Make it the full width of the porch or slightly wider depending on your porch design.

Attach an awning ledger board to a wood siding house.

Predrill and sink 1 2 in. Rafters are placed on 24 centers and attached to the beams and settle joists are attached as needed image 1. In order to install the ledger board you usually need to remove the house s siding. The screws should penetrate the ledger the sheathing the house and go into a framing beam such as a floor joist or a wall stud.

Dia galvanized or stainless steel lag screws in every other joist space alternating up and down positions to keep the ledger from splitting. Find the wall studs or roof trusses that will have to support the ledger. The awning should be at least 7 to 8 feet above the ground or the patio. Attach 2x6 rafters to the house with joist hangers and or supported by the ledger board.

If necessary use a sliding bevel to determine angles needed where the rafters will meet the ledger board. Determine how high it must be to provide an adequate slope to the roof. Most house framing relies on building elements floors walls roofs being stacked one atop another. So make a mark above 7 to 8 inches and keep a minimum gap of 2 inches at one of the ends.

This is the only way to ensure the connection is water tight. If your siding is not beveled you can simply screw the ledger tightly to it. Once the ledger board is tightly fastened into place use a caulk gun to caulk all the seams between the ledger and the house with weatherproof caulk. Aluminum and vinyl siding can easily be removed with tin snips from an area one foot surrounding the ledger board location.

If you have beveled horizontal siding then use an inverted piece of siding as shown in the illustration here to create a plumb flat surface for attaching the ledger. Anchor deck joists to the ledger with joist hangers filling each hole with galvanized joist hanger nails rated for pressure treated wood. Also you need to keep enough open space approximately 3 4 inches above the top of the mounting bracket and ledger board. A ledger relies on the fasteners and strength of the wood ledger board and rim board of the house to carry the deck live and dead loads.
