Should I Replace My Roof When I Notice Granule Loss?

It’s already known that granule loss is a roofing issue that must be addressed immediately. Similar to any dilemmas, when this is neglected, it may lead to more complicated concerns. But when do we really have to get our roofs replaced when this appears?

Shingle Granule Loss

This 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 roof.

Remember that your system will be exposed to different weather conditions, temperatures and elements. Should bald spots begin to appear, the affected areas will show the black shingle substrate. Hence, roofing repairs are inevitable.

Other Common Causes of Granule Loss

1. 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.
2. 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.
3. Foot traffic: When you get a new roof, some granules may become detached from the shingles if someone walks on them. Bald spots on your roof are effects of excessive foot traffic. 
4. Aging: Out of all causes, this can never be avoided. It is certain that roofs are expected to deteriorate over time due to various reasons.
