What are the Causes of Roof Shingle Curling?
Have you taken a look at your roof lately and noticed that the shingles are not as flat as they used to be? If you have noticed that your roof’s shingles are beginning to curl, you may wonder why this is happening and whether you need to take action. There are several reasons why your roof shingles could be curling, and you will need to call a professional to assess your roof and make repairs. Here are the four most common reasons why your roof shingles are curling.
Poor Ventilation in the Attic
Since heat rises, your attic is typically the warmest place in your home. If you have proper ventilation, then additional heat is not necessarily an issue; however, if you have moisture mixed with hot air and in a properly ventilated attic, you can begin to see problems such as curling shingles. The humidity is getting trapped in the attic, and mold is likely collecting under the roof, which causes the shingles to curl.
Shingles Were Improperly Installed
There is a tar line on the back of each shingle, which is used to line it up when installing it on your roof. If this is not lined up correctly, the timelines are not appropriately aligned, and the shingles will not adhere correctly. This will eventually lead to the curling of the shingles.
Additionally, suppose the original roof installer used the incorrect number of nails per shingle or failed to place nails and shingles properly. In that case, this will result in subpar work, leading to issues such as curling shingles. Always ensure that you hire a licensed professional to avoid having your roof installed incorrectly.
Age of the Roof
One of the most common causes of curling shingles is the age of your roof. If your asphalt roof is 12 to 15 years old and the shingles are beginning to curl, you should consider either a new roof or re-roofing. Waiting will only cause more problems with shingles and even water leakage.
Multiple Layers
If your roof already has two layers of shingles and you have curling shingles, then it’s time for a complete roof replacement. Many homeowners add a second layer of shingles as a cost-saving measure to the existing roof. Installing a second layer is very common; however, it is not as secure as the base layer of shingles and can be more susceptible to the elements. One of the most common issues with reroofing is curling shingles over time.
If you have noticed curling shingles on your roof, don’t wait another minute. Call a professional roofer to assess the condition of your roof before you end up with significant damage due to water leaks. Call the experts at GDC Contracting Inc. for all of your roofing needs.
