We're in a coastal area and carry 3 types of insurance 1) regular homeowners 2) flood and 3) wind. The wind policy is what will cover things like your roof blowing away in a tropical storm. You MAY be able to skip flood insurance, but I would quote it before making that decision.
As you do renovations on the house, consider things like changing windows to hurricane glass or getting approved shutters, switching the roof to metal, and installing storm rated exterior doors. This not only lowers your insurance costs, it makes the house more valuable.
