A Proactive Checklist for Property Managers and Business Owners to Prevent Flood and Wind Damage
Summer storms are no joke. With intense rain, high winds, flash floods, and even tornado threats becoming more common across many regions, storm season can cause severe and costly damage to commercial buildings. For property managers and business owners, preparation isn’t just a precaution — it’s essential protection for your tenants, assets, and bottom line.
Fortunately, there are steps you can take right now to minimize damage before the first storm hits. This checklist will walk you through key areas of your building to inspect, update, and secure so you can weather the season with confidence.
Why Storm Preparation Matters for Commercial Buildings
Storms don’t discriminate. Office buildings, retail stores, apartment complexes, and industrial facilities are all vulnerable to floodwater, roof damage, power outages, and structural issues. Here’s why preparing ahead of time is so critical:
- Property Damage Is Expensive: Flood and wind damage can cost tens of thousands of dollars — and insurance may not cover everything.
- Downtime Can Be Devastating: Every day your business is closed due to storm damage means lost revenue and productivity.
- Safety Is on the Line: Flying debris, broken windows, and electrical hazards can pose serious risks to employees, tenants, and customers.
- Insurance Claims Go More Smoothly: Proactive documentation and mitigation efforts can help you navigate claims faster and more successfully.
Storms are unpredictable, but your response doesn’t have to be. Let’s get into the checklist.
Storm Preparation Checklist for Commercial Properties
1. Inspect Your Roof and Drainage System
Your roof is the first line of defense against wind and water — and often the first point of failure.
✅ Schedule a Professional Roof Inspection: Look for missing or damaged shingles, signs of water pooling, soft spots, or punctures. Commercial flat roofs are particularly vulnerable to ponding.
✅ Clean Gutters and Downspouts: Blocked drainage leads to water buildup and potential leaks. Ensure water is directed away from the foundation.
✅ Install Gutter Guards: Prevent future clogs by adding guards that keep leaves and debris out of your gutter system.
✅ Check for Loose Flashing or Vents: Secure all roof components to prevent them from becoming windborne debris.
2. Secure Windows and Doors
Broken windows and compromised door seals are entry points for both wind and rain.
✅ Inspect for Cracks or Weak Seals: Reinforce or replace damaged weather stripping, caulking, or gaskets around doors and windows.
✅ Install Storm Shutters or Impact-Resistant Glass: Especially in high-risk regions, these upgrades offer added protection.
✅ Test Automatic Doors: Ensure they seal and close properly under power loss scenarios.
3. Check the Building’s Perimeter and Landscaping
What’s outside your building can be just as hazardous as what’s inside during a storm.
✅ Trim Trees and Remove Dead Branches: Overhanging limbs can fall on your roof or power lines.
✅ Secure or Store Outdoor Furniture and Equipment: Loose items can become dangerous projectiles.
✅ Inspect Parking Lot and Storm Drains: Ensure that water drains properly away from the building and that grates are clear.
✅ Grade Your Property: If possible, adjust grading to divert water away from the foundation.
4. Inspect and Protect HVAC and Utility Systems
Critical systems like heating, cooling, and power should be reinforced against storm threats.
✅ Elevate HVAC Units: Especially in flood-prone areas, elevating ground units reduces the risk of water damage.
✅ Secure Exterior Utility Boxes: Strong winds can damage exposed meters and boxes. Reinforce or shield as needed.
✅ Inspect Backup Generators: Test all backup power systems, change filters, and ensure fuel is fresh.
✅ Label and Map Shutoffs: Make sure all emergency shutoff valves for gas, water, and electricity are clearly labeled and accessible.
5. Review Flood Prevention and Water Infiltration Controls
Flooding is one of the most common causes of damage during summer storms.
✅ Install or Service Sump Pumps: Ensure sump pumps are operational and have battery backups in place.
✅ Seal Cracks in Foundation or Basement Walls: Water intrusion can begin with the smallest cracks.
✅ Consider Flood Barriers or Sandbags: If your property is in a flood zone, having quick-deploy flood barriers on hand can reduce major water damage.
✅ Check for Backflow Prevention Devices: Municipal storm surges can push wastewater into buildings. Make sure your plumbing is protected.
6. Update Your Emergency Preparedness Plan
Every building should have a documented plan for emergencies — and everyone should know it.
✅ Review Evacuation Routes and Exit Maps: Post visible signage in key areas and verify that exits are clear and operational.
✅ Train Staff or Tenants on Emergency Procedures: Hold drills if appropriate and update emergency contact lists.
✅ Store Emergency Supplies On-Site: Include flashlights, batteries, first aid kits, bottled water, non-perishable food, and blankets.
✅ Verify Alarm Systems and Fire Sprinklers: Ensure all warning and suppression systems are up to code and functioning.
7. Back Up Important Data and Documents
If your building loses power or suffers physical damage, your business data should remain safe.
✅ Digitize Paper Records: Back up files and store them in cloud-based or off-site systems.
✅ Secure On-Site Servers: Elevate or shield servers against flood risks and power surges.
✅ Implement a Continuity Plan: Know how your business or property operations will resume after a storm.
8. Document Your Property for Insurance
Before disaster strikes, detailed records can make insurance claims much easier.
✅ Take Photos and Videos of Key Areas: Document your roof, HVAC systems, windows, and interiors.
✅ Keep Inventory Lists: For equipment-heavy businesses, detailed asset tracking is crucial.
✅ Store Insurance Policy Information in Multiple Locations: Make digital copies accessible remotely.
✅ Review Your Coverage: Ensure you’re adequately covered for flood, wind, and business interruption.
What to Do Immediately Before a Storm
If a major storm is forecasted within 24–48 hours:
- Secure all loose exterior items.
- Move valuables and electronics off the ground.
- Close and lock all windows and doors.
- Notify tenants or employees of procedures.
- Shut down unnecessary power systems.
- Deploy sandbags or barriers if flood risk is high.
