New Roof Shingles Buckling

You also may have curling shingles where the center of the shingle looks concave and the edges turn up.

New roof shingles buckling.

Asphalt shingles sometimes buckle slightly and in an irregular pattern due to moisture in a the materials of a new roofing system. If the felt paper is rained on it s best to let it dry out before installing shingles. This sheathing is generally made from plywood or a similar material. This is what we call buckling.

Roofs buckle because either the roofing underlayment has wrinkled or the wood deck itself has shifted for some reason. The wetness gets absorbed by the felt underlayment causing the felt to wrinkle. 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. But the moisture evaporates as the materials reach equilibrium with the the surrounding air and the shingles settle back down flat.

It is caused as a result of the movement of the wood roofing deck or wrinkling of the underlayment. And this is a serious problem because if minor buckling is not addressed it could require a full roof replacement. Shingle buckling is one of those awful things that can happen to a roof through no fault of anyone. Buckling shingles are a sign of a major problem with your roof.

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. It doesn t matter how old or new your roof is buckling shingles indicate it needs a professional inspection right away. Occasionally the buckling is caused by poor workmanship wrong materials or possibly by a problem with the structure itself. This then telegraphs to the shingles above.

Another cause of buckling can be wetting of the felt paper which will expand if it gets wet. In new construction it is best to let the roof sheathing acclimate to local conditions before installing the roofing although this is not always practical.
