Top Causes of Water Damage & How to Prevent It: a practical guide for homeowners, property managers & building owners

Water Restoration

Water damage is one of the most common and costly problems facing both residential and commercial properties. According to national insurance data, about 1 in every 60 insured homes experiences a water damage or freezing related claim each year, and these losses make up roughly 24 to 28 percent of all property insurance claims. The average claim is nearly 14,000 dollars, which is just one reason prevention and quick response are so important.¹ ²

Whether you care for your own home or manage multiple buildings, understanding how water damage begins and how to prevent it can save valuable time, resources and stress. Here are some common causes and easy-to-follow tips for preventing water damage:

1. Plumbing Failures and Pipe Leaks

Burst pipes, aging plumbing and slow, hidden leaks remain the top cause of water damage in both homes and commercial buildings. Leaks behind walls or under floors often go unnoticed until moisture has spread into insulation, drywall or electrical systems.

Common causes of plumbing issues:

  • Corroded or aging supply lines
  • Poor pipe insulation
  • Shifting temperatures, especially during winter
  • Loose connections on sinks, toilets or appliances

Prevention tips:

  • Schedule annual plumbing inspections.
  • Insulate exposed or vulnerable pipes.
  • Add leak detection sensors near appliances and in lower levels.
  • Replace old plastic hoses with braided steel, especially on washing machines.

2. Roof Leaks and Drainage Issues

Roofing materials deteriorate over time. Storm damage, clogged gutters and worn flashing often lead to interior leaks that show up as stains on ceilings, peeling paint or mold.

Common causes of roof issues:

  • Missing or cracked shingles
  • Blocked gutters or downspouts
  • Damaged flashing
  • Ponding water on flat roofs

Prevention tips:

  • Inspect roofs twice a year and after major storms.
  • Keep gutters and downspouts free of debris.
  • Repair damaged roofing materials promptly.
  • Maintain rooftop HVAC units to avoid drainage backups.

3. Appliances and Equipment Failures

Water heaters, washing machines, dishwashers and ice makers can fail suddenly and cause significant flooding. In commercial buildings, mechanical room failures have a similar impact.

Common causes of appliance and equipment issues:

  • Appliance age
  • Faulty connectors or hoses
  • Hard water buildup
  • Poor maintenance

Prevention tips:

  • Replace appliances nearing the end of their service life.
  • Install drip pans beneath washers and water heaters.
  • Inspect hoses and connectors regularly.
  • Address unusual noises or vibrations quickly.

4. HVAC and Condensation Problems

Air conditioners, boilers and ventilation systems naturally create moisture. When lines clog or units malfunction, water can overflow into walls, attics or mechanical rooms.

Common causes of HVAC issues:

  • Blocked condensation lines
  • Dirty filters
  • Rusted drip pans
  • Improper drainage

Prevention tips:

  • Service HVAC systems seasonally.
  • Clear condensation lines.
  • Replace air filters on a routine schedule.
  • Look for signs of moisture around units.

5. Basement and Foundation Intrusion

Water intrusion through foundations, basements and crawl spaces is common in both older homes and commercial properties. Heavy rainfall or melting snow quickly exposes weaknesses in exterior drainage.

Common causes of water in basements:

  • Cracked foundations
  • Poor grading around the building
  • Failed sump pumps
  • Clogged exterior drains

Prevention tips:

  • Ensure soil slopes away from the property.
  • Test sump pumps and backup systems.
  • Seal foundation cracks.
  • Maintain French drains and exterior drainage paths.

6. Severe Weather and Natural Events

Storms, flash flooding and freezing temperatures frequently contribute to water losses. National data shows that more than 14,000 people in the United States experience a water damage emergency each day

Common causes of water damage following severe weather:

  • Frozen or burst pipes
  • Heavy rain overwhelming gutters or drains
  • Flooding that enters ground level areas
  • Wind driven rain entering weak building materials

Prevention tips:

  • Prepare before storm seasons and cold snaps.
  • Install backflow valves where needed.
  • Clear storm drains and gutters before major weather events.
  • Use temporary barriers or sandbags in high risk areas.
