AON•Aon study on roof ACV endorsements and storm claims
- Aon analysis found roof actual cash value endorsements cut average severe convective storm claim costs by about 30%.
- The study reviewed claims from seven regional insurers across 77 key storm events over the past five years.
- A review of 29 rate filings in storm-exposed states showed premium credits up to about 38% for end-of-life roofs.
- Aon pegged 2023-2025 U.S. insured severe convective storm losses at USD 164 billion, the three highest years on record.
- Catastrophe models often assume replacement-cost roofs, risking overstated modeled loss costs and probable maximum losses for hail-heavy portfolios.
