Why Are Your Shingles Buckling And What Should You Do About It?

by Vanessa Lord

If you look up on your roof and see that some of your shingles have begun to buckle, you should be concerned. Buckling shingles can quickly lead to leaks. They also expose the underlying wooden portions of your roof to moisture, which can lead to rotting and deterioration. Here's a closer look at why your shingles may be buckling and how to address this issue.

What causes shingles to buckle?

Buckling shingles can sometimes be traced back to mistakes made during roof installation even though the buckling may not show up for a year or two after you get a new roof. Under your shingles, there is a layer called the roof sheathing. This sheathing is generally made from plywood or a similar material. The pieces of sheathing are supposed to be spaced about 1/8-inch apart so that they have room to expand and contract as the temperature changes. If your roofer does not leave enough space between the pieces of sheathing, when the boards expand, one board might rise up over the other. This can push the shingles out of place, causing them to buckle.

There are a number of other issues that can contribute to buckling shingles on a smaller scale. A lack of ventilation may expose the sheathing to excess moisture, causing it to expand more than normal and subsequently leading to shingle buckling. Sometimes a leak that is left unaddressed may also expose the sheathing to moisture and have similar consequences.

How can buckling shingles be fixed?

Unfortunately, fixing buckling shingles can be a pretty involved project. Since the problem usually originates not with the shingles, but with the sheathing, the affected area of the roof usually has to be stripped of shingles so that the sheathing can be replaced. Any other issues, such as leaks or a lack of ventilation, will also have to be addressed, otherwise the roof will just buckle again.

If the buckling is determined to be caused by a lack of space between sheathing pieces, you will probably need to have the whole roof replaced. Any areas that are not yet buckling will eventually buckle if left long enough. If your roof was replaced recently, give the company that put the roof on a call. If a mistake was made when your roof was installed, they may be willing to cover part of all of the cost of repairs.
