Snow on the Roof?

I was sitting in my room waiting for some people from class to show up at our apartment when I heard a 'thud' outside my window. As I opened the curtains I see this taking place on the apartments across from ours. This poor guy was trying to shovel snow off the roof and apply salt to try to melt some of the ice. I don't know how he's still alive. This was clearly an immanent danger situation and the last thing I wanted to do was yell out at him, "Hey!" and startle him off the ladder. So instead, I took his picture. I might turn it into the apartment complex.
