According to East Tennessee SKYWARN, “Hail is a form of precipitation that occurs at the beginning of thunderstorms. They consist of near spherical pellets of ice and snow, usually combined in alternating layers.” By this definition alone, you can already imagine what potential destruction Hail Spa can do to your home, specifically your roof. And, if hail can hurt your roof, just think how it can problems your vehicle. In fact, big hailstones that fall with force have been known to cause fatal harm to humans and animals.
