Why Do Shingles Cup and Curl

When it comes to roofing, Collingwood is often a place where weather plays a huge part in the health and longevity of your home. Cupping and curling of the shingles occurs due to the natural expansion and contraction of asphalt shingles caused by temperature changes. Asphalt shingles are made up of a mat and a top layer of asphalt which expand in hot temperatures and contract when the temperatures drop. This causes the edges of the shingle to curl up or “cup”, creating an uneven surface that can eventually lead to missing shingles, water damage, and more. But why does it happen, and what do you do when it does? 

What Causes it?

Shingles cup and curl due to changes in the weather. When temperatures drop, the shingles become brittle and can crack or break. When the temperature rises, they can become soft and curl up at the edges. This is a common problem that most homeowners face when it comes to roof maintenance. To prevent this from happening, it is important to be aware of how changing weather conditions can affect your shingles and take appropriate steps to protect them.

How to Prevent it

The first step to preventing cupping and curling is to make sure you have the right shingles to suit your home and climate. Secondly, you should always have a yearly inspection of your roof by a professional roofing company, to make sure your shingles are still in good condition. Finally, you may need to apply a new coat of sealant to protect your shingles from further weather-related damage. Taking these steps can help ensure that your roof remains in good condition and continues to protect your home from the elements.

What to do When it Happens

If cupping or curling does happen, it’s important to take action as soon as possible to prevent further damage to your roof and home. Fortunately, there are a few steps you can take to repair cupped and curled shingles and restore the integrity of your roof. This includes inspecting the shingles for signs of damage, removing any loose or damaged shingles, replacing them with new ones if necessary, and applying sealant to help protect them from future weather exposure. You should also check for any signs of water damage, such as moss or algae growth, and remove it if found. With these steps in place, you can keep your roof in top condition and avoid costly repairs down the line.
