Still shingle roofs do present a unique maintenance issue known as granular loss.

Roof shingle granule loss.

However other things can cause this too such as tremendous rains hail branches strong wind storms and exceptionally intense hot and sunny days. Walking on shingles causes some of the granules to fall off your roofing system. This thermal expansion and contraction can lead to granule loss and cracking over time. Once this erosion of the granule has taken place the life of the shingle is basically over.

With older roofs even marble size hail may loosen granules. Granule loss which is uniform across the roof is usually a result of normal weathering. Granule loss is common after severe weather like hailstorms. Some other aging clues are curling at shingle corners lack of tab adhesion and broken off pieces as the shingles get more brittle with age.

Roof shingle granule loss due to defective roofing product usually exposes the shingle substrate in premature bald patches and is identified by bald spots or exposed shingle substrate on roofs early in their chronological life often distributed uniformly over the roof or in areas of the roof where shingles from a particular pallet of roof shingles were installed. These bald areas could be an indication that someone has carelessly walked on your roof. Roof shingles are covered in tiny colored chips known as granules. Because granule loss is one of the signs that a roof is getting older it is used by inspectors as a gauge of roof condition and a way to estimate additional roof life.

These granules help to protect the asphalt from harsh environmental conditions such as uv light and heavy rains. If a contractor is working on your roof or chimney keep an eye out for bald spots that may start appearing. Depending on the level of granule loss and age of your roof you may be able to replace the damaged shingles without having to get a new roof. Prolonged exposure to hail can also loosen granules.

Over the years granules begin to erode and fall off. The first thing is to increase the roof pitch. Granule loss indicates aging of a roof. Granule loss occurs when the embedded granules begin to loosen and fall off the shingle.
