Standard home insurance in Colorado does not cover flood damage. For that, you will need to add flood insurance to your existing home policy or purchase separate flood coverage from a private insurer or the government-backed National Flood Insurance Program (NFIP).
Colorado's varied terrain makes it one of the more flood-prone states in the country. Flash floods are the biggest culprit, typically triggered by slow-moving thunderstorms that drop intense rainfall faster than the ground can absorb it. The 2013 Front Range floods drove that point home, dropping 6 to 18 inches of rain across large portions of the foothills and causing nearly $4 billion in damage across 15 counties. If you own a house here, flood insurance deserves a serious look.
Does homeowners insurance cover flooding in Colorado?
No, home insurance does not cover flood damage. Whether water enters your home from rising rivers, heavy rainfall, stormwater runoff, or mudflow, your home insurance policy won't pay for the repairs.
That said, home insurance does cover some water damage. The difference comes down to where the water comes from and why. Covered events tend to be sudden and accidental, originating inside the home rather than from outside natural forces — think plumbing leaks, malfunctioning appliances, overflowing drains, or frozen and burst pipes. Precipitation can also be covered if it enters the home as a direct result of storm damage, like rain getting in through a roof torn up by wind. What isn't covered is water that originates outside your home and makes its way in. For that, you’ll need flood insurance.
Who needs flood insurance in Colorado?
In certain situations, you may be required to purchase flood insurance in Colorado. Flood insurance is likely mandatory if:
-
You have a federally backed mortgage, like an FHA, USDA, or VA loan, and you live in a Special Flood Hazard Area (SFHA)
-
Your mortgage lender requires flood insurance, even if you don’t live in an SFHA
-
You received federal disaster aid when your home flooded in the past
Do you need flood insurance if it’s not required?
Even if you don’t live in a high-risk area for floods, carrying flood insurance in Colorado is generally a good idea. Between 2014 and 2024, 29% of NFIP flood claims originated from areas that are not considered high-risk for floods.
Colorado has several factors that can lead to floods, even in low-risk areas:
-
Excessive accumulation of water from rapid or high-volume precipitation or snowmelt
-
Overflowing of lakes and rivers
-
Flash floods caused by thunderstorms moving slowly over a concentrated area
-
Wildfire-scorched land creating a water repellent layer of vegetation and charred soil
How to get flood insurance in Colorado
There are a few ways to secure flood insurance in Colorado: via an endorsement, through a private insurer, or through the National Flood Insurance Program, backed by the Federal Emergency Management Agency (FEMA).
Private flood insurance
Some insurers let you expand your home insurance policy with an endorsement — an optional add-on that can include flood coverage. Otherwise, you can purchase flood insurance as a standalone policy through your existing insurer or another private insurance company.
Private insurance has several key benefits over government-backed policies:
-
Coverage limits: NFIP plans cover up to $250,000 for your home's structure and up to $100,000 for your belongings,which may not be enough if your property is worth more. Private insurance typically offers higher policy limits.
-
Loss of use coverage: Private policies may offer loss of use (sometimes referred to as additional living expenses) coverage, which helps pay for living expenses when a flood causes you to temporarily vacate your home while repairs are being made.
-
Basement coverage: NFIP plans cover only certain basement items — mainly essential equipment like furnaces, water heaters, and sump pumps that are installed and connected to power. Finished walls, flooring, and most personal belongings stored in a basement aren't covered. Private flood policies may fill that coverage gap.
-
Replacement cost value coverage: Private flood policies may offer replacement cost value (RCV) for contents coverage, which pays to replace damaged belongings at today's prices. NFIP contents coverage, by contrast, pays actual cash value (ACV) — meaning it factors in depreciation, so older items are worth less at claim time than what it would actually cost to replace them.
-
Waiting periods: Private policies can offer coverage that takes effect faster (or immediately) than NFIP plans, which have a 30-day waiting period.
Private flood insurance is only available where private insurers choose to offer it. You may not be able to find an affordable private policy in a high-risk area, and the insurer could always choose not to renew your policy upon expiration.
National Flood Insurance Program
You can also buy a federally backed NFIP policy if you live in a participating Colorado community. NFIP policies are administered by FEMA and sold through private insurers or directly through FEMA.
NFIP policies can't be canceled by your insurer, but the program isn't without uncertainty. Because it requires periodic congressional reauthorization, lapses have temporarily shut down new policy sales and renewals — this is not a concern with private flood insurance.

How much does flood insurance cost in Colorado?
The cost of private flood insurance in Colorado will vary depending on the specifics of your home, your exact location, and your coverage details. How much you pay through a private insurer could be less than an NFIP policy, but this is not guaranteed.
The median cost of an NFIP policy in Colorado is $786. The NFIP uses a pricing system called Risk Rating 2.0 to set policy costs (called premiums), which replaced an older model that largely based rates on whether a home was inside or outside a FEMA-designated flood zone. Under Risk Rating 2.0, your premium reflects your home's specific risk factors — things like its distance to water, the cost to rebuild, and the types of flooding it's exposed to. That means two homes on the same street could pay very different rates.
In general, some of the factors affecting the cost of flood insurance include:
-
Coverage limits: The more coverage you want for the structure of your home and its contents, the more your policy will cost.
-
Deductible: A deductible is the amount of damage you are responsible for covering out of pocket in the event of an approved claim. If you choose a higher deductible, you will pay less for coverage. However, make sure it’s an amount you could comfortably afford.
-
Flood risk: The higher your region’s flood risk, the more expensive your policy will be.
-
Elevation level: If your home’s ground level is at or above base flood elevation (BFE), which is the height that flood waters are expected to rise, you might pay less for coverage.
-
Basement: Whether or not you have a basement affects policy rates, as basements are inherently more risky.
-
Age and construction: Newer homes built from modern materials may qualify for lower rates than older homes.
Pro tip: The best way to determine your home’s elevation is to check if your local floodplain manager has an elevation certificate (EC) for your property on file. You can often find your local floodplain manager on city or county government websites. If there isn’t an EC, you can get one by hiring a licensed surveyor. This may help you qualify for lower rates if it shows your home’s elevation is at or above the BFE.
Frequently asked questions
Is flood insurance required in Colorado?
When you have a federally backed mortgage and you live in a Special Flood Hazard Area, you are required to get flood insurance in Colorado. You also must get flood insurance if you previously received federal disaster assistance for flooding in order to maintain eligibility for future aid. Some private mortgage lenders may also require flood insurance for your specific property.
What does Colorado flood insurance cover?
Flood insurance covers losses and damage caused by flooding from overflowing bodies of water, storm surges, rapid snowmelt, flash flooding, and mudflow. You can buy building coverage for the structure of your home and contents coverage for your personal belongings.
Does flood insurance cover snowmelt damage in Colorado?
If snowmelt causes a legitimate flood, flood insurance may cover the losses. But ice dams that form along the edge of your roof and precipitation intruding into your home after a storm may fall under your traditional home insurance coverage (if it gets covered at all).
How long does it take for flood insurance to kick in?
NFIP policies take effect 30 days after you buy the policy — you won’t have coverage until the waiting period expires. Private policies may kick in sooner, sometimes between 10 to 15 days after purchase. Either way, it's best to purchase flood insurance well ahead of spring snowmelt season. Note that periods may be waived altogether if you’re buying a home with a federal mortgage, your community flood map changed, or you’re taking over the policy from a previous homeowner.
Can I add flood coverage to my existing homeowners policy?
Some insurers allow you to add flood insurance to your existing home insurance policy via an endorsement, which can help simplify things when you need to file a claim. Otherwise, you can purchase a standalone flood policy from your existing home insurer (if available), another private insurance company, or the FEMA-backed NFIP.
