16×32 greenhouse with a dormer entrance, middle of the 32ft section out of plumb after attaching roof
Walls were all plumb as far as I recall when the valley and collar ties were all completed. The center of the long 32ft wall is bowing outwards, and the top of the front dormer section is leaning back some. I’m not sure if it’s the dormer pushing the back wall out, or if the backwall coming out is pulling the dormer with it. Any advice for straightening the wall up securely? I’m hoping the roof will not need to be removed. Walls are easy to shake around. All other areas of all walls are plumb, except the middle of the long, and the peak of the dormer front

What are you relying on for things to be plumb & square?
Have you checked every connection to the slab for dimensional accuracy? For level (i.e. is the foundation slab flat AND level)?
Did you temporarily brace every wall as it was erected to insure it was straight and plumb before moving on to the next?
Or did you rely on all pre-drilled member connections to pull the entire thing square & plumb?
Pic 3 shows that there may be 4 or more rafter collar ties missing.
Otherwise, there's not enough info to troubleshoot.
