Short answer

Rotten or soft decking is replaced during installation and billed per sheet — ROOF.CLICK flags it up front and documents it with photos.

In more detail

You can't nail a good roof to bad wood. During tear-off, any damaged plywood or OSB is replaced. This is a concealed condition that can't be fully seen until the old roof is off. A reputable contractor shows you photos and a per-sheet price before replacing it.
