TL;DR
Decking replacement is the substitution of rotted, delaminated, or broken roof sheathing panels discovered once old shingles come off during a reroof. Contracts handle it as a unit-price allowance, a few sheets included, then a stated dollar amount per additional 4x8 panel of plywood or OSB, because nobody knows the deck's condition until tear-off exposes it.
What it means
Decking replacement is the substitution of rotted, delaminated, or broken roof sheathing panels discovered once old shingles come off during a reroof. Contracts handle it as a unit-price allowance, a few sheets included, then a stated dollar amount per additional 4x8 panel of plywood or OSB, because nobody knows the deck's condition until tear-off exposes it. Soft spots underfoot, sagging between rafters, and dark staining around old leaks are what crews look for, and photos of the bad panels before covering them should accompany any added charge.
