If the corrugations are run horizontal, especially near the top wont there be an issue of it holding snow, and even rain. Rain would leave little puddles in the valleys of the corrugations, the standing water will be a breeding ground for skeeters, alge would grow, and over time the water will find a way thru the seams. Sticks and other debris would want to stay up there too. The snow would just keep building and not be able to slide off. I would be worried about buildup exceeding the weight capacity of that light structure.
You just know that I can not resist sending a good snow there once in a while......... OK back to my corner for another bout of double secret probation......
