The sky turns dark purple, air pressure plunges, and gusts rattle exterior windows across Central Missouri. Most property owners wait until this exact moment to look for flashlights and wonder whether the basement will stay dry. When severe weather develops across the Ozarks, delayed preparation often leads directly to water intrusion, roof failure, and expensive structural repairs.
To protect your property before a severe storm, clear loose yard debris, clean gutters and downspouts, test sump pumps, and secure doors and windows. Move indoor valuables away from exterior walls, shut all interior doors, and document your building baseline condition with dated photos before strong winds and heavy rainfall arrive.
Taking deliberate steps hours before severe weather strikes gives your building envelope the best chance to hold up under high winds, hail, and torrential rain. Knowing what to do before a storm keeps your family or staff safe while limiting costly downtime.

Severe weather rarely follows a convenient schedule. Frontal boundaries moving across Missouri can produce severe thunderstorms and tornadoes with only a few hours of warning. Breaking your preparation into distinct time windows helps you finish high-priority exterior tasks while conditions are still dry.
When the National Weather Service issues a severe storm watch, focus on structural integrity and system diagnostics. This 48-hour window provides enough daylight to inspect elevated rooflines and make quick trips to the hardware store for supplies.
When regional radar shows squall lines moving into your county, stop exterior ladder work immediately. Shift your attention entirely to personal safety and securing structural openings.
High wind exploits every loose seam on a structure. A cracked piece of siding, an unsecured gate, or loose metal flashing can turn moderate squalls into an active building breach. Start your exterior walkthrough at the outer property boundary and work inward toward your foundation.
Dead branches hanging over rooflines represent an immediate hazard during squalls. Limbs thicker than 2 inches can snap under 45 mph gusts, puncturing decking and ceiling joists. While major tree work requires professional arborists, cutting down dry, loose limbs within reach before the storm arrives prevents heavy impact damage.
Water always follows the path of least resistance. During intense downpours, residential basements and ground-floor commercial units face heavy hydraulic pressure from saturated soil and backed-up storm sewers.
| System Component | Residential Action Item | Commercial Facility Action Item |
|---|---|---|
| Sump Pump Assembly | Pour 5 gallons of water into the crock; verify float switch and backup battery fire. | Test dual-pump mechanical station; inspect auxiliary generator automatic transfer switch. |
| Electrical Main | Locate main breaker disconnect; elevate ground-level surge strips at least 12 inches. | Lock out non-essential floor subpanels; elevate critical server racks and battery backups. |
| Sewer Cleanout | Inspect main sewer backwater valve for grit and clear mechanical obstructions. | Test industrial backflow check valves on lower-level plumbing and commercial grease lines. |
| HVAC & Compressors | Strap ground condenser to pad; shield top fan housing against wind-blown debris. | Bolt down rooftop economizer panels; close fresh air intake dampers against driving rain. |
Test your sump pump system by pouring five gallons of water directly into the basin. The float should rise smoothly, start the pump motor within two seconds, and discharge the water outside without hesitation. If the float catches or the motor hums without moving water, clear the intake screen before rainfall starts.
If your property sits in a low-lying valley or near lakefront drainage channels, stack sandbags around basement window wells and below-grade entryways. Place bags in an overlapping pyramid pattern, folding the top flap inward to divert surface water away from the foundation.

Commercial buildings have distinct structural vulnerabilities, including wide flat roofs, expansive storefront glass, and complex utility setups. Preparing a commercial property requires operational planning along with physical reinforcement.
Flat commercial roofs depend on roof drains and edge scuppers to shed thousands of gallons of water. When fallen leaves or windblown trash block a 4-inch drain during a storm, water pools rapidly. A single inch of standing water weighs roughly 5.2 pounds per square foot. That added weight stresses structural steel trusses and can cause interior ceiling collapse. Direct your maintenance team to clear all rooftop drain screens at least 24 hours before a forecast storm.
Business operators must also safeguard physical equipment, client records, and merchandise. Move desktop computers, copiers, and inventory at least 10 feet away from exterior perimeter windows. Lift floor-level boxed stock onto wooden pallets at least 4 inches off the floor to prevent moisture damage from flash seepage. If you manage retail plazas or multi-tenant offices, understanding how different property types handle weather risks will help you identify weak spots ahead of time.
Establishing an emergency plan with a company providing commercial restoration and cleaning services ensures your business receives priority dispatch, temporary power, and structural drying if a severe storm disrupts operations.
Insurance claims move much faster when property owners can demonstrate the exact condition of their real estate and personal assets before the damage occurred. Adjusters evaluate the physical evidence after an event, so clear baseline records eliminate disputes regarding pre-existing wear.
Spend 20 minutes completing a high-resolution photo and video walkthrough of your property. Stand in the corner of each room to take wide-angle photos, then take clear close-ups of major appliances, HVAC data plates, electrical panels, and serial numbers. Open kitchen cabinets, commercial supply closets, and storage racks during your walk.
Outside, photograph all four exterior elevations, including the roofline, gutters, siding, outbuildings, and paved driveways. Store these digital files in a dedicated cloud folder alongside your insurance policy declarations page, agent contact numbers, and building floor plans. Keeping paper copies inside a waterproof lockbox ensures access even if cellular towers lose power.
Taking thorough photos protects your coverage if wind-driven rain penetrates your roof and requires immediate emergency water damage mitigation to dry out drywall, carpeting, and structural framing.
After completing exterior and mechanical checks, focus on the interior living and working areas. If severe winds shatter an exterior window or tornadic gusts cause structural uplift, smart interior staging protects occupants and limits water spread.
Pick a windowless interior room on the lowest level, such as a hallway, utility room, or reinforced bathroom, as your safe zone. Equip this area with a 72-hour emergency supply kit containing one gallon of water per person per day, non-perishable food, flashlights, extra batteries, a NOAA weather radio, and a first-aid kit.
Close all interior solid-core doors across the entire building. Closing interior doors divides your building into small structural compartments. If wind breaks a window on the windward side, closed doors restrict internal air pressure from pushing upward against the roof deck, reducing the risk of roof separation.
Pull furniture, office desks, electronics, and inventory toward the center of the room, keeping them at least 6 feet away from outside walls. If wind-driven rain forces its way past window seals, this buffer prevents water from soaking your most valuable items.
Effective storm preparation begins with simple maintenance tasks that you can complete in an afternoon. Start by clearing roof drains, testing your sump pump with five gallons of water, and capturing a complete video inventory of your building interior.
If severe weather causes structural openings, water leaks, or fallen tree impacts on your property, call U.S. Disaster Restoration. Our IICRC-certified crews provide 24/7 response across Central Missouri to secure structural openings, extract water, and provide complete reconstruction services to return your property to pre-loss condition.
How far in advance should I start storm preparations?
Start exterior maintenance tasks 48 hours before an anticipated storm by clearing yard items, cleaning downspouts, and testing backup generators. Complete interior shelter staging and secure window openings at least two hours before the weather front arrives.
What is the single most important interior step before a severe storm?
Close every interior door throughout the building. Closed interior doors compartmentalize air pressure if exterior windows fail, which significantly reduces upward aerodynamic pressure on your roof framing and limits the spread of wind-driven water.
How should I store baseline property documentation?
Upload high-resolution photos, equipment serial numbers, and insurance policy documents directly to an encrypted cloud storage platform. Keep printed copies of your emergency contacts and policy numbers inside a waterproof, portable lockbox on site.
