A research center created a hail storm inside to show insurance agents how much damage can cause all types of roofing.

Engineers put three different kinds of roofs on one building and tracked damage as 10-thousand hailstones hit the house.

"You can see some big dents on that one."

Rock Hill Insurance Agent Rett Rutland says even the more expensive type of roofing would need to be replaced after this mock hailstorm, "I would say anywhere from seven to 10 thousand dollars."

Scientists mixed tap and seltzer water to create realistic golf ball sized hailstones. The stones were then shot from a cannon at 80 miles an hour.

"I would have liked to see more impacts on the walls. I'm not sure we hit the skylights with 2" hail. That's what it would have taken to break the skylights." Said insurance agent Tim Reinhold.

After seeing the damage, experts said builders may need to go back to the drawing board to come up with a stronger material to handle the real deal.

Videos from the test are attached to this web story.
