This carport was difficult to put up......one of the arches that supports the metal roof was out of alignment and couldn't be fixed, and it turned out that the front metal pieces point in a downwards position but I can see that snow will just fall off them so maybe it's ok.....it's a bit long for me, 12 x 16 would have been ok and it might look better too....the anchoring system is ridiculous so we went with bolts from Home Depot that have 1850 lbs hold each.....and we put 10 of them in so it should be fine.......
