Roof Shingle Granule Loss

However not all granule loss is a concern.

Roof shingle granule loss.

The first thing is to increase the roof pitch. 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. You may find evidence of this in your gutters or sometimes in your yard. Over the years granules begin to erode and fall off.
