My biggest concern would be snow melt that re-freezes to ice at the bottom of the snow load. Ice is much heavier than snow.
While ice is heavier than snow by volume, you don't increase the total amount of water via snow melt. If it's snows a foot and melts to an inch of ice, it's the same volume of water and the same weight. It's just changing from snow to water back to ice - but you didn't add any additional water or weight. Reminds of an old riddle - which weighs more, a pound of feathers or a pound of lead?
