Roof Decking Replacement in Milpitas, California

The decking is the plywood or OSB under the shingles. It carries the whole roof, and when it rots, the shingles sit on a weak base. Roof decking replacement in Milpitas means putting a solid layer back under the roof so the new covering lasts.

Signs Your Roof Decking Is Failing

• Sagging or wavy areas on the roof surface
• Soft spots that give when you press on them
• Dark stains on the underside in the attic
• Shingles that buckle or curl over a weak section
• A leak that keeps coming back after the repair

Why Decking Rots in Milpitas

The decking rots where the water gets in and stays. In Milpitas, the winter rain works through the worn shingles and the cracked flashing, and the shade keeps the wood damp.
