Curling shingles are a common roof problem. Most homeowners notice the issue when the edges of their shingles begin to curl upward. Typically, this is the first indicator that something is wrong with the roof and needs to be repaired or replaced. 

Curling shingles are caused by several factors, and they can have an array of additional impacts on your home. To find out the exact reasons your shingles are curling, you’ll need a roofing company to perform a thorough roof inspection as soon as possible. Don’t wait; when left untreated, curling shingles could cause additional damage. 

5 Reasons Your Shingles Are Curling

Curling shingles are never a good sign for your roof. If you’ve noticed some curling, acting quickly is essential. A residential roofing company can help you determine precisely what caused the problem, so you can take the necessary measures to extend the life of your roof. 

These are the most common reason your shingles are curling: 

1. Poor Ventilation

If your attic is poorly ventilated, all of the moisture from the rising air tends to get trapped in the decking, which will cause mold to form, and shingles to curl as a result. This occurs because hot, moisture-filled air rises. 

A well-ventilated attic can prevent this problem because it circulates excess moisture and pushes it out of the home. 

2. Multi-Layered Roofs

Installing a new roof over an old one usually leads to premature shingle curling. When a roof is installed using this method, the shingles on the second layer are less secure and easily blown and curled by strong winds. 

Although it is not often recommended, some homeowners layer their new roof over an older one to save money on the installation. Using this method can cost more money in the long run, and if it’s the cause of your curling shingles, you’ll need to replace the entire roof. 

3. Improper Installation

Missing or incorrectly placed nails are also possible reasons your shingles are curling. This typically occurs because too few nails are used, or they need to be placed in the correct spots, thus allowing the shingles on your roof to become loose over time. Depending on the amount of improperly installed shingles, you may be advised to repair or replace your home’s roof. 

4. Misalignment

When the adhesive strip on the back of each shingle fails or is placed incorrectly, the shingles on your roof will be misaligned. This will leave portions of your roof exposed to the elements and can result in curled shingles.

5. Wear & Tear

Unfortunately, nothing lasts forever – not even your roof. The normal wear and tear of your roof will cause it to deteriorate. Over time, the heat, rain, and snow will take their toll, leading to curled shingles. If it’s been more than a decade since your roofing was replaced, more than likely, it’s time for a new roof. 

What Are the Effects of Curling Shingles? 

When left unrepaired, curled shingles can cause devastating damage. Water is the biggest threat to a faulty roof, and curled shingles will let it seep into your home’s structure. 

The most common effects of curling shingles include the following: 

  • Leaks
  • Structural damage
  • Mold infestation
  • Decreased air quality
