The Amazing Sideways Icicles

My house has a metal roof. I don't think I've ever lived in a place with a metal roof, but many houses in areas with a lot of snowfall have them. I'm discovering a curious phenomenon occurs when snow that has built up on the roof starts to slide off. I'd expect it to project off the eaves at the same angle as the roof, then fall off in chunks as the weight becomes too much to hold it suspended in midair. Instead, it droops and curls under, hanging in this odd shape for a very long time.

In the meantime, icicles form. As the snow makes its curl, the icicles angle until they are hanging sideways. How weird is that?
