Roof Decking Replacement in Redondo Beach, California

The roof decking is the plywood or OSB that sits on top of the framing. It is the surface the shingles attach to, and it is the first thing the water damages when the roof leaks. Roof decking replacement in Redondo Beach removes the rotted wood and gives the roof a solid base again.

Signs Your Redondo Beach Roof Decking Is Damaged

• Soft spots in the roof — the deck is rotting from the moisture
• Sagging roof line — the deck has lost its strength
• Water stains on the attic deck — the moisture reached the wood
• Visible rot or mold on the sheathing — the wood is breaking down
• Algae or moss damage letting the water in — the deck below is taking the damage

Why Redondo Beach Roof Decking Fails

The water is the cause. The algae-damaged shingles and the corroded flashing let the moisture reach the deck. Over time, the coastal damp rots the wood and the deck loses its strength.

The algae adds to the problem. The growth on the shaded slopes holds the water against the shingles, and the moisture works its way to the deck below.
