I looked at a remodeling job yesterday and I am concerned. This house is a simple 22’ x 32’ gable roof 12/12 pitch, 2×6 rafters 16†o.c. with a 1×10 ridgeboard. The ridge board has 2 splices. The contractor braced the front roof and tore down most of the back for a 24’ wide shed dormer.
The problem is the dormer section, now has about a 3/12 pitch. Saltbox shaped. The new 2×6 rafters are attached to the old ridge board with hangers. I told them they need to put in ceiling joists from the top of the new wall and tie them into the front rafters. They wanted to leave it open and hang a drop ceiling. I’m unsure if this is even expectable. There was no permit pulled yet, I’m wondering what an inspector will say when they do.
See the sketch I attached.

I did the same thing in my house a few years ago. I put a wall up that formed the entry way to the bathroom, and I balloon framed it all the way to the underside of the rafters. That way I had a cathedral like ceiling in the bathroom. I never had a problem. The side wall framing looks a little funky though. The wall I put up acted as a header to keep the rafters from sagging. I never had any other problems......
