Started here
than after about 10 times more tear off then we could have imagined got to here...
notice the multiply siding choices, clapboards then shakes then vinyl, roof was 3 layers of asphalt then shakes. Thought the floor was alright oh god not a chance. The middle steep part thats gone here was double board when they added the 6 feet with the hip they made all that area underneath open kitchen then dropped a drywall cieling. they chopped the old gable wall off above the ceiling no header nothing. We took top off the gable and the floor dropped like 5 inches.

So when we got the floor opened we found hardwood over subfloor over 2x4 sleepers trying to shim the original bow, then subfloor then 2x6 joists spanning like 14 feet then 2x4 dropped cieling then drywall.
It was a hoot trying to keep the kitchen ceiling from falling while we ran new 2x12 joists then tied the cieling back up.
Thank god got the bastard gable from our 8/12 into their 12/12 sided and the shingles on today. And yeah without fail its was out of square 6" on the diagonal.
