Condition, scope & system planning
Concealed wood conditions should be documented and priced before the new roof covering hides the repair
Roof decking supports the underlayment and roof covering. It can be damaged by long-term leaks, condensation, insects, impact, poor ventilation, failed flashing, or previous installation work.
Some damage is visible from the attic or roof surface, but full extent may not be known until old materials are removed. Written unit prices for plywood, planks, fascia, or related repairs help reduce surprises.
Deck replacement should address thickness, material, fastening, framing support, openings, transitions, and local code requirements. Simply covering deteriorated wood can compromise fasteners and the new system.
Fascia and soffit damage may be related to roof-edge leaks, gutters, drip edge, animals, rot, or ventilation. These components should be coordinated with the roofing and gutter scope.
Ask for photographs of concealed damage and completed repairs, along with quantities and added cost, before the area is covered when practical.

Questions homeowners often ask
Can roof decking be repaired from inside the attic?
Some limited work may be possible, but roof-covering removal often provides better access. The method depends on location, framing, safety, and the full assembly.
How can I budget for hidden wood damage?
Ask for unit prices and an authorization process in the contract. Existing leaks, attic stains, soft areas, and previous repairs may help estimate risk.
Does all stained decking need replacement?
Not necessarily. Replacement decisions should be based on strength, moisture damage, delamination, rot, fastener holding, code, and contractor evaluation.
