i saw a article in fhb a couple years back on building a complete roof structure on the ground and then craning it into place.i’m getting ready to do a 12/12 pitch roof on a 2 story and would feel much better about being on the ground to sheet and shingle than going up and down the ladder 500 times!does anyone know what issue that fhb had this article in,i’d like to read it again and have it in my hand,because everyone i’ve mentioned it to their eyes glass over and they get this little grin on their face like i’ve dropped off the deep end.by the way the structure would be 16 wide 39 long,12/12 pitch,i’d guess the weight would be around 10,000lbs.thanks larry ‘i’m not crazy,just a little unwell”

Hey Larry
Check out 140 or maybe it was 141. There was one picture of a roof section going up on a crane. It wasn't papered or shingled,but, it may have had a fair amount of sheathing on it.
I remember a post on the old board from a guy "Framer Pa", I think. He had pictures of a sheathed and papered roof going up. Heck it may have been shingled as well.
Your roof sound like a good candidate for at least building and sheathing on the ground in two or three sections. I could tel you how, but, then I may have to kill ya!:D

Any reference to a death threat is purely a joke. No harm is meant or implied to come to the original poster.
I've done probably 40 houses that way. We built the roofs anywhere we could make a flat space. We left off the first row of plywood on each side so we could get to the plates. We sheathed the gable ends and when the crane came we lifted the roof up until it was hanging about 7 feet off the ground and then ran the soffit screen and soffit then set the whole thing on the walls. When the crane operator had it sitting on th eroof 4 of us would climb up and sit on the plywood on each corner. When we were ready the crane would lift the roof just enough to take the weight off and the 4 of us would shift the roof around by pushing on the plates with our feet. Worked like a charm. As soon as it was resting on the plates several of the guys would start nailing the clips on. The rest of us would unload the rest of the plywood and shingles onto the roof. These houses were 2 story on pilings so it was a long way to the ground. Much easier to work low. The roofs we did were usually only 4/12 pitch, 24' wide and 36' long so yours would be a bit tougher. I wish I had pictures because it was a traffic stopper. I'd do it again but I think I'd leave the soffit work until later. My faith in cranes and cables has taken a few hits since then.
It was an article by Rick Arnold and Mike Gueritn (sp?) try # 99??
