If your house has an old shingled roof, you may start to worry that they are starting to wear down, increasing the likelihood of leaking. If so, look for the following signs that your old roof's shingles are starting to deteriorate.
Granules in Your Gutters
When your shingles are in good condition, they feel rough because of the tiny granules embedded in their surfaces. These granules help keep water from settling on the shingles so it flows down and off of your roof.
However, years of rain, wind and intense heat loosen these granules, making them fall off. As your shingles start to lose these granules, water is more likely to remain and eventually penetrate through the surface layers.
To see whether your shingles are losing their granules, look inside your gutters. As the water flows to your gutters, it will carry the granules with them. If you see a large number of granules in your gutters. there is a good chance that more than just a few of your shingles are deteriorating.
Pieces of Shingle on the Ground
Along with lost granules, another sign your shingles are wearing down is the presence of broken pieces on the ground around your house. As your shingles age and are constantly exposed to sunlight, they become brittle and prone to breakage during strong winds or from the impact of branches falling on the roof.
If you do find several pieces of broken shingle, you can check the condition of your other shingles by testing their ability to bend. While standing on a ladder at the edge of your roof, gently pull up the corners of several shingles, being careful not to break them. If they feel dry and start to crack, they have become brittle and may be prone to future breakage.
However, the broken pieces of shingles you find may not necessarily a sign of deterioration. They could also be a sign that a section of your roof was damaged during a storm. Have a professional check out your roof to discover the cause, especially if you find multiple pieces of broken shingles in your yard.
If you notice any of the above signs, some or all of your shingles may be deteriorating or broken. Contact a roofing contractor to have them come out and inspect your roof to determine the extent of the damage and determine whether your roof can be repaired or should be at least partially replaced.
