Severe thunderstorms frequently are accompanied by hailstorms. As population density has increased and spacing between residential and commercial buildings has decreased in many metropolitan areas, there has been rapid growth in the number of hailstorms that cause hundreds of millions of dollars – or more than a billion dollars in damage. Property owners pay for this damage in several ways, including through inconvenience and being responsible for insurance policy deductibles when losses occur. Fortunately, impact-resistant roof covers can reduce losses and associated property ownership costs.
