Roof Decking Replacement in Fountain Valley, California

The decking is the wood under the shingles, and it carries the whole roof. When the moisture from the leaks and the marine layer gets in, the plywood rots. Roof decking replacement in Fountain Valley means replacing the weak wood before the roof sags or fails.

Signs Your Fountain Valley Roof Decking Needs Replacement

• Sagging sections of the roof — the decking has lost its strength
• Spongy spots when you walk the roof — the plywood has softened
• Water stains on the ceiling — the leak soaked the decking
• Visible rot at the eaves and the valleys — the water pooled and soaked the wood
• Gaps between the decking panels — the plywood has warped or shrunk

Why Fountain Valley Decking Needs Replacement

The old leaks are the main cause. The tract roofs have been through decades of winter rains, and the small leaks soaked the plywood. The decking rots from the inside out.

The marine layer adds the moisture. The fog keeps the attic damp, and the plywood stays wet. The damage is hidden until the roof is inspected.
