Roof Deck
The structural surface beneath roofing materials, typically made of plywood or oriented strand board (OSB) attached to the roof framing.
Why It Matters for Homeowners
The roof deck provides the foundation for all other roofing components. During re-roofing, damaged sections must be repaired or replaced before new materials are installed. A solid deck is essential for proper roofing performance.
