As a general rule, asphalt shingles last for about 20 years assuming normal weather conditions and that they were properly installed. Let’s take a look at some clues that the shingles on your home need to be replaced in the near future.

You Notice That One or More Shingles Are Missing

If you notice that one or more shingles have blown off of your roof, it is important to have the structure inspected immediately. This is because exposed roof decking could provide water or pests with a prime entry point into your home. If water or pests get into your home, it could result in significant damage to the walls, floors or even the foundation.

Furthermore, you may reduce your home’s curb appeal by not repairing exposed or damaged portions of a roof. A contractor that has experience with asphalt roof shingles in Peachtree City, GA, may be able to diagnose the problem and help mitigate it.

Algae Is Growing on the Roof

While it isn’t uncommon for algae to grow on older asphalt shingles, it is a problem that needs to be addressed in a timely manner. Allowing it to remain on your roof could result in damage to shingles, decking and other components. A roofing contractor that repairs or installs asphalt roof shingles in Peachtree City, GA, may be able to provide insight into how to solve your algae problem. In some cases, it may be possible to extend the useful life of a shingle by cleaning it.
