When it comes to identifying damage to your roof, it's easy to fall into the trap of thinking that if your shingles look fine, the roof's health is as it should be. While curled and missing shingles are certainly a sign that your roof needs to be repaired, there are a variety of other issues that you may overlook but that are just as important in alerting you that it's time to call a roofing professional. When you know what to look for, you stand a greater chance of being able to catch issues early on, which means that they'll be cheaper and easier for your contractor to fix. Here are some "other" types of damage that you may notice.
Issues With Roof Vents
When you're looking at your roof to check its shingles, make sure to also inspect the roof vents. They're integral for allowing the exchange of air between your attic and the exterior of your home, but they can face several issues. For example, if water gets under the flange at the base of a roof vent and the temperatures drop, the water will turn to ice and may lift the flange away from the roof. This could allow water to trickle into your attic. Additionally, twigs, feathers, and other material around the opening of a vent suggests that a bird has made a nest in the vent, which will block the flow of air.
Problems With Roof Flashing
The flashing on your roof describes the strips of weatherproof material that are found at roof joints. For example, if there's an elevation change in your roof, there will be a strip of flashing in this area. Over time, due to ice damage and other factors, this flashing can lift away from the roof. Fortunately, you'll often be able to see this issue from the ground. Look for the flashing to be smooth, flat, and snug to the roof — if it appears lifted, buckled, or split in any areas, it will need to be replaced.
Appearance Of Moss
If you can detect mossy patches on your roof, this is a concern to share with your roofing contractor. This issue is prevalent if part of the roof is in the shade for much of the day, which may occur if your yard is heavily treed. Moss favors damp areas, which means that these shingles are staying damp, and this could increase the risk of an attic leak.
