Homeowners insurance can cover many forms of sudden damage, but it does not cover every natural disaster. For residents of Lewisburg, TN, the most significant exclusions to understand are usually flooding, earthquakes, earth movement, and certain water-related losses.
The exact answer depends on the policy wording, endorsements, deductibles, and cause of damage. A standard homeowners policy may cover wind, hail, lightning, fire, falling trees, and many tornado-related losses while excluding other disasters entirely. ([tn.gov](https://www.tn.gov/commerce/insurance/consumer-edu/homeowners/focus.html?utm_source=openai))
Which natural disasters are commonly excluded?
The two most common exclusions are flooding and earthquake damage. Other earth movement events, such as landslides or mudslides, may also be excluded or limited.
Common exclusions or coverage gaps include:
- Flooding from overflowing streams, heavy runoff, standing water, or surface water
- Earthquake damage and other forms of earth movement
- Landslides, mudslides, and sinking or shifting soil
- Sinkhole damage, depending on the policy and location
- Sewer or drain backup unless an endorsement was added
- Certain water damage caused by poor maintenance or repeated seepage
Insurance policies do not use the word “disaster” as the only test for coverage. Instead, they examine the specific cause of loss. For example, a tornado may damage a roof through wind, while the resulting rain enters through the opening. That may be treated differently from rain entering a home without storm-created damage to the roof or walls.
Is flood damage covered by homeowners insurance?
Usually, no. Standard homeowners insurance generally excludes flood damage, even when the flooding follows a severe storm, overflowing creek, drainage problem, or heavy rainfall. Tennessee’s insurance regulators specifically state that flood damage is not included in a typical homeowners policy. ([tn.gov](https://www.tn.gov/commerce/insurance/consumer-edu/homeowners/focus.html?utm_source=openai))
Flooding generally means water that comes from outside the home and affects normally dry land. Examples may include:
- Water rising from a creek or drainage channel
- Runoff moving across a yard and into the house
- Heavy rainfall overwhelming local drainage
- Water entering through foundation walls after surface flooding
- Overflow from nearby waterways
A roof leak caused by wind damage is not usually the same as flood damage. If wind tears away roofing material and rain enters through that opening, the wind-related damage may be covered, subject to the policy terms and deductible. However, water rising from the ground is generally handled under flood insurance rather than homeowners insurance.
Flood insurance is available through the National Flood Insurance Program and other participating sources. Coverage can be relevant even outside areas commonly considered high-risk because localized flooding can occur after intense rainfall or drainage failures.

Does homeowners insurance cover earthquakes in Tennessee?
A standard homeowners policy usually does not cover earthquake damage. Earthquake insurance must generally be added by endorsement or purchased as a separate policy. Tennessee’s Department of Commerce and Insurance notes that earthquake coverage is available in the state and that a standard homeowners policy does not provide this protection automatically. ([tn.gov](https://www.tn.gov/content/tn/commerce/insurance/consumer-edu/weather-disasters/earthquake-safety.html?utm_source=openai))
Earthquake coverage may address damage to the home, detached structures, personal property, debris removal, and additional living expenses, but the details vary. Earthquake policies often have deductibles that are calculated as a percentage of the insured amount rather than as a small fixed dollar amount.
For example, a 10% earthquake deductible on $250,000 of dwelling coverage would be $25,000. Some policies may apply separate deductibles to the dwelling, personal property, or other structures.
Earthquake policies may also contain special limitations involving brick or stone veneer, pre-existing damage, vehicles, external water damage, and land loss. Those details matter for homes with masonry exteriors, detached garages, older foundations, or prior structural concerns. ([tn.gov](https://www.tn.gov/content/dam/tn/commerce/documents/insurance/posts/Consumer_Guide_Earthquake_Insurance.pdf?utm_source=openai))
Are tornadoes, windstorms, and hail excluded?
Tornado damage is typically covered under standard homeowners insurance when the policy includes wind coverage. Wind, wind-driven rain following covered roof damage, hail, lightning, falling trees, and other falling objects are commonly covered causes of loss. ([tn.gov](https://www.tn.gov/commerce/news/2023/12/13/tdci-shares-tips-on-how-to-file-insurance-claims-hire-contractors-and-ensure-home-safety-as-part-of-tornado-recovery-.html?utm_source=openai))
That does not mean every loss after a tornado will be paid. Coverage can be affected by:
- The policy’s wind or hail deductible
- Roof age and condition
- Whether the damage resulted from wind or lack of maintenance
- Whether the structure was properly insured
- Exclusions for detached property, landscaping, or certain outdoor items
- Whether the damage was caused by flooding rather than wind
A common example is a tree falling onto a covered home. Damage to the roof may be covered, but removal of a tree that falls in the yard without damaging an insured structure may have limited or no coverage. Tennessee regulators also identify food spoilage after a power outage and some fallen-tree removal as losses that may not be covered under a standard policy. ([tn.gov](https://www.tn.gov/commerce/news/2023/12/13/tdci-shares-tips-on-how-to-file-insurance-claims-hire-contractors-and-ensure-home-safety-as-part-of-tornado-recovery-.html?utm_source=openai))
What about landslides, mudslides, and sinkholes?
Earth movement exclusions can be broad. Policies may exclude landslides, mudslides, settling, shrinking, bulging, or shifting of earth. The definitions are technical, so the same event may be treated differently depending on whether the movement involves soil, water-saturated earth, rock, or a structure’s foundation.
Sinkhole coverage is also not automatically included in every homeowners policy. Some policies offer limited coverage or optional endorsements, while others exclude sinkhole-related damage. A home with foundation cracks, uneven floors, retaining walls, or drainage concerns may require especially careful review of the earth movement wording.
Damage caused by a covered event may still be insured even when earth movement is excluded. For instance, a fire that follows an excluded event may be treated under the policy’s fire coverage, although the facts and policy language control the claim.
Is sewer backup the same as flooding?
No. Sewer backup and flooding are separate coverage issues.
Flooding usually involves water rising from outside the home. Sewer backup involves water or sewage coming through a drain, sewer line, sump pump, or similar system. Standard homeowners policies commonly exclude sewer or drain backup unless specific coverage has been added. ([tn.gov](https://www.tn.gov/commerce/news/2023/12/13/tdci-shares-tips-on-how-to-file-insurance-claims-hire-contractors-and-ensure-home-safety-as-part-of-tornado-recovery-.html?utm_source=openai))
This distinction matters in areas where intense storms can overwhelm drainage systems. A policy may cover rain damage to a roof but exclude water that backs up through a floor drain. A sewer-backup endorsement may provide coverage, but it may have its own limit, deductible, and exclusions.
How can residents check for disaster exclusions?
The declarations page shows the main limits and deductibles, but exclusions are usually found in the policy form and endorsements. Look for sections labeled:
- Exclusions
- Causes of loss
- Water damage
- Earth movement
- Flood
- Additional coverage or endorsements
- Special deductibles
Ask specifically whether the policy covers flood, sewer backup, earthquake, sinkhole, wind, hail, additional living expenses, detached structures, and personal property. A home inventory with photographs, receipts, and serial numbers can also make it easier to document belongings after a covered disaster. ([content.naic.org](https://content.naic.org/consumer/homeowners-insurance.htm?utm_source=openai))
Residents should also distinguish between an excluded peril and an uncovered maintenance problem. Insurance is generally designed for sudden and accidental losses, not gradual deterioration, preventable leaks, foundation settlement over time, or an aging roof that fails without a covered cause.
Because policies differ, the most reliable answer is found in the actual contract governing the property. A disaster declaration or emergency assistance program does not automatically change a homeowners policy or guarantee payment for excluded damage.
