Shingles may be a popular choice when it comes to roofing materials, but that doesn’t mean they don’t have their problems. For example, they are notorious for cupping and curling. This is easily one of the most common problems with this type of roofing, and it can be very frustrating for homeowners who don’t understand why it’s happening. Are they doing something wrong? Is there a way to prevent this from being an issue? In this blog post, we will discuss the reasons why shingles cup and curl and what you can do to prevent it.
Why Do Shingles Cup and Curl?
To understand why, we first need to learn a little more about how manufacturers make them. Shingles use a variety of materials, including asphalt, fibreglass, and organic matting. Manufacturers combine these materials with other ingredients to create the finished product. The fibreglass reinforcement helps to add strength and durability to the shingle, while the asphalt acts as a waterproofing agent. The organic matting helps to give the shingle its shape and texture.
So, why do shingles cup and curl? There are a few reasons, but the most common is due to the asphalt. Asphalt is a petroleum-based product, and it can be prone to shrinking and hardening in certain conditions. When this happens, it puts stress on the fibreglass reinforcement, which can cause the shingle to cup and curl. This is more likely to happen in hot and sunny conditions, as the heat causes the asphalt to expand and contract.
There are a few other reasons why shingles cup and curl, but they are less common. For example, if your roof does not have proper ventilation, trapped heat and moisture can cause shingles to cup and curl. Improper installation can also contribute to this issue, as contractors who install shingles incorrectly can increase the risk of cupping and curling.
What Can You Do to Prevent Shingles from Cupping and Curling?
There are a few things you can do to prevent your shingles from cupping and curling. First, make sure your roof has proper ventilation. This helps prevent heat and moisture from becoming trapped beneath the shingles. Second, ensure a qualified roofing contractor installs the shingles correctly. This means following the manufacturer’s instructions and using the proper tools and techniques. Finally, if you live in an area with hot and sunny weather, try to keep your shingles out of direct sunlight. This will help to prevent the asphalt from expanding and contracting.
The Bottom Line
Shingles cup and curl for a variety of reasons, but the most common is due to the asphalt. If you want to prevent this from happening, make sure your shingles are properly ventilated and installed. You should also try to keep them out of direct sunlight if you live in an area with hot and sunny weather.
If your shingles are already cupping and curling everywhere, then the best thing you can do is replace them. This can be a big job, so you may want to hire a professional roofer to do it for you. That way, you can be sure it’s done correctly and your new shingles will last for many years to come. Thanks for reading!
