Well, my long title is sort of self explainatory... We need to do a full rip and replace of our roof, however, we also have a sunken corner of the kitchen and a bowing foundation on the north side. I am just looking for advice about order of operations. My gut tells me to do the jacking and leveling first, reenforce the foundation, then do the roof. My thought is that if I do the roof first, it might be disturbed enough during the leveling process to cause it to shift and leak. Any advise?
