Granule loss happens when the protective mineral granules on asphalt shingles wear away or become displaced. Those granules help protect shingles from sunlight and weather.
Why It Matters
As shingles lose granules, the asphalt layer below has less protection. That can speed up aging and make the roof more vulnerable to wear.
Common Problems
Homeowners may see granules in gutters or downspouts, dark worn patches on shingles, or shingles that look thin, shiny, or uneven after storms.
Exterior Echelon Notes
Exterior Echelon checks granule loss along with shingle age, ventilation, storm exposure, and other signs of roof condition.
