Rising Flood Risks and Insurance Gaps in the U.S.
Floods are among the most frequent and costly natural disasters in the United States, with damages exceeding $8 billion in 2024, based on Federal Emergency Management Agency (FEMA) data. Remarkably, $3.8 billion of this damage occurred in areas not designated as high-risk. The U.S. Flood Risk Index by Fathom predicts a 72.6% surge in average annual exposure to flood risks by 2050 compared to 2020.
Louisiana faces the steepest increase in flood risk, with only 23% of homeowners possessing flood insurance. Florida trails with under 15% coverage, while in states like South Carolina and Texas, less than 7% of homes are protected against flooding. Despite the escalating flood risk, insurance uptake remains insufficient, suggesting that 97% of the U.S. population might be at flood risk by 2050.
Underinsured States Face Rising Flood Risks
Insurance.com reports highlight states experiencing rapid rises in flood risk alongside substantial flood insurance gaps. By 2050, Louisiana is projected to see a 147% increase in average annual losses (AAL). Florida follows with a 73.6% rise, and South Carolina with 58.4%. In Texas, a 46.6% increase in AAL is expected, with 56% of 2020 flood losses outside Special Flood Hazard Areas (SFHA), underscoring a critical coverage gap where only 6% of homes had flood insurance in 2026.
Gulf and Atlantic Coast states report the highest projected AAL increases. Fathom data indicates substantial population exposure to floods in states like Iowa (276%), Georgia (236%), and North Dakota (221%).
The Impact of Climate and Infrastructure on Flood Insurance
Flood insurance penetration varies widely across states. For example, Florida accounted for $13.83 billion in claims under the National Flood Insurance Program (NFIP) from 2020 to 2025, reflecting significant flood risks. Louisiana and Texas also reported significant claims during this timeframe.
The protection gap remains prominent in states like Florida, with a gap nearing $3.67 billion, followed by Pennsylvania and West Virginia. According to Mark Friedlander from the Insurance Information Institute, many homeowners underestimate their flood risk, particularly those residing inland.
Flood risk is anticipated to grow due to climate change, urban expansion, and deteriorating infrastructure. Current flood maps cover only 60% of the continental U.S., and a small proportion has been updated in the last decade, potentially undervaluing risk exposures.
Evaluating Flood Insurance Coverage Options
The average cost of a standard NFIP policy is $1,271 annually. This cost can vary greatly based on geographic location and specific risk factors. In higher-risk states like Louisiana and Florida, premiums reflect the increased risk, while costs in non-coastal areas can be considerably lower.
Flood coverage options include both NFIP and private insurers, with private policies often providing higher coverage limits and extra benefits, such as living expenses. Policies differ in waiting periods, emphasizing the importance of timely procurement before flood season arrives.
With nationwide flood risks rising due to climate changes and infrastructure weaknesses, there is a need for a reassessment of insurance needs and increased awareness among homeowners.
