Depending on the severity of the conditions, it will create significant damage to your roof.

3. Blisters. These can occur due to manufacturing defects or poor attic ventilation. When someone walks on these blisters, it can leave visible defects like granule loss.
