I used to live in MN. Softball sized hail does not care about the roof of your garage. After a few minutes of bombardment, something's gonna give. A softball sized hail stone will fairly effectively total a car in about 60 seconds. But don't worry, if you're out protecting your car, the one that gets you in the dome will make you forget you ever owned a S197.
We had some isolated area's in Vegas that saw golf-ball sized hail for about 5 minutes, Home Depot made a killing on rock shingles. The hail was pulverizing the hard shingles like they were candy. Great stuff for weathering wind and sand, won't put up with a good hail.
Neither will anything else...
