One of the most important things a homeowner can learn is that flood damage is excluded from a standard homeowners policy. Rising water — from storms, overflowing rivers, storm surge, or heavy rainfall — is not covered. Flood insurance has to be purchased as a separate policy.

Two ways to buy it

  • NFIP (National Flood Insurance Program) — the federal program, sold through participating insurers. Coverage amounts and rules are standardized, with maximum limits set by the program.
  • Private flood insurance — offered by private carriers. It can sometimes provide higher limits, additional coverages, or more competitive pricing, particularly for higher-value homes that exceed NFIP caps.

The 30-day waiting period

Flood coverage typically does not take effect immediately. A standard 30-day waiting period applies before a new policy is active. That's why a homeowner can't wait until a storm is in the forecast to buy it — by then it's too late. Some exceptions exist, such as a policy tied to a new loan closing.

Key points for clients

  • Flood risk isn't limited to coastal or high-risk zones — many flood claims come from outside mapped flood areas.
  • If a property is in a high-risk zone with a federally backed mortgage, flood coverage is usually required by the lender.
  • Buy early because of the waiting period.

Educational only — confirm against the actual policy and your carrier's guidelines.
