Underlayment replacement
The secondary barrier under the covering
Decking is the structural sheet the roof covering is fixed to, and it is the thing a long-running leak destroys. Plywood or OSB that has been repeatedly wet delaminates and loses the ability to hold a nail, which means new shingles over it will not stay fixed. It is found during a repair rather than before — nobody sees it until the covering comes off — so it is usually a variation on the original scope rather than something quoted up front.
Conyers sits in the metro Atlanta hail and wind corridor. Spring storm season here does two kinds of damage, and only one of them is obvious. Straight-line wind lifts shingle tabs, breaks the seal strip underneath, and drops them back down looking untouched — the roof then leaks in the next storm from a spot that shows nothing from the ground. Hail does the other kind, bruising the mat under the granules so the shingle fails months later. Housing stock across Rockdale County skews newer and denser than most of the state, which means a lot of architectural asphalt in the 10-to-20-year band where the seal strip is past its best but the roof is nowhere near replacement.
Conyers has a population of about 17,305, and the housing stock here sets the pattern for what fails first on a roof.
Because it cannot be seen until the covering is lifted. Any honest quote prices decking as a per-sheet rate that applies only if it is needed, rather than guessing at it — and tells you before replacing more than was discussed.
Sheets that got damp once and dried quickly are usually fine. Sheets that have been repeatedly wet delaminate — the plies separate — and that is permanent. The test is whether it still holds a fixing.

You will get a straight answer on whether Conyers needs someone out today or whether it can wait — before anyone quotes you for anything.
