Asphalt shingle roofing protects millions of homes from the elements. A common issue that occurs with this roofing material is curling. If you notice something is wrong with your roof, you need to schedule an inspection immediately. Also, it’s not a good idea to delay repairs, because the damage could spread to other areas of your house.
Continue reading to learn what causes asphalt shingles to curl.
Multiple layers of roofing. If you need a new roof, one option you have is to install new shingles over the old ones. Experts don’t usually recommend this route, but many people still do it because of the lower cost. While it might be cheaper upfront, there can be consequences later. For example, high winds can easily curl and tear off the second layer of shingles.
Insufficient attic ventilation. All roofs need proper ventilation in order to last a long time. A lack of airflow will cause attic temperatures to rise, speeding up the deterioration of roofing components, including shingles. Moisture can also accumulate in the space if there’s insufficient ventilation. As a result, mold growth will occur, and shingles will begin to curl.
Poor shingle installation. Incorrect nail placement and using an insufficient number of nails in the shingles are also common reasons curling occurs. The sides of the shingles can easily lift if there aren’t enough nails to secure them. The same goes if these nails are placed in the wrong positions. You can easily avoid these issues by working with a dependable roofing contractor for your project.
