Common Reasons Why Asphalt Shingles Curl

The roofing system is one of your home’s main lines of defense against the elements. Without it, your home is left vulnerable to moisture infiltration and the subsequent damage it can cause. Unfortunately, since it’s exposed to the elements 24/7, 365 days of the year, you can expect your asphalt roof to show some signs of wear and tear eventually. One of these signs is curling. But how exactly does shingle curling occur?

In this article, The Great American Roofing Company, the roofing pros who offer a reasonable roof replacement cost, reveals the common reasons why asphalt shingles curl.

Improper Installation

Improper installation of the shingles are one of the main reasons why your asphalt shingles curl. It’s possible that during the installation, your roofer didn’t use enough nails per shingle or they didn’t place it properly. Once this happens, the insufficient amount of nails holding the shingle down or the poor placement can cause the shingles to eventually work itself out and leave it loose, allowing curling to occur.

Age

Alternatively, if your roof is more than two decades old, it’s likely that your roof is approaching the end of its lifespan and must be replaced soon. By doing so, you’ll save yourself a significant amount of time and money in the long run. For assistance in replacing your old roof, don’t hesitate to enlist the services of an expert roofing company to get the job done.

Poor Attic Ventilation

Hot, moisture-filled air can rise to your attic and if your attic’s ventilation system is inadequate, it can cause wood rot on your roof deck and bake your shingles from the inside, which in turn results in the curling of your shingles and reduction of your roof’s expected lifespan. With that in mind, make sure to have a professional inspect your home’s attic ventilation and have it upgraded if needed.

Improperly Lined Shingles

Each shingle comes with an adhesive strip known as the tar line and if this tar line wasn’t properly lined up by your professional, it won’t adhere properly. This means that your shingle will be left vulnerable to eventual curling and could be potentially blown off by strong winds.
