Why decking fails
- Years of ice dam leaks at eaves
- Failed flashing at chimneys and valleys
- Original boards thinner than modern code
- Animal damage or prior overlay that hid rot
How we handle it
We probe from the attic when access allows and note suspect areas before tear-off.
Proposal language typically includes a per-sheet or per-square-foot rate for plywood or OSB replacement — you approve before we expand the scope.
What "float" means
Weather float is calendar time. Decking float is material and labor if soft spots appear.
Both should be clear in writing so a low bid that assumes perfect decking is not the real comparison.
