Looks great! It is very much like a bit smaller version of mine. What are the outside dimensions of it again?
And how tall is the peak of the roof on the ends?
Mine is about 25' tall and I had to do a ton of bracing afterward because the wind would move the end walls in and out several inches. Of course I had garage door right in the middle of those walls which made things difficult.
Good luck roofing, just had mine re-done as well. I hired it out!!
