This is some of the biggest hail to ever hit Louisville Kentucky.
Hail this size is liable to cause damage to cars, roofs, windows, siding and more.
The Caption of this video states :
“Hail picked up near Churchill Downs. Just shy of being the size of a tennis ball.”
That is some pretty big hail, I would think most roofs will need replaced after that kind of damage. If you have no have your roof looked at by a professional you probably should call a roofing company to inspect your home.
