Lead Contacts

Thornton Tomasetti delivers industry-leading solutions for hailstorm damage assessment, leveraging advanced AI technology, forensic analysis and a deep understanding of roofing materials to support commercial and residential clients across the U.S., particularly in high-risk areas like Texas, New Mexico and Denver. 

With commercial insurance claims from hailstorms ranging between $8 to $14 billion annually, hail is one of the leading causes of property damage.
