What is flood insurance?

Flood insurance is a type of property insurance that covers your home and personal property for losses caused by water damage due to flooding. The cause of flooding can vary but can include things like

  • Heavy or prolonged rain
  • Melting snow
  • Coastal storm surges
  • Blocked strom drainage systems
  • Levee dam failure

Flood coverage is considered catastrophe insurance, much like earthquake insurance. Flood insurance isn't part of your homeowners policy so if you need coverage, you'll have to get a separate policy.

What types of natural disasters does flood insurance typically cover?

Flood insurance covers physical losses from flooding and claims that resulted from flood-related events caused by certain natural disasters. Here are a few scenarios typically covered by a flood insurance policy

  • Heavy or prolonged rain causing rivers, lakes, and other bodies of water to overflow and lead to flooding
  • Melting snow leading to excess water and ultimately, flooding
  • Coastal flooding and storm surges causing sea levels to rise
  • A blocked storm drainage system causing water to back up
  • A levee or dam break causing sudden flooding
  • Flooding due to a tropical storm
  • Groundwater flooding

Keep in mind flood insurance won't cover damages caused by flood induced landslides, but it may cover mudslides.

How do I know if I'm at risk for flood damage?

There are several ways to determine if you're at risk for flood damage1

  1. Review flood maps. The Federal Emergency Management Agency maintains flood maps and risk assessments that show how likely it is for an area to flood.
  2. Determine if your home is subject to local flooding conditions. If your home is in an area where it's more likely to flood due to heavy rains, poor drainage, etc., you may want to get flood insurance.
  3. Get a flood hazard assessement. This can help you gauge the probability of your home having a catastrophic flood-related event, as well as the potential damage.

Keep in mind floods caused by severe weather-related occurrences can happen anywhere and the damage can be costly. Even if you don't live in a high-risk flood zone, you may want to consider flood insurance.

How do I get flood insurance?

The National Flood Insurance Program is managed by the Federal Emergency Management Agency and provides flood insurance to property owners, renters, and businesses. You Generall have three options for securing flood insurance.

  • Through your current home or property insurance company. Most insurance companies have the ability to write flood insurance through the National Flood Insurance Program, which is admisistered by the Federal Emergency Management Agency.
  • By searching the National Flood Insurance Program directory. If you don't already have a homeowners policy or if your insurance provider can't write flood insurance, you can search for a provider who offers coverage through the National Flood Insurance Program's directory.
  • Through a private flood insurance carrier. Private flood insurance is an alternative to the government-backed National Flood Insurance Program. Coverage is offered independently by certain companies who have their own reinsurance programs and don't have to abide by the requirements set forth by the Federal Emergency Management Agency for policies written through the National Flood Insurance Program.

Private flood insurance companies may offer higher coverage limits than the National Flood Insurance Program, as well as more comprehensive coverage options, such as additional living expenses if you are forced to reside in a hotel or rental home until repairs can be made to your home.

Is flood insurance required by law?

Homeowners genderally aren't required by law to carry flood insurance.

  • However, there may be some situations where a homeowner is mandated to have it if you have a federally backed mortgage, such as a Federal Housing Administration loan, a Veteran's Association loan, or if you're seeking any other type of home loan from a federally regulated or insured lender, you may be required to get coverage for flood insurance as a condition of your loan.
  • If your property has had flood damage in the past and the owner received federal disaster assistance, you may be required to buy flood insurance to be eligible for future aid.
  • If you live in a flood zone, your mortgage lender may require you to secure flood insurance.
