Granules are an important part of asphalt and composite shingles. Without granules, your shingles will quickly fail. If you're a homeowner, you should be able to tell when your shingles are shedding granules at a quick pace; you should also know what to do about this problem.
Why Do Roof Shingles Lose Granules?
Roof shingles lose granules steadily throughout their service life. In the years before your roof shingles start to deteriorate, your shingles will still shed a few granules here and there. When granules start to shed faster, this is usually a sign of age. Shingles that are past their prime will shed granules very quickly, and will soon become bald.
Sometimes shingles will lose granules because of hail damage. Large pieces of hail that fall on a roof may create pock marks and, ultimately, bald spots. This is not generally a common problem as it takes fairly large pieces of hail to create this problem.
If your relatively new shingles are balding and your home has not been through a recent hail storm, your shingles may be defective. Talk to you roofer to alert them to the problem.
How Can You Tell When Your Shingles Are Balding?
When your shingles start to go bald, one of the first indications of a problem will be the appearance of granules in your gutters and in the outlet where your downspouts are located. You should not be able to scoop granules out of your gutters by the shovelful. If you can, this is likely a sign that your shingles are failing.
After the problem becomes very advanced, you'll also be able to see the bald spots on your shingles. Balding shingles may appear to be discolored, because the granules and the paper beneath are usually two different colors.
What Problems Do Balding Shingles Experience?
The granules contribute to the water resistance of your home's asphalt shingles. As the shingles start to lose granules, they become more likely to leak. Granules also shade your shingles from harmful UV rays, so a loss of granules can speed up the deterioration of your roof.
If Your Shingles Are Balding, What Can You Do?
If your shingles are losing granules, the best thing you can do is talk to your roofing contractor. Hail damage can often be fixed by replacing individual shingles, as long as the damage is not too wide spread. If the shingles are getting old, your contractor will likely recommend that you replace your roof.
New shingles that are losing granules may be covered under a warranty. Your roofing contractor can talk to you about next steps to fix this problem.
What Are the Other Signs That Your Roof Is Aging?
If your roof is aging and needs to be replaced, here's what you'll likely see:
- Shingles curling around the edges
- Missing shingles or shingles appearing in the yard after storms.
- Leaks after rain storms
- Stains on the ceiling
- Mold in the house
- High humidity in the house
- Sagging or warping in the roof
If you notice any of these signs of a problem, talk to your roofing contractor. Your roofing contractor can assess the condition of your home's roof and recommend repairs as needed. If your home needs a new roof altogether, the contractor will be able to give you a quote for a roof replacement. Get several quotes from different contractors before hiring someone to do the job.
