Tornado claims are processed under a standard homeowners policy with the cause of loss classified as windstorm. In most states, the standard flat-dollar deductible applies ($500 to $2,000). In tornado-prone and coastal states (Texas, Oklahoma, Kansas, Alabama and parts of the Midwest) insurers apply a separate percentage-based wind/hail deductible ranging from 1% to 5% of the dwelling coverage limit.
The wind/hail deductible structure is where most tornado claims surprise policyholders. On a $250,000 dwelling policy, a 2% wind/hail deductible equals $5,000 out of pocket before coverage applies. This deductible is separate from the standard deductible and applies only to wind-related claims, including tornadoes.
