4 Reasons Your Shingles Are Curling & What You Can Do About It

If the shingles on your roof are curling, you should know this particular problem isn’t merely a minor aesthetic annoyance. Rather, curling shingles are often the result of more serious roofing issues that, with time and lack of attention, will only grow worse. What might be causing your roof’s shingles to curl? Our roof repair team at Eastern Roofing & Siding explains the four most common culprits below.

Improper Installation

When you had your roof built, did you opt for budget roofing materials and a low-priced roofing contractor in an effort to keep your roof installation costs as low as possible? If so, subpar installation may be the culprit behind your curling shingles.

When a roofing contractor uses too few nails — or nails that are too short — to secure the shingles to the roof deck, the edges of each shingle are free to move and bend. Shingles that aren’t properly lined up with the adhesive tar line on the underlayment can also experience the same problem.

What’s the fix? Contact a roof repair specialist to get a comprehensive inspection. If there are only a few curling shingles, roof repairs can probably fix the issue. On the other hand, if the problem is widespread, it may be time to start thinking about getting a total roof replacement.

Poor Product Manufacturing

Despite quality control measures and other roofing industry safeguards, it’s possible for defective materials to end up in the hands of roofing suppliers. Those materials are then distributed to roofing contractors, and ultimately, they end up getting installed on homeowners’ roofs.

Unfortunately, defective shingles can begin curling just days after installation, so if you just had a new roof installed and the shingles look horrendous, subpar material quality may be the issue. If your roof came with a workmanship warranty, it should cover any necessary repairs or replacements. Contact the roofing contractor ASAP to discuss the problem and your roof repair options. 

Inadequate Attic Ventilation

If your attic doesn’t have enough venting, it can get remarkably hot in there. Unfortunately, excessive heat can do considerable damage to the underside of shingles since that side doesn’t feature the same protective granules that the outer surface has. Over time, the heat essentially melts the base layer of the shingle, causing it to warp, and eventually, that warpage prompts the edges of the shingle to curl.

What’s the fix? If poor ventilation is causing your shingles to curl, you’ll need to handle the heat issue in your attic first. A roofing contractor can install additional vents to increase airflow or unblock existing vents that may be clogged. Once you have the ventilation issue under control, you’ll need to have the damaged shingles replaced.

Moisture Intrusion

If any amount of moisture seeps beneath the edges of your shingles, it can cause them to warp and curl. Worse, that moisture can damage the underlayment and the roof decking, ultimately leading to mold proliferation, rot development, and eventually, structural deterioration. 

If you believe moisture may be the culprit behind your curling shingles, prompt attention is critical. Check your attic for signs of water, mold, or mildew, and call a roofing contractor immediately to schedule an inspection.
