What Does it Mean to Have Curling Shingles?

A roof with curled shingles is a common issue in Syracuse, NY. Curling shingles occur when the edges start to fold upwards and look like a cup (cupping). The process begins slowly, and the shingle will have a hollow or concave-like shape over time.

Not only are curling shingles negatively affecting the look of your roof, but they can also cause quite a bit of damage if left alone.

Once the process of curling shingles begins, it can't be undone or fixed, unfortunately. As the shingles curl, the roof underneath becomes exposed, which could potentially cause a lot of damage to the roof.

Depending on the severity of the curling shingles and how many have been affected, there may be an urgent need for roof repair. Keep reading for common causes of curling shingles on your roof.

Common Causes of Curling Shingles

Believe it or not, your home breathes. That’s right, it breathes. Homes will expand and contract with the temperature changes. Shingles are meant to withstand this very normal process, but as they age, the shingles will begin to loosen, curl, or deteriorate. If you find this is happening with a newer home or a newer roof, it can often be a sign of underlying roof problems. 

Regardless of the age of your home/roof, and even if you don't have water leaks, curling shingles are still a problem that must be addressed. Read on to learn about the common causes of curling shingles.

Moisture & poor ventilation

Hot air rises to the attic in your home. If the attic is poorly ventilated, the moisture from the air gets trapped in the decking, causing mold to form and shingles to curl. 

With moisture buildup caused by poor attic ventilation, moist air will get trapped between the materials that insulate your roof and attic. The excess moisture will cause damage not only to the decking but also to the shingles, likely making them curl. 

In the hot summer months, your poorly ventilated attic makes your air conditioner work harder, causing it to wear out more quickly and increasing your utility bill.

Multiple roofing layers

Often, it makes sense to add an additional layer of shingles to an existing roof. This is a cost-effective way to re-roof your home. However, the new roof shingles could be covering up an existing problem you may not be aware of.

Without a proper inspection, the original roof may have many damaged shingles or water damage. In this case, the new shingles may not be as secure, allowing them to be blown away in heavy winds. You can be rest assured with Melo Roofing’s inspections and roof repair process.

old age / normal wear & tear

If your asphalt roof is more than 12-15 years old and the shingles are curling, you may need to replace the curled shingles or get it re-roofed. Doing so can help you avoid more extensive damage and repairs in the future.

poor installation

Sadly, not all roof replacements are completed correctly. If the wrong nails are used, or used in the wrong spot, your shingles could curl up. Additionally, an adhesive strip is often used to help line up the shingles.

If that isn’t applied right, the shingles could deteriorate and even fly off with a strong gust of wind. If you feel that you had an improper installation, call Melo Roofing to resolve the problem quickly before more damage occurs.

If your roof's asphalt shingles have started to curl, it's probably a good idea to have them repaired. Curling and missing shingles can lead to leaks in your roof, leading to water damage. 

If you notice particles in your gutter or around your house, this may be a sign that your roof is deteriorating. In Syracuse, NY, where we have harsh winters, roofs must be able to withstand temperature changes and winter weather strong winds, snow, and ice.

Can You Fix Curling Shingles?

Well, the short answer is no. Once shingles have curled, they are damaged and need to be replaced. There are a variety of instances where shingles need to be replaced. Curling, blistering, and missing shingles are all common reasons for replacement. While shingles replacement can be done DIY style, it is safer and better to have a professional complete the task. 

Your roofing contractor will inspect your roof and determine the severity of the curling shingle problem. Based on their evaluation, they will determine the best way to remedy the problem. The contractor will also look for additional damage to the roof, including missing shingles and water damage.

The damaged shingles will then be removed and replaced with matching new shingles. Once complete, you’ll want to maintain the roof with regular inspections.
