Extreme weather events are noticeably on the rise. However, many homeowners and renters are unaware that damage caused by natural disasters is not automatically covered by either homeowners insurance or contents insurance.
In this post, you'll learn:
- What is natural disaster damage?
- Does home insurance cover flood damage?

- What are the rules regarding backflow?
- When does it make sense to have natural disaster insurance?
Natural Disaster Protection—The Key Benefits at a Glance

- Protection Against Flooding and Heavy Rainfall
- Protection Against Backflow from the Sewer
- Financial Security in the Event of Natural Disasters
- Can be added to building and household property coverage
- Protection against losses that threaten one's livelihood
What is natural disaster damage?
Natural disasters are events caused by natural phenomena. These include, in particular:
- Flooding Caused by Heavy Rain
- Flooding
- Backflow from the sewer
- Landslide or Land Subsidence
- Earthquake
- Snow load
- Avalanches
Important: Storms and hail are not considered natural disasters. These risks are generally already covered under a standard home or personal property insurance policy.
Does home insurance cover flood damage?
Short answer: No—only with additional protection against natural disasters.
Standard home insurance typically covers the following risks:
- Fire
- Tap water
- Storm
- Hail
Damage caused by heavy rain, flooding, or backflow is covered only if natural disaster coverage has been added as a supplementary coverage option.
The following, among other things, are covered:
• Damage to masonry
• Damaged subfloor
• Destroyed heating systems
• Built-in kitchens
• Cleanup and demolition costs
• Loss of rent due to the property being uninhabitable
Does home contents insurance cover damage caused by heavy rain?
The same applies here: Only when the basic module is included.
Home contents insurance covers all movable property in the home, such as:
- Furniture
- Electrical appliances
- Clothing
- Rugs
- Household goods in the basement
- personal belongings
If the basement floods after heavy rain and furniture or the washing machine is damaged, home contents insurance will only cover the loss if it includes natural disaster coverage.
When does the insurance company pay out in the event of a backup?
A particularly common problem is backflow from the sewer.
In such cases, water from the sewer system flows back into the building—often through floor drains or toilets.
In order for the insurance company to pay, the following requirements must generally be met:
- Natural disaster insurance has been arranged
- A functioning backflow preventer is in place
- The agreed-upon deductible is taken into account
Without a basic coverage component, there is no insurance coverage.
Conclusion: Is natural disaster insurance a good idea?
For many homeowners and renters, the answer today is clearly “yes.”
Because without a basic component, there is no protection in the following cases:
- Flooding
- Heavy Rain
- Backlog
- Flooding
