Pretty nice looking shelter. Looks like cedar to me.
I did the same thing at my old house shortly after getting a tractor. Worked great for me. I did learn that putting up metal roofing in the rain is no fun though. Even with just a light drizzle, rivers were running off the roof onto me and my ladder.
Maybe should of made it higher If you were to catch tractor fever a bigger tractor may not fit. Just kidding looks great.:cool2:
