These zones are used when designing, specifying and constructing roof systems to ensure they meet
the criteria to withstand impacts from the designated hail size. The geographic areas have increased
year-over-year according to FM Global. Roof systems need to be designed and installed with resilience in mind.
Commercial construction throughout the world demands resilient buildings. Resilient buildings are buildings that resist and recover from extreme exposures and also address climate change. This video focuses on extreme hail impact exposures for commercial roofing, specifically hail damage.
Did you Know? The largest hailstone recorded in the United States was documented in South Dakota in 2010. The hailstone measured 8" in diameter, over 18.5" in circumference and weighed almost two pounds! That's the size of a volleyball!
