Here's What To Do About Curling Roof Shingles

Your roof is your home's first line of defense. It's also one of the most expensive parts of the property. Therefore, you're bound to get worried when you spot any signs of damage up there.

Curling roof shingles is one problem that will surely cause you concern. It's always a sign that your roof needs urgent attention. What is the main cause of curling roof shingles? What can you do about the issue? Adams & Sons Roofing, the most reliable roof replacement company in Sugar Hill, GA, breaks down all you need to know in the post below.

The Causes of Curling Roof Shingles

If you spot any signs of curling on your asphalt shingle roofing, it's usually due to one of the following causes.

Poor Ventilation in the Attic

If you have a poorly ventilated attic, most of the moisture in the rising air will get trapped within your roof's decking. Over time, the water damage will start to cause a range of issues, including mold growth, shingle curling, and more.

A well-ventilated attic can help prevent this problem, as the excess moisture will leave your home.

Poor Multi-Layering Work

Many homeowners choose to install a new roof over an old one to save on labor costs. However, it's rarely a good idea. There is a high risk of moisture trapping between the layers. Also, the new layer will be more susceptible to wind damage. Shingle curling will likely follow over time.

Poor Installation Work

Poor installation work is one of the leading causes of curling roof shingles. Asphalt shingles may look easy to install on the surface, but inexperienced installers can make mistakes during the process. Seemingly minor errors like using few nails or using undersized or oversized nails or failing to properly line up shingles to the tar line, can all lead to curling.

General Wear and Tear

Asphalt shingle roofs can last up to three decades with some maintenance. However, most standard options will start to show signs of old age around the 15-year mark. One of those signs might be curled shingles.

Low-Quality Materials

All asphalt shingles are not equal. Lower-quality options are more likely to curl at some point than higher-quality options. Therefore, it's always a good idea to only choose asphalt shingles from known manufacturers with a track record of excellence.

Extreme Weather

Extreme weather, such as unusual heat waves, can cause shingles to contract and curl. This is why experienced roofing contractors advise inspecting roofs after any major weather event.

What Can You Do About Curling Roof Shingles?

The approach you can take in dealing with your curling roof shingles depends on the severity and cause of the curling.

For Minor Curling

If you notice a few curled shingles after a storm, you can get them straight and flat again using roof cement. This can be a minor DIY job if you're in the right physical shape for it, though roofing work can be taxing on your lower limb muscles.

However, you can't go the DIY route if the curling is moderate or extensive or if it's due to a severe structural issue.

For Moderate Curling

If you notice curling shingles across 15%-30% of your roof's surface, it's time to call a professional roof repair crew. An experienced roof technician will first carefully evaluate the roof for underlying issues. If the roof is structurally sound, they will discuss repairing affected sections with you.

Fixing moderate curling often involves replacing the affected shingles. During the process, the repair team will:

  • Remove the nails still holding the shingles
  • Lay down a new shingle
  • Apply roof sealant
  • Nail down the new shingles with nails of the appropriate length

For Extensive Curling

If more than 30% of your roof's surface has curled shingles, the only thing you can do is to order a roof replacement. Repairs are no longer cost-effective at this point.

Your roofing technician will provide some professional guidance on whether you're due for roof replacement or not. But the best ones will always recommend a replacement if there's far too much curling.

What Happens When You Ignore Curling Roof Shingles?

It's not a good idea to ignore any type of roof problems, but most certainly not curling roof shingles. It's not a cosmetic issue. Ignoring it means exposing your home to the following issues.

Water Damage

You always expect a roof leak with missing shingles, right? The situation is the same with curled shingles.

The gaps created by the curled shingles are ways for water to enter into the roof structure and ultimately end up inside your home. This can lead to significant property damage, especially for people with finished or stocked attic spaces.

Loss of Energy Efficiency

Curled shingles cause a gap in your home's insulation. Your heating and cooling systems will work harder to reach your set temperatures as the heat (or draft) from the roof will counter their efforts. The result is an increase in your energy bills and more frequent HVAC breakdowns.

Structural Damage

If the water leaks due to the curling roof shingles continue long enough, the wooden components of your roof will start to deteriorate. Wooden components around your property may also be affected. Over time, you may have to replace the entire roof and also fix structural issues around your property.

Mold and Mildew Growth

Mold and mildew thrive in warm, damp environments. Unfortunately, they spread quickly. Ignore curled roofing shingles may leave you in need of comprehensive mold remediation services within a few weeks.

Decreased Curb Appeal

The curled shingles will make your property look older than it is. If you intend to put the property on the market any time soon, you have to fix the curling roof shingles or risk having evaluators shave off a few percentage points off your property's value.
