Why are granduals from my roof on the gr. This is due in part to the installation process where handling and walking on the shingles dislodges granules from the asphalt. These uv rays will rapidly disintegrate asphalt and the thin fiberglass mat. But usually it just knocks granules off the surface.

What causes granular loss. Ones that have lost their granules will be black and look more like a uniform surface compared to the lighter visibly granulated shingles around them. If you don t have gutters because you live in a place where it seldom rains you can climb up to your roof don t walk out on it and look at your shingles.

Granules also add increased fire resistance to your roof offering another layer of protection to your home. 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. Shingle granules shield the shingles from uv rays and increase their fire resistance.

One of the ways asphalt shingles have been perfected over the years is with granules. Granule loss on a new asphalt roof loose mineral granules wash down the roof and will appear in gutters and at the ends of downspouts. More granules fall off around the damaged spot and the bruise grows.
