Why Do Asphalt Shingles Curl?

Asphalt shingles are one of the most popular roofing materials in the United States, and for good reason. They are very affordable and protect your home against the elements while providing great curb appeal enhancement. However, just like every other roofing system, it has its fair share of drawbacks. Without proper maintenance and inspections, asphalt shingle performance will degrade over time. One of the unique cases of asphalt roofing damage are curled shingles. The damaged shingles can either be replaced or repaired, depending on the severity of the case. 

Why Do Asphalt Shingles Curl?

Curled shingles can often be found near or around the edges of your shingle tab. Oftentimes, the damage can be spotted at the first or at the lower edge, but it can also be found at two sides of the shingle tab. It’s common to encounter shingle curling issues, but their root cause can differ. Here are some of the top causes of asphalt shingle curling:

  • Moisture Accumulation
    Having too much moisture can be traced back to lack of ventilation or moisture absorption by your roof’s decking during the roof replacement process.

  • Roof Overlay
    Roofing experts like us highly discourage roof overlays as it won’t last as long as a full-blown roof replacement project. Granted, it can save you money in the short run, but if you leave your home’s old roof on, the new layer of shingles won’t be fully secured unless the old roof is removed. In turn, this makes your asphalt shingles susceptible to curling.

How to Treat Asphalt Shingle Curling

Depending on the scale and the cause of the damage, repairing curled shingles can only be considered as a temporary solution. Repairing curled asphalt shingles won’t fully bring back your roof to its original condition, even if a professional roofer has accomplished the job. It’s also dangerous to walk on curled shingles since they are brittle and can easily break off. As such, you can do temporary repairs depending on the material, but you’re better off getting a new roofing system for your safety and long-term savings. Granted, it costs more upfront, but the long-term savings are unparalleled.
