Why Are There Buckled Sections on My Shingled Roof, and Could Damaged Roof Decking Be the Cause?

Buckled sections on a shingled roof can be a sign that there is an issue underneath the shingles. In some cases, the board or plywood substrate may be damaged, deteriorated, or have movement at the seams, which can cause the shingles above to buckle or appear uneven. Moisture intrusion, aging materials, or movement in the roof deck can also contribute to this type of problem.

At Anchor Point Roofing, we thoroughly inspect buckled areas to determine what is causing the issue. As part of the roof repair, we will carefully remove the shingles and synthetic felt over the affected area so we can thoroughly assess the underlying substrate, whether it is board decking or plywood.

If we find damaged or deteriorated roof decking, we will replace the affected section with new decking as needed to provide a solid and stable surface for the roofing materials. We will then install new synthetic felt over the repaired area and install new shingles, matching the existing shingles as closely as possible.

If you notice buckled or uneven sections on your shingled roof in Chicago, addressing the problem early can help prevent further damage and potential water intrusion. Anchor Point Roofing can inspect the affected area and recommend the appropriate roof repair based on the condition of the roof deck.
