Under normal circumstances, asphalt shingles are designed to lay flat and create a smooth, secure surface that protects the interior of your home. However, if you look up and begin to notice that they are curling upward, there is a cause for concern. There are several reasons why this might happen, many of which require a professional contractor to investigate your roof installation. Here’s what you should know before you schedule that initial appointment.

Why Are Your Roof Shingles Curling?

1. Multiple Layers

Sometimes homeowners choose to apply a new roof installation over an older, existing one. However, this isn’t usually a good idea, especially if the original roof was in poor condition. The issue is that the shingles on the new system aren’t as secure as they would be on fresh underlayment, which renders them more vulnerable to loosening when exposed to wind or other weather conditions.

2. Poor Installation

During the roof installation, contractors secure each shingle with nails. If those shingles eventually curl, it could be because there weren’t enough nails holding it down, or the nails were positioned in the wrong areas.

3. Poor Ventilation

A lack of ventilation inside your attic can wreak havoc with the roofing system. When the space is adequately ventilated, heat and humidity circulate through the area and can escape. If this doesn’t occur, the air just below the roof remains stagnant. If the moist air comes into contact with the roof’s underlayment, it can cause mold to develop, which can force the shingles to curl upward.

4. Natural Aging

The age of the roof is often an indicator that structural issues may begin to occur. The anticipated life expectancy of an average asphalt roof installation is approximately 25 to 30 years, assuming regular maintenance. Once it reaches that stage, its integrity has likely weakened dramatically. As a result, it’s more vulnerable to issues like wind and rain, which can cause shingles to loosen up and curl.
