How flood endorsements can help close the US flood protection gap

Flood risk is expanding beyond traditional high-hazard zones, yet fewer than 4% of US homes have flood insurance. Insured flood losses reached $319bn from 2000-2024, with uninsured losses over $1.58tn. Flood endorsements added to homeowners policies offer affordable supplemental coverage, especially for inland areas, reducing costs and complexity. This approach helps close the protection gap by making flood insurance more accessible outside designated flood zones.
