The roof framing is pretty easy with the flat roof. We added two extra plates to the front (high) side wall. Then we just set roof rafters the same way we did the floor joists. The rafters project on each end for weather protection at the doors.

If you were building a gable (this ^ shape) roof you would put down loft joists, then frame up the end walls and have them support the ridge board for the roof rafters. (This is described in the Plans Kit.)
