A ledger board is an essential component of a deck structure. It is a long, horizontal board that is attached to the house’s exterior wall, parallel to the ground. It provides structural support for the deck by connecting the deck to the house, which transfers the weight of the deck and its occupants onto the house’s framing.
The ledger board is usually attached to the rim joist of the house frame with galvanized lag screws. It can also be attached directly to a basement wall with galvanized expansion anchors if it is too low to meet up with the house framing. In either case, it’s important that the connection is extremely solid. A connection to just the exterior siding, for example, will not be strong enough to support the weight of the deck.
Once the ledger board is level and securely fastened, the deck joists can be attached to it to create a strong and stable deck structure. The ledger board should be made from a durable material. At Fence-All, we use pressure treated 2x8s.
It’s important to note that ledger board installation can be complex and should be done by a professional or experienced DIYer with knowledge of local building codes and safety precautions. A poorly installed ledger board can result in a deck collapse or other safety hazards.
