Frequently Asked Questions
Flood insurance is required by mortgage lenders if your home is in a FEMA-designated flood zone (Zones A, AE, AH, AO, V). Even if not required, it's highly recommended for all homeowners.
Flood insurance covers damage to your home's structure (dwelling coverage) and personal belongings (contents coverage) from rising water. It does not cover mold, mildew, or damage from sewer backups unless caused by flooding.
You can find your flood zone by visiting the FEMA Flood Map Service Center and entering your address. Your insurance agent can also help determine your flood zone.
No, standard homeowners insurance does not cover flood damage. You need a separate flood insurance policy, typically through the NFIP or a private insurer.
