Hello, thanks for taking a look at my post.  I’m framing a gable roof with a span of 24′ for a guest house project.  I’m lapping the 2×10 ceiling joists over an interior load bearing partition (see attached diagram).  My plan is to overlap the joists 18″ on the partition wall and insert a 2×10 section between the ceiling joists to add an offset to the 2×8 rafters so they will directly line up across from each other at the ridge.

QUESTION: Does this seem like a good practice?

Thanks in advance for your input.
