I am building a 12 x 16 shed and will need a ridge board about 2 feet longer due to overhangs. Is it possible to make this from 2 pieces without compromising the structure? should the joint fall at a rafter or between 2 rafters with a scab? Thanks
I would suggest between rafters .... near the center of length of the building.
When I needed a 24" ridge board, I used plywood on each side to splice two 12' 2x12s. Strung a line and braced the middle to eliminate the minor sag.
Started the rafters from both ends and did the center rafter pair last. When I removed the plywood, to do the last pair, the ridge board ends didn't move.
