Named Storm Deductible
A percentage-based deductible triggered only when damage is caused by a storm officially named by the National Weather Service.
What It Is
A Named Storm Deductible is a specific type of windstorm deductible that applies only when property damage is caused by a storm that has been officially named by the National Weather Service—tropical storms and hurricanes. Unlike a general windstorm deductible that applies to any wind event, a named storm deductible is triggered only when the damaging wind is associated with a named tropical weather system.
Named storm deductibles are typically expressed as a percentage of the property's insured value, commonly ranging from 2% to 5%. The distinction between named storm and windstorm deductibles matters because severe thunderstorms, tornadoes, and other non-named wind events would be subject to the standard all-perils deductible under a named storm deductible structure, but would trigger the higher deductible under a general windstorm deductible.
The exact triggering criteria vary by policy. Some policies trigger the named storm deductible when any named storm damage occurs. Others require the National Weather Service to issue a hurricane watch or warning for the insured's specific county before the named storm deductible applies.
Why It Matters for Brokers
The difference between a named storm deductible and a general windstorm deductible can save commercial property owners significant money on non-hurricane wind claims. Brokers should negotiate for named storm deductibles rather than general windstorm deductibles whenever possible, as this limits the elevated deductible to only the most catastrophic events while keeping the standard deductible for routine wind damage.
Real-World Example
A commercial building in Charleston, SC valued at $4.5M has two deductible options: a 3% windstorm deductible ($135,000) or a 3% named storm deductible ($135,000). A severe thunderstorm with 70 mph straight-line winds causes $210,000 in roof damage. Under the windstorm deductible, the elevated 3% deductible applies: insurer pays $75,000. Under the named storm deductible, the standard $10,000 all-perils deductible applies because the storm was not named: insurer pays $200,000. Same wind, same damage—$125,000 difference based on the deductible type.
Common Mistakes
- 1Confusing named storm deductibles with general windstorm deductibles—named storm is narrower and more favorable to the insured for non-hurricane wind events.
- 2Not verifying the specific triggering criteria for the named storm deductible, which can vary between 'any named storm damage' and 'hurricane watch/warning issued for the county.'
- 3Failing to negotiate for a named storm deductible when the carrier initially offers a general windstorm deductible—many carriers will accommodate the request.
