Texas Hail Study Summary

Download the Texas Hail Study Summary.

Like most residents of the southern U.S. Great Plains States, those who live in the Dallas-Fort Worth metropolitan area can expect damaging hail of one-inch diameter or greater every three to five years on average. While hailstorms are generally not a great threat to human life, the extensive damage they cause to automobiles, crops, roofs, etc. carries a multi-billion dollar annual price tag. A large part of this cost is due to damage to residential roofs and their appurtenances. In order to further its hail mitigation efforts and provide more insight into typical costs associated with hail impact on various roofing types, the Insurance Institute for Business & Home Safety (IBHS) conducted a study – using insurance claims data from one particular hailstorm – to investigate trends in insured losses and damages to single-family homes with respect to roof type, hail size, impact-resistance status, and other variables.

Scope and Objective

This study focuses on insured losses and damages to single-family homes located in the vicinity of Dallas and Fort Worth, Texas, following a hailstorm on April 5, 2003. Data was compiled from several IBHS member insurance companies and analyzed in an effort to determine patterns in insurance claims and payments with respect to hail size, roof type, impact resistance status, and home value.
