When you buy a home, one of the first things you’re told to do is get homeowners insurance. But once that policy is in place, how much do you actually know about what it covers? If a fire breaks out or someone breaks into your home, you might assume you’re protected—but what about floods, earthquakes, or other disasters?
This guide breaks down exactly what disasters are covered by home insurance and highlights the gaps that may surprise you. Knowing where your policy stands helps ensure you’re not caught off guard when the unexpected happens.
What Standard Homeowners Insurance Typically Covers
Most homeowners purchase an HO-3 policy, which is the standard form of homeowners insurance in the U.S. It covers your home against damage from certain perils, as well as personal property and liability claims.
Here are the most common covered disasters:
✅ Fire and Smoke
One of the most basic and essential protections in any policy. If a fire damages your home or personal belongings, you’re covered. This also includes smoke damage.
✅ Theft and Vandalism
If your home is burglarized or vandalized, most standard policies will pay to repair the damage and replace stolen items, subject to your coverage limits and deductible.
✅ Windstorms and Hail
Damage caused by high winds or hail—such as roof damage from a storm—is usually covered. However, if you live in a hurricane-prone area, you may need separate hurricane or windstorm insurance.
✅ Lightning
Damage caused directly by lightning strikes is covered. This includes fires or damage to electronics due to power surges.
✅ Explosions
Gas leaks or other types of accidental explosions are generally included under standard policies.
✅ Weight of Snow or Ice
In colder climates, heavy snow and ice buildup that causes roof collapse or other damage is typically covered.
✅ Falling Objects
If a tree branch or satellite dish falls on your home, your policy usually covers the resulting damage.
What’s Usually NOT Covered by Standard Home Insurance
This is where things get tricky. Many homeowners assume that “disasters” means everything—but some of the most expensive and common types of damage are often excluded.
❌ Floods
Flooding from heavy rain, hurricanes, or overflowing rivers is not covered under standard homeowners insurance. You’ll need to purchase flood insurance through FEMA’s National Flood Insurance Program (NFIP) or a private insurer.
❌ Earthquakes
Most policies exclude earthquake damage. If you live in a high-risk area like California, you’ll need to buy earthquake insurance separately.
❌ Sewer Backup
If your sewer system backs up and floods your basement, you’re probably not covered unless you’ve added an endorsement for sewer or water backup.
❌ Mold and Pest Damage
Mold that results from long-term leaks or humidity is often excluded. Similarly, damage from termites, rodents, or other pests isn’t covered because it’s considered preventable.
❌ Maintenance Issues and Wear and Tear
Home insurance doesn’t act as a maintenance plan. So if your roof leaks due to old age or your HVAC system breaks down, you’ll have to pay out of pocket unless damage is caused by a covered peril.
How to Close the Gaps in Your Coverage
Knowing what’s not covered is the first step toward full protection. Here are some smart ways to make sure your home is fully insured:
-
Add endorsements for common exclusions like sewer backup, identity theft, or high-value personal items.
-
Buy separate flood or earthquake insurance if you live in a high-risk area.
-
Conduct an annual insurance review to adjust for renovations, new belongings, or lifestyle changes.
-
Increase your personal property limits if you own expensive jewelry, art, or electronics.
Conclusion: Don’t Wait for Disaster to Find Out
Too many homeowners only discover what’s not covered by their policy after disaster strikes—and by then, it’s too late. Understanding what disasters are covered by home insurance helps you make smarter decisions today that protect your future.
Fire, theft, wind, and lightning are usually covered—but floods, earthquakes, and maintenance issues are not. Review your policy carefully, ask your insurer the right questions, and invest in additional protection if needed.
A well-informed policyholder is a well-protected one.
