What Causes Asphalt Shingles to Curl?
Curling shingles is a common problem with asphalt roofing. It can indicate that your roof is not in good shape and needs repair. You should never ignore this problem if you want to delay the need for a roof replacement.
Read on to find out what causes asphalt shingles to curl.
Multiple Layers of Roofs
When getting a new roof, you can either go for a complete tear-off or an overlay. In a tear-off, the old roofing material is removed before installing the new one. Meanwhile, in an overlay, the new shingles are installed over the old material. Having multiple layers of roofs can result in premature shingle curling. The new shingles won’t be as secure, meaning they are more likely to get blown off by strong winds.
Insufficient Attic Ventilation
If your attic is poorly ventilated, warm, moist air can buildup in the area and get trapped in the decking. This can result in mold formation and shingle curling. To ensure your attic is properly ventilated, get regular inspections from experienced roofing contractors.
Poor Roof Installation
Even if you invested in quality roofing materials, your roof may still experience early deterioration due to poor installation. Curling can occur if your roofer did not use enough nails to attach the shingles or improperly placed the nails. Insufficient nails will eventually cause the shingles to loosen and fall.
Roof Is Reaching the End of Its Life
Aging is the most common cause of shingle curling. If your roof is at least 15 years old and is experiencing this problem, it’s likely nearing the end of its life. It would be better to replace your roof now before it starts to leak, which can cause issues to different parts of your home.
