This Guy Slips off an Icy Shed
It is lucky this guy did not get hurt worse. climbing on icy roofs is not a god idea for anyone. Even trained roofing professionals will not get on icy roofs. There is nearly no way to try to stay on top of an iced over roof.
It is not advisable for people to climb, jump, skateboard, or Sled off of any roof while it is covered with snow or ice.
Maybe wait until the snow melts, but still wouldn’t jump off a roof.
