Urbana Roofers: Article About Curling Shingles
In order to protect the roof, asphalt shingles need to lie flat against the roof. Over time, it's common for the shingles to start to curl up at the edges. Unfortunately, this leaves parts of the roof exposed to the elements, and it's a sign that it's time to have some Urbana roofers come fix the problem. Depending on the age of the roof, it may be necessary to completely replace the roof. In younger roofs, curling is a sign or product failure or improper installation.
One of the primary reasons that shingles curl is from experiencing temperature fluctuations between hot and cold. Though the shingles are generally designed to withstand this for 20 years or more, over time, the expanding and contracting can mean that the materials start to break down. Since the edges are not nailed down, they curl up.
If there is improper ventilation in the attic, the curling may be more likely to happen. An overly warm attic transfers that heat to the shingles through the roof. The heat can cause this warping.

While it's normal for shingles to curl as they age, if shingles that are only a few years old are starting to curl, the homeowner should call the company who did the installation. Curling shingles can occur when the shingles were not nailed down properly during the installation. They can also occur when the weather conditions during the installation were not ideal. Another scenario is if the roof does not get hot enough for the shingles to seal. For this to happen, the roof needs to reach a temperature of around 70 degrees Fahrenheit, or the contractor needs to take additional steps to make it happen.
When it seems that the problem could be happening due to product failure or improper installation, the homeowner can usually rely on the warranty or roofing company's guarantee to cover the cost of the damages. When it's the result of normal aging, though, the homeowner will be responsible for the full cost of repairs or replacement. The more curling that's visible, the higher the chances for damage to the roof. Any homeowner that's noticing the shingles starting to curl needs to think about replacing the entire roof or the damaged shingles as soon as possible.
Despite the pressing need to get the shingles fixed, it's still important to carefully choose the roofing contractor. Ask for written estimates and referrals and make a decision only after comparing a few companies.
