VERY SEVERE HAIL
(VSH) Rated Roof Systems
When it comes to the protection of your building, your roof is the first line of defense against severe weather. There are few weather events more devastating to a roofing system than hail. In recent years, these weather events have become more severe across the country. FM Global is one of the most prominent property insurance companies and specializes in loss prevention and testing. FM Global has designated hail zones in the United States, classifying each zone based on the size of hail.
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.
CURIOUS TO KNOW more about hail damage?
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!
