Asphalt shingles are widely popular in Mississippi, thanks to their affordable prices and classic aesthetic appeal. But with several positives come certain issues too, one of which we will cover today.
Due to several reasons, the edge of the shingles can curl, and this problem is common with the line of shingles that are placed just above the gutters.
If you’ve noticed your shingles are curling up right where they meet the gutter, you’re not alone. Understanding why it happens can save you a lot of hassle—and potentially a lot of money down the road. So, let’s break it down together.
Curling Shingles at the Gutter: What’s Going On?
While shingles are supposed to lie flat and create a protective barrier, curling shingles at the gutter area can be a sign that something is going wrong. When shingles curl at the gutter, it’s usually because of one of the following reasons.
The area near the gutters is a unique section of your roof because it’s where water tends to collect and run off. When your gutters are not doing their job properly—whether they’re clogged, too narrow, or not pitched correctly—water doesn’t drain away as efficiently as it should. Instead, it may pool or overflow in areas where it shouldn’t, leading to moisture getting trapped under the edges of your shingles. Over time, this trapped moisture causes the shingles to swell and distort, which leads to curling at the edges.
When water continually pools near the gutter edge and doesn’t drain away correctly, the shingles are continuously exposed to a damp environment. Over time, even if you have high-quality shingles, they aren’t going to hold up to that kind of constant wear and tear without showing some signs of distress, like curling.
Another factor contributing to this curling at the gutter is temperature variation. The edge of the roof, being more exposed, can undergo more drastic temperature swings than the rest. This repeated expansion and contraction due to temperature changes, combined with possible moisture buildup, weakens the shingles, making them more likely to warp.
Other Reasons For Curling Shingles
Your shingles are somewhat more vulnerable just above the gutters. But know that asphalt shingles can curl for a variety of reasons, not just near the gutter. Curling shingles, wherever they appear on your roof, can be caused by a combination of factors. Here are some of them:
Age Of The Shingles:
One of the most common reasons shingles curl is simply that they’re getting old. As shingles age, they lose their flexibility and start to become brittle. Over time, weather exposure—sun, rain, wind—takes its toll, and the shingles may start to break down. This wear and tear eventually causes the edges to lift or curl. Most shingles have a lifespan of about 20-30 years, so if your roof is nearing the end of that range, age might be the primary reason behind the curling.
Poor Ventilation in the Attic:
Your attic plays a bigger role in roof health than many people realize. Proper ventilation is essential because it helps regulate temperature and moisture levels. If your attic isn’t ventilated correctly, heat can build up underneath your roof. This excessive heat can cause shingles to dry out and become more prone to curling. Additionally, moisture that gets trapped in the attic can also lead to shingle deformation as the underside of the roof accumulates dampness.
Water Damage and Roof Leaks:
Wherever water is involved, there’s a good chance that curling shingles could follow. If water is allowed to seep under your shingles—whether due to leaks, poor flashing, or other damage—it can cause the shingles to warp and curl. Water damage often occurs when small leaks go unnoticed for long periods, allowing moisture to build up and weaken the shingle material. Even a tiny gap in your roofing system can let in enough moisture to start causing problems over time.
Manufacturer Defects:
While rare, some asphalt shingles may curl because they were defective from the start. Even when you hire a professional contractor and the whole process is done correctly, manufacturing defects can still cause the shingles to fail. Most shingle manufacturers such as GAF, Atlas, or Owens Corning offer manufacturer warranties, so if you suspect your curling shingles are due to a defect, it’s worth checking to see if they’re still under warranty. The company will replace these shingles for you.
Roof Pitch Issues:
The pitch, or slope, of your roof plays an important role in how water drains off of it. If the pitch is too shallow or not properly designed, water might not drain away efficiently, leading to pooling or poor water flow. In turn, this can lead to shingles absorbing more water than they should, especially during heavy rains, causing them to curl over time.
What To Do When You Spot Curling Roof Shingles?
If you notice that your roof has curled shingles, it is better to address them as soon as possible as the bad weather in Wisconsin will only increase the problem.
You will have two options in this case:
- Roof repair
- Roof replacement
If only one or two shingles are damaged, repairs are usually enough. This involves lifting up the curled shingle and applying a layer of roof sealant. You can try to do this yourself, but removing the shingles is not an easy job and we recommend a professional.
If the shingles have significant damage, it is time to replace them. Ensure you hire a roofer for this job.
How To Prevent Your Shingles From Curling Or Buckling?
Once you repair or replace the shingles, it is now time to be proactive. Here are some steps you can take to prevent your roof shingles from curling in the future:
Inspect Regularly:
Regular inspections can help catch issues early. Check your roof and gutters periodically to ensure everything is in good shape. If you notice any curling or other damage, address it sooner rather than later.
Clean Your Gutters:
Regular gutter maintenance can prevent water from overflowing and getting under the shingles. Keeping your gutters clean and in good repair can help extend the life of your roof.
Ensure Proper Installation:
If you replace your roof or install a new one in the future, ensure you always hire a professional roofing contractor in Wisconsin. A contractor will ensure that your shingles are nailed properly and are perfectly aligned. Also, check that the shingles come from a reputed manufacturer.
