S5E11: Not All Hail is Created Equal: The journey to understanding hail damage
When it comes to hail damage, size is only part of the story. Two hailstones of the same size can produce very different outcomes depending on the roofing material, its age and condition, and the strength and structure of the hailstones themselves. In this episode of Disaster Discussions , IBHS Managing Director of Atmospheric Science Dr. Ian Giammanco, Research Project Scientist Jake Sorber, and Central Michigan University Ph.D. student and IBHS Summer Fellow Sabrina Servey recap the 2026 IBHS hail field deployment across the Plains. They discuss the partnership behind the research, the challenges of chasing hail during a drought-affected season, and what the team learned from 10 intensive operating periods. The conversation explores new field capabilities- from deployable trailers and roofing-panel exposures to hailstone strength testing and impact video- and how these observations help connect controlled laboratory testing with the complex conditions of real storms. Hear what researchers are learning about hailstone characteristics, hail concentration, and the performance of asphalt and composite roofing materials- and the questions that remain as IBHS works toward more realistic, actionable understanding of hail damage and how it impacts both roofing materials and the building envelope.
