Flooding can cause a significant amount of damage to the structure and/or personal property inside your home. If a flood occurs then your flood insurance policy will pay for the damage to your property. Most Homeowners policies do not cover flood damage so you will need a separate policy for the proper coverage. Most flood insurance is written through the National Flood Insurance Program. It normally takes 30 days from the date of purchase for flood insurance to go into effect so you should not delay in purchasing this coverage.
