There has been a "belly" in the porch roof ridge line for as long as I have owned this house (10 years). I am finally doing something about it as I prepare for a new roof, soffits, facia and gutters. I took more than half of the sag out today. I still have more jacking and bracing, but I feel good about the progress.
Certainly I have lots of experience straigtening structures like this. I remember my Uncle and my Father straigtening the collaped roof on the laundry shed near Bridgton, Maine in the 60s. The first one I did was a garage in the late 80s. I am using the 20 ton hydraulic jack I purchased in the mid 90s to jack and straighten the house I restored in Victor NY. I can't say I like working in attics and crawl spaces. I like the value it adds when complete, since it is easy, but scary and complicated for most. It is "pure" work.
