Heres a pic to help u understand the seam I am trying to explain, this is on my 24' wide garage.I see your in Arizona so you don't have any snow or anything that would be a load bearing on top.So I would think that a 3 to 4" fall from 1 end to the other would be sufficient.This is what I would do ON A BUDGET and only my opinion only like I said I am no carpenter but have built a few structures and they r still standing in this 60 mph Wyoming wind snow infested state lol
