The outer layer of asphalt shingles has mineral granules to bolster your roof’s weather resistance. Over time, you may find a considerable amount of them collecting inside your gutter system and on your landscaping. So, what does this mean about the condition of your roof? Continue reading as trusted roofing contractor M&A Exterior Home Improvement explains this matter further.
A Normal Part of Roof Aging
Granule loss in asphalt shingles isn’t necessarily an indication that a roof replacement is due. In fact, the shedding of grit occurs right after installation. Excess granules may fall off the asphalt shingles’ outer layer as the installers walk on your roof. Granule loss happens gradually as your roof is exposed to wind, rain and hail for many years. It is not something to worry about since it is a normal part of your system’s aging process.
A Sign of Impending Roof Replacement
While you can always chalk up roof aging as the reason behind granule loss, there will come a time when you’ll have to get in touch with your local residential roofing company. This is especially true if you started noticing the following:
- Blisters. Moisture can find its way underneath your asphalt shingles, causing them to expand whenever they’re exposed to the sun’s heat. A quick inspection may reveal small, pimple-like bumps on the surface of the shingles. These are blisters, which dislodges the outer layer of mineral granules and exposes the shingle matting.
- Hail Damage. Dense hailstones hitting your shingles can leave cracks and dents upon impact. As this happens, some of the mineral granules on the shingle surface get knocked off, leaving your roof exposed to further moisture damage.
If you see granule loss to the point where your asphalt shingles have bald spots on a significant area of your roof, it’s time to consider having the entire roof covering replaced. One way to know for sure is to have it inspected first by a reliable roofer like M&A Exterior Home Improvement.
