I am building an enclosed porch and just now attaching the rafter header to the house. The current siding is wood shingle. It will make a mess of the shingle above and below to remove a row to attach the header. Can I just nail/bolt the header right to the siding? Behind the siding is
1/2" ply and then upright 2x4's. I plan to used galvanized 4" nails and try to hit as many of the 2/4's as possible.Is this ok to do? My guess is that the rafter header is not bearing a big amount of weight even under snow load, but rather the weight goes down to the beams on the front of the porch, and pushes back against the side of the house, rather than directly down on the rafter header.
