New roof shingles buckling.

But the moisture evaporates as the materials reach equilibrium with the the surrounding air and the shingles settle back down flat. It doesn t matter how old or new your roof is buckling shingles indicate it needs a professional inspection right away. 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. This then telegraphs to the shingles above.

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. 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. 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.

The wetness gets absorbed by the felt underlayment causing the felt to wrinkle. If the felt paper is rained on it s best to let it dry out before installing shingles. Hard to tell from one photo but if the buckling followed the pattern of joints in the roof sheathing it can be caused by installing shingles over sheathing before it has had time to reach moisture equilibrium with the homesite environment. This sheathing is generally made from plywood or a similar material.

Under your shingles there is a layer called the roof sheathing. Buckling shingles look like something is underneath the shingles pushing them upward. Asphalt shingles sometimes buckle slightly and in an irregular pattern due to moisture in a the materials of a new roofing system.
