Identify and Assess Damaged House Ledger

What happens here

During the initial demolition and framing, a significant issue is identified: the house's existing ledger board, where the new deck is to attach, is severely rotted. A worker points out that the original construction utilized non-pressure-treated wood for the bottom plates, rim joist, and joists. Coupled with improper flashing, this allowed water to penetrate the structure, leading to extensive decay. The damaged area affects the structural integrity of the house's wall where the deck is meant to be secured.

Goal: A severely rotted section of the house's existing ledger board is discovered, caused by inadequate flashing and non-pressure-treated lumber.
