the corrugate bends you run it longways front to back and bend it. do the ends first , and overlap it working your way to the peak. my friend has one of these with a rounded top peak. i will try to take a pic of it if you want me to so you can see what im talking about. just PM me with your email addy if interested. this garage started out as a curved top carport. now its got end walls and roll up doors on both ends on it.
