Can you attach a ledger board to rafters?
Attaching Rafters to a Ledger Joist hangers can hang rafters from a ledger, but, for sloping rafters, notch them or use special rafter hangers. If rafters will sit on top of a ledger, attach them with seismic anchors as you would attach rafters to a beam.
How do you attach a ledger board to a roof?
Attach the ledger with 1/2-inch-diameter lag screws or bolts every 16 inches (or as specified by local building codes). Slip stainless-steel washers between the ledger and the siding to allow water to flow behind the ledger. If you can’t get behind the joist to cinch down nuts, use lag screws.
How do you find studs on a ledger board?
Use a good quality stud finder or rap firmly on the wall and listen for a solid sound, indicating a stud is beneath.

Another clue is the location of outlets and switch boxes because one side should connect to a stud.
How do you attach a ledger board to a house for a porch?

How are rafters attached?

How do you nail a Birdsmouth rafter?
Drive a toe nail on each side of the rafter just above the birdsmouth into the top plate. Adding more nails than that may split the lumber and weaken the birdsmouth.

How do you attach a ledger to siding?
Attach the ledger with 1/2-inch-diameter lag screws or bolts every 16 inches (or as specified by local building codes). Slip stainless-steel washers between the ledger and the siding to allow water to flow behind the ledger. If you can’t get behind the joist to cinch down nuts, use lag screws.
Do you need to flash a patio roof Ledger?

How is a ledger connected to a house?
The strongest ledger connection relies on bolts that run through the ledger and the house sheathing and rim or band joist and then are fastened with nuts and washers affixed from the other side. When access to the other side is unfeasible, use lag screws with washers instead of bolts, as shown in the illustration.
