Yeah prebuild as much as you can on the ground is the way to go especially if you're kind of chicken of heights like me (Which is weird considering what I do for a living)

When I built my shop 15 years ago now (Wow!) with a bonus room inside the upper trusses I set it all out on a level surface next to the walls and prebuilt it all in three sections. Once it was ready and the big picker truck showed up we had the roof sitting on the walls in about 2 hours. It was really smooth except for me sweatily second- guessing my measurement abilities while it was going up in front of all my helper buddies, but it worked out.

Course you have to have the room for that and I was lucky there.

This shop we did a few years ago was one of my favorites as is the guy who I built it for.  11 foot walls on top of a 4 foot foundation and it was roughly 32 feet by 50 something with enough room for him to park his coach.  Built the 2 hip roofs for the end first which brought me close to my concrete height and then built all 4 walls on top with the 2 long ones being exactly in place.  I think my son and I were about 3 hours with the crane guy also helping and all the trusses were stood and the plywood was sitting on the end of the roof for us.  Great memory.  I like it to be quick when I'm 15' off the ground.  Not scared but I'd rather be on the ground doing the same thing.

I agree. The only reason I didnt sheet the walls first was because I closed it in with tongue and groove boards and wouldve been waaay too heavy to lift, especially for just 2 guys. Im all over the truss company, but theyre so backed up that Im just another delivery to them. This is what I do for a living, so Ive been pulling as many strings as I can. As for the weather, I think my lucks about to run out.

 get those guys that put up tents for weddings. They would not be buzy this time of the year then you could finish it of out of the weather

What R value for ceiling insulation? Im doing mine this spring when I find some on sale. This is for my separate garage, 6 inch walls are insulated.
Thanks,

 Id say a minimum of R28 but if not too pricey go up to R40.  Sometimes a more reasonable route is to go blown insulation if you have a flat ceiling and arent going to be storing anything up there. To me ceiling insulation helps the most of all as in the summer it also helps keep you a little cooler. Toughest part in a garage is the doors as their R value is typically quite low but they have made some pretty good improvements. My doors are 28 years old and about R2 at the most.
