Why Do Asphalt Shingles Curl?

Have you ever looked around and taken in the scenic beauty of homes in your neighborhood? If you happen to glance at an asphalt shingle roof and notice crooked surfaces, take it as a case of curled shingles—a clear sign of maintenance neglect or quite simply a result of wear and tear.



Considering the roof is the main defense of your home against weather elements like rainfall and high winds, having curled shingles is alarming. Any damage to the shingles can allow water to leak into the property and cause further damages to insulation and belongings. Local roofing company Ken Morton & Sons LLC details the possible reasons why your asphalt shingles curl so you can detect them early on and avoid costly repairs to your home.

Poor Installation Practice

High-grade materials can only get you so far. Without the guarantee of expert installation, the asphalt shingles on your roof might not even reach the end of their service life. There are several instances that tell you you’re dealing with an amateur roofer, and this greatly involves the improper lining up of sealing strips that hold down shingle tabs. If the tabs are not placed securely, harsh winds can cause the shingles to move and eventually curl.

Reroofing Over Old Shingles

Reroofing over old shingles costs less and is quicker to finish than a total tear-off job. However, the layering of shingles ultimately comes with potential risks like premature shingle curling since it won’t be as secure. Another thing to take into account is the extra weight, considering that a single asphalt shingle is already thick and dense. If the old frames of your roof fail to support this newly introduced weight, then your roof may possibly collapse. Don’t wait for this to happen before you ask help from local roofers.

Insufficient Attic Ventilation

If your attic doesn’t receive proper ventilation, it can lead to moisture buildup and cause water vapor to condense in the roof sheathing. When this occurs, it’s only a matter of time until the high temperature loosens the sealing strip and initiates the curling of shingles.

You have to be thorough when it comes to inspecting the status of your roof. The smartest decision you can make is to call for the expertise of roofing professionals.
