Warped Decking Weakens Your Roof

10 September 2026

ROOF STRUCTURE

Decking warps when moisture gets trapped under shingles or in the attic, often from poor ventilation, ice dams, or long-term leaks. Warped decking creates an uneven surface that breaks the shingle seal and lets water get in faster.


Warped decking is a structural problem, not cosmetic. It causes shingles to lose their nail grip, opens gaps for water, and can spread rot to rafters if ignored.
