Hail storm system resources
GAF hail storm systems
Before the storm hits, count on FM-Approved GAF hail system solutions1 to help protect your investment. The cost of a hail storm can cause billions of dollars in damage — and experts predict the frequency of storms to increase. According to a 2018 NASA study, steady increases in carbon dioxide in the atmosphere may significantly increase ocean temperatures, which in turn may increase the frequency of extreme storms by as much as 60% by the end of the century.2
Protect buildings, customers, and your bottom line
When you purchase or specify a GAF hail system solution, even the toughest curveballs nature can throw won’t stand a chance. GAF hail system solutions meet FM’s Very Severe Hail classification requirements — the most stringent roofing impact resistance standard.3![](https://www.gaf.com/-/media/featured-content/feature_severe-hail-systems.jpg?h=663&w=1272&la=en-US&hash=6B1C5E3C1781CBB4FF1DDE92707B58D710FC6973)
