How do I Know if my Roof Decking is Rotted?

Identifying rotted roof decking early is essential to preventing serious structural failure in your home. Because Vancouver’s high humidity and rainfall can quickly deteriorate the plywood or OSB sheathing beneath your shingles, we recommend looking for these critical warning signs:

• Sagging or Spongy Sections: If you notice dips or soft spots on the roof surface, the decking has likely lost its structural integrity and load-bearing capacity.
• Ceiling Water Stains: Dark, damp stains on your interior ceilings or walls are often a direct indicator that moisture has fully saturated the sheathing.
• Attic Indicators: Look for dark, damp insulation, visible mold growth, or a persistent musty odor in the upper floors or attic space.
• Exterior Red Flags: Peeling interior paint, warped shingles, or shingles that have detached (often because the rot has caused nails to back out) are clear signals of water damage.

In our over two decades of local experience, we have found that even minor leaks can mask advanced deterioration. Because rotted decking compromises your roof’s ability to handle snow and wind loads, professional intervention is necessary to restore safety.
