My college roommates and I did a fair amount of damage to our party houses and spent plenty of time on roofs... luckily, this never happened.

As someone who once got charged $300 to replace a doorknob by a college landlord, I can guarantee these California Polytechnic State University students... actually, their parents will be paying this off for the next 20 years. As you can see from the video, there were lots of college kids partying on roofs... the guys on the roof of the garage weren't so lucky.

According to a statement from the college, there were 10 injuries total, eight of which were minor and the other two were not life-threatening.
