roof decking

Boards beneath shingles

Roof decking is the structural layer of boards or panels that sits on top of a building's rafters or trusses, forming the base to which roofing materials are attached.

It's typically made of plywood, oriented strand board (OSB), or planks, and provides the solid surface that supports shingles, tiles, or membrane roofing.

The contractor found water damage in the roof decking and had to replace several sheets before installing new shingles.
