What Causes Curled Shingles

No homeowner wants to look at the exterior of his or her home and see roof damage. Such damage may lead homeowners to think they need a new roof, a potentially costly expense that can quickly throw household budgets into a state of disarray.
According to the HomeAdvisor, the average homeowner spends a little more than $7,600 installing a new roof. Various factors, including the size of a home and the type of roof homeowners prefer, will affect the cost of a roof replacement. In addition, homeowners who see roof damage can rest assured that not all roof problems will necessarily require a replacement roof to be installed.
Curled shingles are a problem many homeowners have encountered. This particular problem is not always indicative that a roof is on its way out. In fact, the home improvement resource This Old House notes that, as asphalt shingles age, their corners often begin to curl downward or upward. Homeowners who notice this early enough can glue down the curled section of each shingle that’s beginning to curl.
Some shingles may be curling because they’re defective. Fortified Roofing, a New Jersey-based roofing company that specializes in the repairing and replacing of various roofing configurations, advises homeowners to contact a local roofing professional to diagnose the cause of the curling. Doing so quickly can prevent curled shingles from contributing to more widespread damage.
Moisture and poor ventilation may be contributing to curled shingles as well. Homeowners with attics in their home may see curled shingles on their roofs because moisture is building up in their poorly ventilated attics. In addition to causing damage such as curled shingles, a poorly ventilated attic allows moisture to build up, potentially contributing to mold growth. Mold presents a host of additional problems, including some that can adversely affect the health of a home’s inhabitants.
Improper roof installation also may be the culprit behind curled shingles. When a roof is not installed correctly, shingles may not be aligned or nailed down in the right way. This might be what’s causing shingles to curl on recently installed roofs.
Curled shingles are unsightly and can pose a significant threat to a home if not addressed promptly. Homeowners can protect themselves and their roofs by working with skilled roofing professionals, who can diagnose issues like curled shingles and offer the right solutions.
