Types of Water Damage Not Covered in Home Insurance

Water damage is one of the most common and expensive issues homeowners face in Canada. From burst pipes and roof leaks to flooded basements, the repair costs can be overwhelming. Although standard home insurance often covers some types of water damage, it usually excludes others—leaving homeowners exposed unless they secure additional protection.

What Standard Home Insurance Covers?

Most standard policies cover sudden and accidental water damage. These typically include:

  • Burst pipes or appliance failure, such as a sudden leak from a washing machine or dishwasher—so long as the event is unexpected and not the result of neglect.
  • Roof leaks caused by a covered peril, such as storm damage or falling debris. Damage resulting from normal wear and tear or poor maintenance is usually excluded.
  • Damage from extinguishing a fire, such as water flooding your home during firefighting efforts.

It is important to note that insurance usually covers the resulting damage, not necessarily the source. For example, while your policy may cover the cost of repairing water-damaged flooring or drywall, it may not pay to replace corroded pipes that caused the leak.

Common Water Damage Scenarios Not Covered

  1. Flooding and Overland Water

    Flood damage, whether from heavy rainfall, overflowing rivers, melting snow, or rising groundwater, is not covered under standard policies. Homeowners who live in flood-prone areas must purchase separate flood or overland water insurance to be fully protected.

  2. Sewer Backup and Drainage Failures

    Damage from sewer backups, sump pump failures, or clogged drains is another common exclusion. Optional sewer backup coverage is widely available and provides important protection, particularly for homes with basements.

  3. Gradual Leaks and Maintenance Issues

    Slow leaks or gradual water damage are rarely covered. This includes damage from faulty plumbing, aging roofs, or neglected appliances. Insurers generally expect homeowners to maintain their properties, so damage caused by ongoing issues is often considered preventable.

  4. Groundwater Seepage

    Water entering a home through the foundation or basement walls due to high water tables or heavy rainfall is also excluded. Specialized coverage or endorsements may be required to protect against this type of damage.

  5. Ice Dams

    Some home insurance policies cover sudden interior damage, but many exclude claims linked to poor upkeep or insulation. Optional endorsements are sometimes available for added protection against ice damming.

How to Protect Your Home from Water Damage?

While exclusions are common, homeowners can take steps to secure broader protection and reduce risks.

  1. Work with a Property Insurance Broker

    Brokers understand which risks are common in your area and can recommend endorsements to fill gaps in your policy.

  2. Add Endorsements Where Needed

    Popular add-ons include:

    • Overland Water (Flood) Coverage
    • Sewer Backup Coverage
    • Ice Damming and Roof Drainage Coverage
  3. Maintain Your Home

    Inspect your roof, plumbing, and foundation regularly. Replace aging pipes, repair shingles, and service appliances to reduce the likelihood of leaks or backups.

  4. Install Preventive Measures

    Tools such as sump pumps, backwater valves, and basement waterproofing significantly reduce the risk of water damage in flood-prone areas.

  5. Document Preventive Work

    Keep records of repairs, upgrades, or professional services. This demonstrates responsible ownership and can support insurance claims.

  6. Report Damage Quickly

    If water damage occurs, notify your insurer immediately. Delays can worsen the damage and increase the risk of a denied claim.

Water damage is a serious concern for Canadian homeowners, and while many types of water damage are covered by standard property insurance policies, some of the most costly incidents, such as flooding, sewer backups, and gradual leaks, are often excluded.
