Here is the gap that costs Gulf and Atlantic homeowners the most: standard homeowners insurance does not cover flood. Rising water — whether from storm surge, an overflowing river, or days of heavy rain — is excluded. With hurricane season weeks away, this is the coverage to sort out now. This is educational information, not a quote; availability and pricing vary by property and insurer.
Why homeowners policies exclude flood
Flood is a catastrophic, geographically concentrated risk. A single storm can damage thousands of homes at once, which is difficult for ordinary property insurance to absorb. As a result, flood has long been handled separately — historically through a federal program, and increasingly through private insurers as well.
The NFIP option
The National Flood Insurance Program, administered by FEMA, has been the traditional source of flood coverage. A few things to know:
- · **Coverage limits** are capped at set maximums for the building and its contents, which may or may not fully cover a higher-value home.
- · **Waiting period** — there is generally a 30-day waiting period before a new NFIP policy takes effect, which is precisely why you cannot wait until a storm is in the forecast.
- · **Risk Rating 2.0** — FEMA's current methodology prices policies based on a property's specific flood risk rather than broad zone averages, so two nearby homes can be priced differently.
Private flood insurance
A growing private flood market now competes with the NFIP. Private policies can sometimes offer higher coverage limits than the NFIP caps, different terms, and in some cases shorter waiting periods. They are not available everywhere or for every property, and terms vary widely by insurer, so it is worth comparing rather than assuming the NFIP is your only option.
Know your flood zone — but do not stop there
Lenders generally require flood insurance for homes in high-risk flood zones, but a large share of flood claims come from properties outside those zones. Being in a lower-risk zone means coverage is not mandatory and is often cheaper — it does not mean you cannot flood. Mapping your actual risk is more useful than relying on whether the lender requires it.
What to do before June 1
- · Confirm whether you currently carry any flood coverage at all.
- · If you do not and want it, account for the waiting period — buy now, not when a storm is named.
- · Compare the NFIP against any private options available for your property.
The Alliance take
The 30-day waiting period is the detail that turns "I meant to get flood insurance" into an uncovered loss. If you have been putting it off, the start of the season is the deadline that matters.
