Natural disasters are where coverage gaps bite hardest, because standard home insurance excludes some of the biggest ones, notably floods and earthquakes, which need separate policies. Knowing what is and is not covered before storm season is one of the most valuable things you can do as a homeowner.

Key takeaways

  • Standard home insurance covers many disasters, including fire, wind, hail, and lightning.
  • Flood and earthquake damage are usually excluded and need separate coverage.
  • Some regions use percentage deductibles for wind, hurricane, or named storms.
  • A percentage deductible can be a much larger out-of-pocket cost than a flat amount.
  • Reviewing your policy and documenting belongings before disaster season pays off.

What standard home insurance covers

A typical homeowners policy covers many disaster-related causes of loss, such as:

  • Fire and smoke
  • Windstorms and hail
  • Lightning

These cover a wide range of damaging events. The catch is that two of the most destructive perils, flood and earthquake, are usually left out.

Floods and earthquakes are separate

Flood damage is excluded from standard policies and is instead covered through the National Flood Insurance Program or some private insurers. Earthquake coverage is also separate and often carries a percentage deductible. If you face either risk, these are the gaps most worth closing.

Peril Standard home policy Where coverage usually comes from
Fire, wind, hail, lightning Typically covered Your base policy
Flood Excluded NFIP or private flood insurer
Earthquake Excluded Separate policy or endorsement

Deductibles can work differently

In many higher-risk regions, wind, hurricane, or named-storm deductibles are calculated as a percentage of your dwelling limit rather than a flat dollar amount. On a higher-value home, that percentage can translate into a sizable out-of-pocket figure, so it is worth knowing in advance which deductible structure applies to you.

How to prepare before disaster season

A little preparation goes a long way:

  1. Review your policy before disaster season, not during a warning.
  2. Add flood or earthquake coverage if you face that risk.
  3. Document your belongings with a home inventory of photos and descriptions.
  4. Confirm whether your area uses percentage deductibles and what they would cost.

Frequently asked questions

Does homeowners insurance cover hurricane damage?

It depends on the cause. Wind damage from a hurricane is often covered, but flooding from storm surge usually is not and needs separate flood coverage. Hurricane-prone areas may also apply a percentage deductible.

Why isn't flood included in my home policy?

Flood is treated as a distinct, high-risk peril and is excluded from standard policies. Coverage is available separately through the National Flood Insurance Program or some private insurers.

What is a percentage deductible?

It is a deductible calculated as a percentage of your dwelling limit rather than a fixed dollar amount. Because it scales with your home's value, it can be larger than a typical flat deductible.
