Top 10 flood insurance companies in the US

Flooding is the most common and costly catastrophe insurance claim in the US, causing billions in economic losses every year. According to the National Flood Insurance Program (NFIP), 90% of natural disasters in the country involve flooding. 

There’s no coverage for flooding in standard homeowners or renters policies or most commercial property insurance policies. Coverage is available in a separate policy from the NFIP and a few private insurers.
