What Does Flood Insurance Cover in New Hampshire?

If an overflow event damages your house, flood insurance can provide benefits up to your coverage limit for repairs or rebuilding. When you purchase a New Hampshire flood insurance policy, you can choose to purchase structural coverage, contents coverage, or both.

If you are a renter, you will only want to purchase contents coverage. Similarly, landlords may only be interested in structural coverage. Most homeowners, however, will want to purchase both.

What's Not Covered by New Hampshire Flood Insurance?

New Hampshire flood insurance does not cover damage from mudslides, even if it was caused by heavy rains and flooding. However, if your home has damage from erosion directly related to uncommon water movement, it is likely covered. Overall, flood insurance comes with several important exclusions that are important to be aware of. In New Hampshire, don't expect flood insurance to cover any of the following:

  • Outdoor property like septic systems, decks, patios, landscaping, wells, hot tubs, pools, and fences
  • Business property and interruptions
  • Personal belongings stored in basements
  • Vehicles
  • Additional living expenses

Additionally, flooding caused by sewer backups and line breaks typically isn't covered by flood insurance. However, you can add sewer backup endorsements to your New Hampshire homeowners insurance if you want this coverage.
