Abstract: Green roofs can significantly reduce, and in most cases eliminate, the damage and cost of roof repairs caused by hailstorms. Green roofs act as a buffering layer of substrate and plants, absorbing the destructive impact of hail hitting the surface during a hailstorm. Anticipating severe weather and implementing cost-effective protection strategies, such as green roofs, can result in significant savings for property owners and insurance companies. This study demonstrates and quantifies the advantages associated with the use of green roofs to prevent hail damage and associated cost benefits. Testing and data collection in this study were based on the current recommended testing method, UL 2218 Standard for Impact Resistance of Prepared Roof Covering Materials, testing impact resistance by dropping steel balls onto the roof surfaces from various heights.
