Deck Ledger Board Articles

A deck ledger board is used when attaching a deck to a house. It supports both the deck joists, as well as bolsters the framing of the deck. If your deck is attached to your house (and not a free-standing deck), you’ll also need deck flashing, which serves as a barrier against moisture from getting into the house through any openings made while attaching your ledger board.
