The short answer

What Homeowners Insurance Covers

Homeowners insurance typically pays for water damage that starts inside your home. That includes a burst pipe, an overflowing bathtub, or a leaking water heater. It also covers damage from a sudden appliance failure, like a washing machine hose that lets go.

This coverage usually extends to the structure of your home and your personal belongings, minus your deductible. It may also help with temporary housing if your home becomes unlivable. However, the cause must be sudden and accidental, not gradual wear or neglect.

What Flood Insurance Covers

Flood insurance is a separate policy that covers damage from water that comes from outside and rises. That includes heavy rain that seeps into your crawlspace, a nearby river overflowing its banks, or storm-driven water. It is backed by the National Flood Insurance Program, though private options exist.

Flood policies cover the structure and contents, but limits are lower than homeowners insurance. You can buy coverage for the building, the contents, or both. A waiting period usually applies before the policy takes effect, so planning ahead matters.

  • Covers rising water from storms, rivers, or runoff
  • Separate policy with its own premium and deductible
  • Pays for structural damage and often personal items
  • May require a 30-day waiting period before coverage starts
  • Does not pay for damage from internal leaks or pipe bursts

Key Differences at a Glance

The main difference is the source of the water. Homeowners insurance handles water that comes from inside your plumbing or appliances. Flood insurance handles water that comes from outside and covers the ground, like rain that soaks into your crawlspace or a stream that overflows.

Another difference is cost. Flood insurance premiums are set by federal or private rates and can vary widely based on your property's flood risk. Homeowners insurance is bundled with your home policy and its cost depends on your home's value, location, and coverage limits.

  • Homeowners: covers burst pipes, appliance leaks, roof leaks
  • Flood: covers rising water, overflowing rivers, storm-driven water
  • Flood is always separate from homeowners
  • Homeowners does not cover flooding in most cases
  • Flood coverage has lower limits and a waiting period
  • Both require a deductible before payout

Why You Might Need Flood Insurance

Even if your home is not in a high-risk flood zone, flooding can still happen. Heavy rain can overwhelm drainage systems, and water can pool around foundations. A 1% annual flood risk may sound small, but over a 30-year mortgage, that adds up to a significant chance.

Check your property's flood risk on FEMA's map, regardless of your climate. Your mortgage lender may require flood insurance if you are in a special flood hazard area. Even if not required, it is worth considering for peace of mind, especially if your home has a lower level or crawlspace.

How to Handle Water Damage Claims

If water damage occurs, document everything. Take photos of the damage, the source, and any affected belongings. Contact your insurance company right away to start a claim. Keep receipts for any emergency repairs you make to prevent further damage.

For flood damage, your flood insurer will handle the claim separately from your homeowners policy. For internal leaks, your homeowners policy applies. In either case, the claims process involves an adjuster who assesses the damage. Policies vary, and your insurer decides what is covered.

Frequently asked questions

Do I need flood insurance if I don't live in a flood zone?

Flooding can happen anywhere, not just in mapped high-risk areas. Heavy rain, clogged drains, or nearby construction can cause water to rise. Even a small flood can cost thousands in repairs. Check your risk and consider a policy if you want that protection.

Can I buy flood insurance from my homeowners insurer?

Many insurers sell flood policies through the National Flood Insurance Program or private markets. You can often add it to your existing policy, but it is a separate contract with its own terms. Ask your insurance agent about options and pricing.

What should I do right after flood damage?

Act quickly to dry the area and prevent mold growth. Remove wet items if safe, and turn off electricity if water is near outlets. Document damage with photos and contact your flood insurer. For major cleanup, local water damage pros can help with drying and restoration.
