Hurricane insurance is a little tricky. Private homeowners insurance does not cover flood damage, but it should cover any damage caused by hurricane winds. Even so, many homeowner policies have special deductibles for hurricane damage that are separate from the general deductible for other damages. While the general deductible is likely set at a dollar amount, the deductible for hurricane damage is often set as a percent of the hurricane costs. It's usually around 3 percent, says Ernst Csiszar, a professor of finance at the University of South Carolina in Columbia, although it can run as high as 5 percent of the damage costs.
Any hurricane damage from water, not wind and rain, is covered by flood insurance, which must be purchased separately through the federally run National Flood Insurance Program.
