Are Your Asphalt Shingles Buckling? Take A Look At Common Causes

About Me
Keeping Your Roof In Decent Shape

After listening to a few friends of mine complain about the cost of replacing their roof, I realized that I should make sure that my own roof was in decent shape. I climbed up on a ladder to see if I could see the shingles, and things weren't looking very pretty. Some patches of shingles were missing entirely, while others looked badly damaged. Fortunately, I caught the damage early enough that experts could patch up the issues. However, since roofing damage isn't always obvious, I decided to put up this website so that others can spot trouble of their own.

Are Your Asphalt Shingles Buckling? Take A Look At Common Causes

Your asphalt shingle roof should have a pretty good lifespan of at least 20 years or more, according to U.S. News. Obviously, asphalt shingle roofs are not going to last forever; therefore, they will have some problems, and buckling is probably one of the most common homeowner complaints. The only thing is, buckling sometimes happens right after installation and this can cause some major concerns. Buckling is a term that is used to refer to what happens to shingles when they turn up or shift into an awkward position. Take a look at some of the common causes of shingle buckling right after an asphalt shingle installation. 

The roof sheathing was not acclimated before installation. 

The sheathing, sometimes called the underlayment, is a thin wooden material that goes in place under the felt paper and under the shingles. If the sheathing is brought in from a different place and is not properly acclimated, it can cause the sheathing to change shape after it is in place. The best roofing contractors know that the wooden sheathing should come from a local source or from a place where it has been allowed to naturally adjust to the climate before installation. Bowing can occur if acclimation is not allowed, and this will cause the shingles to buckle. 

The felt paper was saturated with water when it was installed. 

Felt paper should be kept completely dry before it is installed onto the roof. Some inexperienced DIY roofers assume that if the felt paper is a little damp, it will not cause all that many problems. However, the damp felt paper will change shape as it retains moisture and then dries. The problem with this is, the felt paper goes down directly underneath the shingles. Therefore, if the felt paper shifts after it goes into place, it can cause the shingles to buckle as well. 

The asphalt shingles themselves are absorbing and holding water. 

This is a common problem with older shingles because of the tendency for the protective tar to wear away with age, which causes water absorption problems. However, newer shingles that are made in a poor quality way may also take in water and hold it, which can cause buckling as well. If you have a newly installed roof and the shingles are buckling, take a good look at the shingles to see if they appear to be porous or holding water.
