Roof Decking Replacement in Newport Beach, California

The roof decking is the wood that sits between the rafters and the shingles. When the decking rots, the roof loses its strength and the shingles lose their support. Roof decking replacement in Newport Beach restores the structural layer of the roof.

Signs Your Newport Beach Roof Needs Decking Replacement

• Soft spots when walking on the roof — the decking is rotted underneath
• Sagging areas on the roof surface — the decking is losing its strength
• Water stains on the attic roof sheathing — the moisture has reached the deck
• Daylight showing through the gaps — the decking has pulled apart
• Mold or rot smell in the attic — the moisture is trapped in the deck

Why Newport Beach Roofs Need Decking Replacement

The winter rain is the main cause. A leak that goes unnoticed for weeks or months lets the water soak into the plywood deck, and the plywood rots from the bottom up.

The coastal moisture works the other way. The damp air from the marine layer condenses on the cold roof deck and rots the sheathing over time.
