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
Why it matters: when an old roof comes off, the deck is exposed for the first time in 20-30 years. Hidden rot, rusted nails, or sheathing that has bowed all show up at that moment, and they all need to be addressed before the new roof goes on. We strip every roof down to the deck and inspect it on every job. That is how the new roof ends up on a clean, structurally sound surface instead of on top of problems we could not see.
