    Snow guards

    They break up the ice-sheets when snow / ice freezes on your roof. You can literally die if a sheet of ice falls on you during the winter, its a rather traumatic event. These guards help prevent this disaster, especially in areas where people tend to be walking around (aka: around homes).
