The average lifespan of some roofs is 20 years, however roofs in severe hail-prone areas often must be replaced every seven to 10 years. An IBHS review of research and testing related to hail damage indicates that there is considerable variation in the impact resistance of different types of roof coverings.

IBHS research found there is considerable variation in the impact resistance of different types of roof coverings. Lab tests and field observations indicate that most commercial roof coverings are not typically damaged by hail less than 1.25 in. in diameter, however, 3-tab asphalt shingles may be damaged by hail as small as 1 in.

2015 IBHS Hail Field Study

IBHS is continuing a multi-year, major field research effort started in 2012 to study hailstorms with the goal of reducing property losses and improving weather forecast models and radar detection of hail. As part of this effort, IBHS is studying hailstorms in the Central Plains region in an attempt to better understand the characteristics of damaging hail, which depends on size, shape, density and hardness of hailstones. The field study provides valuable data and insights for shaping ongoing work at the IBHS Research Center.

Scientists and technicians recreated the first-ever, full-scale hailstorm in the IBHS Research Center’s large test chamber. Researchers created more than 9000 hailstones that were used in the demonstration and were able to closely mimic hail conditions present in a typical supercell thunderstorm that produces hail. IBHS engineers worked from 2010 to 2013 to develop the test protocol and customized equipment that allowed scientists to conduct full-scale hail testing.
