Asphalt shingles should not curl on your roof; but when they do, you should be concerned. Curling is a symptom of a bigger problem that needs inspection and fixing.
Credentialed residential and commercial roofing contractors like Mobley Brothers Roofing and Renovation would agree that the most logical explanations for shingle curling are below.
The Asphalt Shingles Are Old
Aging roofing shingles absorb moisture unevenly. Thanks to volatiles, asphalt shingles are waterproof and flexible. However, these chemicals dissipate over time. Shingles become more absorbent as they lose more volatiles.
Experienced residential and commercial roofing contractors would attest that volatile dissipation does not progress at a similar rate. Generally, the edges of shingles become deprived of these chemicals faster than the rest. As a result, they are the first ones to deform.
The Attic Is Too Hot
Shingle curling could also be the result of extreme heat originating from the attic because of poor ventilation. When the bottom side of shingles is exposed to high temperatures regularly, they wear out faster.
The Installer Disobeyed the Manufacturer
Shingles should be installed according to manufacturer instructions. One mistake could lead to shingle curling, so it is imperative that you hire a crew with proven expertise in the asphalt-shingle product you want to buy. For instance, you should use the residential and commercial roofing services of a GAF Master Elite® contractor if you want Lifetime Shingles.
The Problem Products Are Defective
If you have a relatively new roof with an adequately ventilated attic installed by a qualified crew, a case of shingle curling may point to a product defect.
Your warranty protection should be able to cover it. so file a claim to receive a reimbursement for the replacement materials and the cost of labor necessary to install the new components.
