Protecting Office Buildings From Destructive Storm Damage
Last updated October 25, 2026
The short answer
Start with the Roof and Exterior
The roof is the first line of defense against heavy rain and hail. Inspect it before storm season for loose shingles, cracks, or worn flashing. Repair any weak spots, and clear gutters and downspouts so water flows away from the building.
Windows and exterior doors should seal tightly. Check caulking and weather stripping, and replace any that is cracked. If your area is prone to hail, consider impact-resistant glass or protective film. Secure outdoor furniture, signs, and equipment that wind could turn into projectiles.
- Trim tree branches that overhang the building
- Anchor rooftop equipment like HVAC units
- Install backflow valves on drains
- Keep a supply of plywood to board up windows
- Check the roof for ponding water after heavy rain
Plan Your Interior Defenses
Inside the building, move important electronics and files away from windows and off the floor. Use plastic sheeting to cover computers and servers if a leak is likely. Elevate equipment on pallets or shelving to keep it dry.
Identify the main water shutoff valve and make sure people know where it is. If a pipe bursts during a storm, shutting off the water quickly can limit damage. Also, have a plan for shutting down power if water enters the building.
Backup Power and Data Protection
Storms often cause power outages, which can disrupt business and damage electronics. Install an uninterruptible power supply for critical systems, and consider a generator for longer outages. Test backup systems regularly.
Back up data to an off-site cloud service or external drive. Store backups in a different location so a single storm event won't destroy both the originals and the copies. Keep a printed list of emergency contacts, including your insurance company and the pros.
Act Fast After the Storm
After the storm passes, inspect the building for damage. Look for water stains, damp carpets, and standing water. The sooner you address moisture, the less likely mold will grow. Move wet items to a dry area and use fans to promote airflow.
If water damage is significant, contact the pros for help. They can extract water, dry the structure, and restore affected materials. Do not enter a flooded area if you suspect electrical hazards or structural damage. See a doctor if you feel unwell from mold exposure.
Understand Your Insurance Coverage
Review your commercial property insurance policy before a storm hits. Know what types of damage are covered, such as wind, hail, or flood. Flood damage is often excluded and may require separate coverage.
Document damage with photos and keep receipts for any emergency repairs. Policies vary, and your insurer decides what is covered. Contact your insurance company promptly to start the claims process.

How can I prevent roof leaks during a storm?
Inspect the roof before storm season and repair any damaged shingles or flashing. Clear gutters and downspouts to prevent water backup. Consider applying a waterproof coating if recommended by a roofing professional. Regular maintenance is the right prevention.
What should I do if water enters my office?
Turn off the power if it is safe to do so, and shut off the water supply if the leak is from a pipe. Move valuable items to a dry area and start drying the space with fans and dehumidifiers. Contact the pros quickly to assess the situation.
Are storm-related damages covered by insurance?
Coverage depends on your specific policy. Wind and hail damage is often covered, but flood damage may not be. Check your policy and consider adding flood insurance if you are in a flood-prone area. Policies vary, and your insurer decides what is covered.
