Rising insurance costs are increasingly eroding home values in storm-prone areas, as a growing share of the U.S. housing market faces expanding hurricane risk well beyond traditional coastal boundaries.
According to Cotality's 2026 Hurricane Risk Report, more than 32.2 million U.S. homes now face moderate or greater hurricane wind risk, representing more than $12.26 trillion in reconstruction cost value. As that exposure spreads inland and into higher-value markets, insurance premiums are rising—and beginning to weigh directly on property pricing.
"For every 10% increase in insurance premiums, the house's value decreases by 4.6%," said John Rogers, chief data and analytics officer for Cotality, speaking June 1 at the National Association of Real Estate Editors Conference in Miami.
The dynamic is becoming a defining issue for homeowners and buyers alike, particularly in markets where risk is less visible but financially significant. Many properties facing elevated exposure are either underinsured or located outside traditional risk zones, leaving owners vulnerable to both rising costs and declining valuations.
New York illustrates how this shift is playing out in real time. More than 3.27 million homes in the state carry moderate or higher wind risk, totaling $1.93 trillion in potential reconstruction costs—the highest concentration in the nation. According to the report, the combination of dense development, aging housing stock and high property values is amplifying both insurance pressures and the potential for price impacts.
Other major metros are seeing similar dynamics. Houston ranks second with 2.17 million exposed homes and $824 billion in reconstruction cost value, followed by Miami with 2.04 million homes at risk. New York also leads the nation in storm surge exposure, with more than 631,000 vulnerable homes, surpassing Miami, Tampa and New Orleans.
Even in regions where hurricanes are less frequent, the financial consequences are becoming harder to ignore, according to Cotality.
Intensifying Storm Risk Adds Pressure
The 2026 hurricane season is expected to bring fewer storms overall due to El Niño conditions, but those that do form are likely to be more intense—raising the potential for higher losses and, in turn, further pressure on insurance pricing.
Rogers said severe convective storms already account for 48% of all catastrophic insurance claims. There have been 563 tornadoes so far this year, typically accompanied by hail, high winds and flooding—events that can drive claims activity well beyond coastal مناطق.
Mitigation is one of the few levers available to homeowners. Some states offer grants to strengthen roofs, and Rogers said that those who complete upgrades can cut wind insurance premiums by up to 55%. Florida, he noted, stands out for both the strength of its building codes and the consistency with which they are enforced.
Hidden Risks, Uneven Coverage
While Florida and Texas remain the largest concentrations of hurricane exposure, with 8.25 million and 4.8 million at-risk homes respectively, the report emphasizes that risk is spreading geographically—and not always in ways reflected in insurance requirements.
One of the clearest examples is hidden flood exposure. More than 927,000 homes, representing $405 billion in property value, face high hurricane-related flood risk despite sitting outside federally mandated flood insurance zones. These properties generate an estimated $1.73 billion in annual flood losses, leaving many homeowners exposed to out-of-pocket costs that can further erode property value.
Louisiana ranks among the states most affected by this gap. Orleans Parish alone accounts for $41.8 billion in at-risk property value outside mandatory flood zones. Jefferson Parish, along with Brevard County in Florida, Harris County in Texas and Suffolk County in New York, also ranks among the most exposed, according to the report.
Climate Pressures Extend Beyond Wind and Water
The report also points to rising heat as an additional stressor that could compound insurance and valuation challenges over time. The Midwest is seeing the fastest increase in heat waves, while Texas and Florida continue to lead in frequency. Counties including Bexar, Dallas, Harris and Tarrant in Texas, along with Miami-Dade in Florida, are among the most affected.
As climate-related risks broaden and intensify, the link between insurance costs and home values is likely to become more pronounced—reshaping how both markets price risk in the years ahead.
