Roof Deck Rot Repair

Roof deck rot develops when moisture works its way under shingles, membrane, or flashing and sits against the wood sheathing long enough to soften and break it down. It often shows up as a soft spot underfoot, a sagging line along a roof plane, or a stain on an interior ceiling that keeps coming back. Left alone, rotted decking loses its ability to hold fasteners and support the roof covering above it, which is why homeowners typically address it as soon as it's found rather than waiting for the next re-roof.

Finding the Full Extent

Rot rarely stays where you can see it. Before any repair, we check the deck itself rather than guessing from the surface.

Wood Moisture Meters — direct readings on decking and framing to separate wet, compromised wood from wood that only looks discolored.
Handheld Infrared Cameras & Drones with Thermal & High-Res Cameras — thermal scanning that maps trapped moisture across the roof, including areas not safely walked.
Core Sampling Tools — test cuts that confirm how many layers are present and how far the wet insulation or decking actually extends.

Cutting Out and Rebuilding

Roofing Shovels, Tear-Off Spades & Pry Bars — old roofing and fasteners removed down to a deck we can inspect and trust.
Reciprocating & Circular Saws — controlled cutting that isolates rotted decking from sound wood.
Cordless Impact Drivers & Framing Nailers — new decking and framing fastened securely before roofing goes back down.
