Invariably when I'm working on an older house remodel, I can't achieve a flat ceiling in the interior and always end up with a portion of sloped ceiling along the exterior walls. (See attached pic.) My interior ceiling height is correct, the height of the windows is correct, the roof fascia and soffit heights are correct. This particular house is from 1948. Did they use smaller rafters? Different framing methods? Any help is always appreciated...thanks.
