That is a lot of icy crap! Steve said the only problem with getting the deflectors for the roof is that they will catch a lot of leaves if you have trees nearby He put a metal roof on the pole barn a few years ago.
I think we have only gotten one ice storm that rolled off the roof like that. If we got them often we would get the deflectors.
I hope you don't get anymore bad weather this year! You need a break!
