Help please, we're struggling to find answers. All advice welcome!
DIY Plan - Support the original rafters (in pic) and add new straight (as possible) timbers for plasterboard to fix to.
Problem: There is about an inch and 1/2 bow in the middle of the rafters (along and across).
Recommended approach (by a friendly roofer): drop the new rafters at the top to create a new straight line and add support timber underneath.
Our concern: If the new straight rafter line drops below the bowed rafters by a significant distance, we could lose space in which to fix the new and old rafters together (at the top like in 2nd picture).
Our query: Will this reduce the support the new rafters will provide?
