Understanding Commercial Property Insurance for Water Damage

Water damage can be one of the most costly and disruptive business issues, affecting operations, inventory, and property structures. Whether caused by burst pipes, heavy storms, or internal leaks, understanding how commercial property insurance covers water damage is essential for financial protection.

Water damage remains a significant concern for businesses, with recent data underscoring its prevalence and financial impact. In 2022, water damage and freezing accounted for nearly 28% of homeowners insurance losses, with the average insurance payout for such claims being $13,954. This highlights the potential cost of water-related damage for businesses as well.

In this guide, we’ll break down what’s covered, what’s excluded, preventive measures, and how to file a claim, helping businesses make informed decisions to minimize risks and maximize coverage.

What to Do When You Face Commercial Water Damage

Water damage in a commercial property can disrupt operations, lead to costly repairs, and even result in legal liability if not handled properly. Whether caused by burst pipes, flooding, or roof leaks, acting quickly can help minimize damage and financial loss.

1. Ensure Safety First

• Shut off the main water supply if the damage is due to a plumbing issue.
• Turn off electricity in affected areas to prevent electrical hazards.
• Evacuate employees or customers if the water damage poses health or structural risks.

2. Identify the Source of Water Damage

• Check for burst pipes, leaking roofs, or appliance malfunctions.
• If flooding is from an external source (e.g., storms or sewer backups), determine if your insurance policy covers the damage.

3. Document the Damage for Insurance Claims

• Take clear photos and videos of the affected areas, including damaged equipment, inventory, and property.
• Keep records of any temporary repairs made to prevent further damage.
• Contact your insurance provider immediately to begin the claims process.

4. Start Water Removal and Drying

• Use pumps, wet vacuums, or professional water extraction services to remove standing water.
• Set up fans, dehumidifiers, and ventilation to dry out the space and prevent mold growth.
• Remove and dispose of water-damaged materials that cannot be salvaged.

5. Assess Structural and Electrical Damage

• Hire a licensed contractor to inspect walls, flooring, and structural components for water damage.
• Have an electrician check wiring and outlets before restoring power to ensure safety.

6. Prevent Mold and Secondary Damage

• Mold can grow within 24-48 hours, so address moisture issues immediately.
• Apply mold prevention treatments to at-risk areas.
• Monitor humidity levels and ensure the area remains dry before resuming operations.

7. Contact a Professional Restoration Service

• If the damage is extensive, hiring a commercial water damage restoration company ensures thorough cleanup and repairs.
• Professional services can help prevent long-term structural issues and ensure compliance with safety regulations.

8. Review Your Insurance Policy

• Check if your commercial property insurance covers water damage.
• If caused by floods, ensure you have a separate flood insurance policy, as standard policies often exclude natural flooding.
• Work with your insurer to understand coverage limits, deductibles, and claim requirements.

9. Implement Preventive Measures

• Regularly inspect plumbing, roofing, and HVAC systems to identify leaks early.
• Install water sensors and automatic shutoff valves to detect and control leaks.
• Develop an emergency response plan so employees know how to act quickly in case of future water damage incidents.

Now that you’ve taken the right steps to protect your business from water damage, what happens when the situation is more severe and beyond your control? That’s where commercial property insurance comes in—it can help cover water damage costs and get your business back on track without a major financial setback.

Types of Water Damage Covered Under Commercial Property Insurance

Water damage can severely impact a business, but standard commercial property insurance does not cover all types. Most policies protect against sudden and accidental damage, excluding gradual deterioration or preventable issues.

Knowing what your policy covers helps prevent unexpected financial setbacks.

1. Burst or Leaking Pipes

How It Works

Pipes can burst due to extreme temperatures, high pressure, or unexpected failures, causing water to flood the property. Insurance typically covers repairs and property restoration if the cause is sudden and unavoidable.

Benefits

• Covers the cost of pipe repairs and property restoration
• Prevents major business disruptions caused by unexpected flooding
• Protects inventory, equipment, and structural elements from water damage

Example: A retail store experiences a burst pipe in winter, leading to water soaking the floors, damaging merchandise, and requiring immediate cleanup. Since the incident was unexpected, the insurance policy covers the repairs, damaged inventory, and water extraction costs.

2. Storm-Related Water Damage

How It Works

Strong winds, heavy rain, or hail can damage a building’s roof or windows, allowing water to enter. Water damage may be covered if the storm is a covered peril in the policy.

Benefits

• Helps cover the cost of roof and window repairs
• Pays for water removal and structural drying
• Prevents costly downtime due to storm-related damage

Example

A storm damages a restaurant’s roof, causing rainwater to seep into the ceiling and walls. The insurance policy covers the cost of roof repairs, drying services, and fixing interior damage to prevent mould growth.

3. Fire Sprinkler System Malfunctions

How It Works

Fire sprinklers can activate due to system malfunctions, accidental discharge, or false alarms, leading to water damage inside the property. Insurance will likely cover cleanup and repairs if the activation is sudden and accidental.

Benefits

• Covers water damage from accidental sprinkler activation
• Helps pay for damaged furniture, equipment, and flooring
• Protects against significant repair costs caused by malfunctioning systems

Example: A hotel’s fire sprinkler system malfunctions, releasing water into guest rooms and common areas. The insurance policy helps pay for carpet replacement, furniture restoration, and cleanup services.

4. HVAC and Appliance Leaks

How It Works

Commercial HVAC systems, dishwashers, water heaters, and refrigerators may develop leaks due to unexpected failures. The resulting water damage may be covered if the sudden leak is not due to neglect.

Benefits

• Covers property damage caused by sudden leaks
• Pays for equipment repairs or replacements
• Helps prevent business disruptions caused by unexpected failures

Example: A coffee shop’s water heater suddenly leaks, soaking the floor and damaging nearby electrical outlets. The insurance policy helps cover repairs, water extraction, and equipment replacement.

5. Sewer or Drain Backup (if Endorsed)

How It Works

A backup occurs when wastewater from sewers, drains, or sump pumps overflows into the business property. Standard policies do not cover this unless a sewer backup endorsement is added.

Benefits

• Covers cleanup and sanitation costs after a backup
• Helps pay for damaged flooring, walls, and inventory
• Reduces financial strain from unexpected plumbing failures

Example: A retail store experiences a sewer backup, causing wastewater to flood the restroom and storage areas. With a sewer backup endorsement, the insurance policy covers cleanup, sanitization, and repairs.

Commercial property insurance protects against sudden and accidental water damage, but exclusions exist. Understanding your policy’s coverage and adding necessary endorsements can help safeguard your business from unexpected repair costs, downtime, and financial losses.

Exclusions and Limitations in Water Damage Coverage

While commercial property insurance helps cover sudden and accidental water damage, it does not protect against every type of water-related incident. Many claims are denied due to policy exclusions and limitations, leaving business owners responsible for repair costs. The most common exclusions involve flood damage, gradual leaks, and wear and tear-related issues.

Understanding these limitations can help you assess risks and determine if additional coverage is necessary.

1. Flood Damage Requires Separate Flood Insurance

How It Works

Standard commercial property insurance does not cover flood-related damage. Businesses in flood-prone areas must purchase a separate flood insurance policy through the National Flood Insurance Program (NFIP) or a private insurer.

Why It’s Important

• Protects against storm surges, overflowing rivers, and flash floods
• Covers damage to the building, equipment, and inventory
• Helps businesses recover from severe water-related disasters

Example: A warehouse near a river floods after heavy rainfall, causing significant water damage to stored goods and machinery. Since standard insurance does not cover floods, the business can only receive compensation with a separate flood insurance policy.

2. Exclusions for Gradual Damage and Negligence

How It Works

Insurance companies do not cover slow-developing leaks or damage caused by poor maintenance. If a pipe drips for months, leading to mold growth and structural damage, the claim will likely be denied because it resulted from neglect rather than a sudden event.

Why It’s Important

• Encourages regular property maintenance to prevent claim denials
• Helps businesses avoid unexpected out-of-pocket repair costs
• Ensures that sudden, unavoidable incidents remain covered

Example: A restaurant owner ignores a small leak under the sink, leading to mold and warped flooring over time. When they finally file a claim, the insurer denies it, stating that the damage resulted from long-term neglect rather than an unexpected event.

3. Wear and Tear-Related Damages Are Not Covered

How It Works

Commercial property insurance does not cover aging infrastructure, deteriorating plumbing, or failing equipment due to normal use. Businesses are expected to maintain and replace worn-out systems before they cause damage.

Why It’s Important

• Reinforces the need for proactive maintenance
• Ensures insurance only covers unexpected incidents, not avoidable failures
• This prevents businesses from relying on insurance to fix neglected systems

Example: An old roof has developed multiple leaks due to worn-out shingles. When water damage occurs inside the building, the insurance agent or companies to deny the claim, stating that the roof was in poor condition and should have been replaced earlier.

Understanding these exclusions ensures your business is not caught off guard when filing a claim. 

If your property is at risk for floods, sewer backups, or gradual leaks, consider additional coverage options and maintain your infrastructure to prevent costly out-of-pocket repairs.

Preventive Measures for Water Damage

Water damage might lead to costly repairs and business disruptions, but many incidents are avoidable with proper prevention strategies. Commercial property insurance covers sudden and accidental damage, but claims may be denied if the damage results from neglect or poor maintenance. Taking proactive steps can help businesses reduce the risk of water damage, maintain coverage eligibility, and prevent financial losses.

1. Regular Maintenance and System Inspections

Routine plumbing, HVAC, and roofing inspections help identify minor issues before they become major problems. Regular maintenance reduces the likelihood of pipe bursts, leaks, or equipment failures that could lead to significant water damage.

Why It’s Important

• Detects small leaks early before they cause major damage
• Prevents pipe corrosion, blocked drains, and HVAC failures
• Ensures compliance with insurance requirements for maintenance

2. Understanding Property-Specific Risks

Each business has unique water damage risks based on location, building structure, and operational needs. Identifying these vulnerabilities allows for targeted prevention measures, such as installing flood barriers or upgrading old plumbing systems.

Why It’s Important

• Helps businesses customize preventive measures based on risk level
• Reduces exposure to severe weather-related water damage
• Ensures property improvements align with insurance policy requirements

3. Training Employees on Risk Identification

Employees are the first line of defense against water damage. Training staff to recognize early warning signs—such as damp walls, unusual odors, or dripping water—allows businesses to address issues before they escalate.

Why It’s Important

• Encourages early reporting of leaks and potential hazards
• Prevents operational disruptions due to undetected water damage
• Ensures compliance with business safety and maintenance protocols

Businesses can avoid costly repairs, maintain insurance eligibility, and ensure smooth operations by taking these steps.

Additional Insurance Policies and Combined Coverage Options

Standard commercial property insurance may not cover all types of water damage. Adding specialized policies or bundling coverage through a Business Owners Policy (BOP) can provide better protection and cost savings.

• Flood Insurance: Covers damage from natural flooding due to storms, overflowing rivers, or heavy rainfall. Required in high-risk flood zones. Available through NFIP or private insurers. Helps cover building repairs, damaged inventory, and cleanup costs.
  
  
• Sewer or Drain Backup Coverage: Protects against water damage from backed-up sewer lines, drains, or sump pumps. Not included in standard property policies. Covers cleanup, sanitization, and repairs. Prevents costly property damage and business disruptions.
  
  
• Business Interruption Insurance: Get the financial support if a business must close temporarily due to covered water damage. Covers lost revenue while repairs are made. Helps with ongoing expenses like rent, utilities, and payroll. It may include relocation costs. Often bundled in a Business Owners Policy (BOP).
  
  
• Equipment Breakdown Insurance: Covers water damage caused by sudden equipment failures. Protects HVAC systems, boilers, and refrigeration units. Pays for repairs and related business losses. Essential for businesses reliant on climate control or machinery.
  
  
• Business Owners Policy (BOP): Bundles multiple coverages for broader protection. Includes commercial property, liability, and business interruption insurance. Reduces premium costs compared to purchasing separate policies. Simplifies insurance management with a single policy.

Adding flood, sewer backup, and business interruption insurance ensures full protection against water damage risks. Bundling coverage in a BOP provides better coverage at a lower cost, making it a smart choice for businesses.

Making Sure Your Coverage Is Sufficient

Water damage risks evolve, and a policy that once provided sufficient protection may no longer meet a business’s needs. Regularly reviewing coverage, adjusting limits, and considering additional protection ensures businesses stay prepared for unexpected water damage incidents.

• Regular Policy Reviews: Coverage should be reviewed annually to ensure it aligns with current property values and business assets. Helps avoid underinsurance in case of major water damage.
• Adjusting Coverage Based on Location: Businesses in flood-prone or extreme weather areas may need additional protection. High-risk locations may require flood or sewer backup insurance for full coverage.
• Increasing Coverage for Business Growth: Expanding businesses with new equipment or inventory may need higher coverage limits. Ensures that water damage claims cover full replacement costs.
• Understanding Policy Limits and Exclusions: Knowing what is covered and excluded helps prevent unexpected claim denials. Helps businesses determine if endorsements or separate policies are necessary.
• Working with an Insurance Advisor: Consulting an insurance expert TWFG Khan Insurance, helps identify coverage gaps and ensure the right policies are in place. Prevents financial losses due to inadequate protection.
