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. You also may have curling shingles where the center of the shingle looks concave and the edges turn up. 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. Buckling shingles look like something is underneath the shingles pushing them upward.

But the moisture evaporates as the materials reach equilibrium with the the surrounding air and the shingles settle back down flat. The wetness gets absorbed by the felt underlayment causing the felt to wrinkle. 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.

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. Buckling shingles are a sign of a major problem with your roof.
