Homeowners in 19 coastal states and Washington, D.C., are most affected by these deductibles due to their exposure to hurricanes and tropical storms. The financial impact can be significant, as percentage-based deductibles often result in higher out-of-pocket costs compared to standard deductibles. Additionally, flood damage is not covered under standard homeowners insurance, requiring separate flood insurance policies. Understanding the differences between named storm and hurricane deductibles is crucial for homeowners to prepare financially and ensure adequate coverage during storm seasons.
