Sizing a ridge beam.

Our Rafter Design. In our rear rafter design, the birdsmouth cut is at both the top and bottom so that the entire weight is carried by the supporting wall as well as the ridge beam (see below). The front main rafter also has a birdsmouth cut at the top only. The bottom of the rafter sits directly on top of the wall top plate (see below).
