I’m looking for advice on framing a saltbox roof. This would be all new construction. Picture a gable roof with a shed roof addition. The shed roof joins the main roof over a load-bearing interior wall on the 2’nd floor. The long side of the roof (regular roof + shed roof) is longer than a continuous rafter will span so the logical thing to do is join the rafters over the load-bearing wall. The question is: what are my options for doing this? I’d like to not have to offset the rafters for the shed portion of the roof – these will be cathedral ceilings under the roof slopes so I’m looking for ways that won’t complicate the drywall installation and will make for a neat job!
Thanks for any thoughts!

SInce you've got a load-bearing wall to make the split over, offsetting the joists won't affect the drywall (not that it'd be that big of a deal anyway). Another option would be to use I-joists for the rafters, which would allow for a continuous run from ridge to fascia. They're also available in deeper profiles, allowing for more insulation in the cathedral ceiling.

I'd try to use TJIs
for solid lumber you could overlap, but you could also butt joint on the load bearing wall ( make darn sure it is designed and built to be load bearing) and use sisters to tie or use mending plates or strapping at the joint as well as hurricane ties to the wall.
