Emergency Roof Repair: What to Do When Your Commercial Roof Leaks

Water is dripping through the ceiling. Employees are moving equipment, customers are noticing, and you need to act fast. A commercial roof leak can cause extensive damage in hours, but quick action can minimize losses. Here's exactly what to do.

Immediate Actions (First 15 Minutes)

  1. Move inventory, equipment, and electronics away from the affected area
  2. Place containers to catch dripping water
  3. Document the damage with photos and video for insurance
  4. If safe, check for electrical hazards near water
  5. Notify building occupants in the affected area

Safety First

If water is near electrical equipment or coming through light fixtures, turn off power to that area immediately. Water and electricity create life-threatening hazards.

Within the First Hour

  • Contact a commercial roofing contractor with emergency service capability
  • If you can safely access the roof, try to identify the water source
  • Notify your insurance company of the incident
  • Keep all damaged items for insurance documentation
  • Set up fans to begin drying affected areas

Finding the Leak Source

Water doesn't always drip directly below where it enters the roof. It can travel along insulation, decking, or structural members before dropping through the ceiling. Look for:

  • Obvious membrane damage visible on the roof surface
  • Failed flashings around HVAC units, vents, or skylights
  • Clogged drains causing ponding water
  • Separated seams in the roofing membrane
  • Damage around roof edges or parapet walls

Temporary Measures

While waiting for professional repair, some temporary measures can reduce water intrusion:

  • Tarping: A properly secured tarp can divert water away from a damaged area
  • Drain clearing: If ponding is visible, clearing blocked drains helps immediately
  • Sealant: For small visible cracks, roofing sealant provides temporary waterproofing

When Not to DIY

During active storms, wet conditions, or when the damage location is unclear, wait for professionals. Temporary rooftop work in unsafe conditions can result in injuries and may void your warranty.

Working with Your Insurance

Commercial property insurance typically covers sudden and accidental water damage, but documentation is essential:

  • Photograph and video everything before cleanup
  • Keep damaged inventory separate and documented
  • Save all repair invoices and estimates
  • Get the roofing contractor's written assessment of damage cause
  • File your claim promptly with all documentation

Preventing Future Emergencies

Most roof emergencies are preventable with regular maintenance. After your immediate situation is resolved, schedule a comprehensive roof inspection. Implement a maintenance program that includes regular inspections, prompt repair of minor issues, and clear drainage maintenance. The cost of prevention is a fraction of emergency repair and water damage restoration.
