 Hail Damage This episode of the Disaster Podcast featured a discussion about resilience and preparedness with guest Jake Sorber from the Insurance Institute for Business and Home Safety (IBHS). Jake explained IBHS’s research on severe weather hazards, particularly focusing on hail damage and wind-driven hail, which can cause significant additional damage to homes. He described IBHS’s unique ability to manufacture scientific ice spheres to accurately test building materials’ resistance to hail impacts. Becky DePodwin, our disaster emergency management expert joined the discussion along with our episode host, Jamie Davis.

Dr. Joe Holley and the team at Paragon continue to provide excellent and customized disaster response training to jurisdictions around the U.S. and internationally as well. Podcast Discussion Summary Disaster Podcast: Resilience and Preparedness Jamie Davis welcomed listeners to the Disaster Podcast and introduced the topic of resilience and preparedness. He noted that Sam was unavailable due to her recent move, but Becky was present as a guest. Jamie then introduced Jake Sorber, a research project scientist at the Insurance Institute for Business and Home Safety, who discussed his background in atmospheric science and his current work studying the effects of hail and wind on residential homes and commercial structures. IBHS Structure Testing and Mitigation Jake explained how IBHS, an insurance industry organization, was founded to conduct full-scale testing of structures to better understand vulnerabilities to severe weather events like hurricanes, hail, tornadoes, and wildfires. He described a specific hailstorm in Rock Hill, South Carolina in April 2024 that demonstrated how wind-driven hail can cause damage beyond rooftops, including siding and windows, which can lead to water intrusion and significantly increase losses by 2-4 times. Jake emphasized the importance of identifying “damage amplifiers” – structural elements that fail and cause disproportionate damage, which helps in developing mitigation strategies. Hail Risk and Insurance Insights Jake explained that there is limited historical data on wind-driven hail frequency, and IBHS is developing an instrument to measure impact angles and forces during their annual hail field campaign. He noted that while storm severity has shifted, socioeconomic factors like urban sprawl and increased building costs have had a greater impact on insured losses than weather changes. Jake mentioned that severe convective storms now cause annual losses of $40-60 billion, up from $15 billion historically, primarily due to increased population in hazard areas rather than increased weather risk. Hail-Resistant Building Materials Assessment Jake explained that hail-resistant building materials do exist and are assessed based on IBHS’s testing protocol, which involves simulating hailstorms in a lab. He mentioned that synthetic composite roofs like F-Wave and metal roofs perform well against hail damage, though metal roofs may have cosmetic issues. Jake noted that while some materials like synthetic composites show no damage after multiple hail exposures, the distinction between cosmetic and functional damage is important to consider. Residential Building Weather Resilience Jake from IBHS discussed residential building resilience against severe weather hazards. He explained that while completely hazard-proof homes don’t exist, building materials and construction methods can significantly reduce risk, particularly in high-risk areas like Tornado Alley. Jake described IBHS’s work on developing resilience scores for structures and their unique ability to manufacture hailstones for testing building materials. He also covered wildfire preparedness, emphasizing the importance of defensible space and structure separation. The discussion concluded with information about IBHS resources available at ibhs.org. Wrap up and updates The team went through contact information and the team encouraged listeners to stay safe. The group discussed the role of specialized training, with Jamie highlighting the sponsorship of the Disaster Podcast by Paragon Medical Education Group.
