Post-Tornado Safety Check: What to Inspect First

Last updated October 25, 2026

The short answer

Check for Gas Leaks and Fire Hazards

The first thing to do after a tornado is check for the smell of gas. If you smell gas, leave the house right away and call the utility company from outside. Do not flip any switches or light matches, as a spark could ignite the gas.

Look for visible damage to gas lines, such as bent pipes or a hissing sound near your meter. Also check for downed power lines in your yard or on your home. Stay far away from any fallen wires and report them to the utility company.

  • Smell for gas near the meter and appliances
  • Listen for hissing sounds from pipes
  • Look for downed or sparking power lines
  • Avoid touching any standing water near wires
  • Turn off the main gas valve only if safe
  • Keep a flashlight ready, not candles

Inspect the Roof and Exterior Walls

After you confirm no immediate gas or electrical danger, walk around the outside of your home. Look for missing shingles, torn flashing, or holes in the roof. These openings can let rain in, especially in a hot, humid climate with frequent storms.

Check the exterior walls for cracks, shifts, or bowing. Pay attention to the corners where walls meet the roof and the foundation. If you see large cracks or the wall appears to lean, do not enter the house until a structural professional checks it.

  • Missing or lifted shingles
  • Torn or punctured roof membrane
  • Cracks wider than a quarter inch
  • Bowed or leaning walls
  • Broken windows or damaged frames
  • Gaps around doors and garage seals

Look for Water Intrusion Indoors

Once inside, check ceilings, walls, and floors for water stains or active drips. Tornadoes often bring heavy rain, so water can enter through roof damage or broken windows. Look for dark spots on drywall, peeling paint, or damp carpet.

If you find water, turn off the electricity in that room if it is safe to do so. Do not touch wet electrical outlets or appliances. Water damage can worsen quickly, so you may want to contact local water damage pros for an inspection and drying plan.

  • Dark or yellow stains on ceilings
  • Wet or sagging drywall
  • Damp carpet or buckled flooring
  • Water pooling near windows or doors
  • Musty odor in closed rooms
  • Visible mold spots on walls

Assess Electrical and Plumbing Systems

Check your electrical panel for tripped breakers or signs of water inside. If any outlets or switches feel warm or look scorched, turn off the main breaker if you can do so safely. Do not use any appliances that got wet until an electrician inspects them.

For plumbing, look for burst pipes, especially in crawl spaces or utility rooms. Tornadoes can shift foundations and crack pipes. If you see a leak, shut off the main water valve. A plumber can fix the pipe, and a water damage inspection can map the full extent of the moisture.

Document the Damage for Insurance

Take clear photos and videos of every damaged area before you start any cleanup. Capture wide shots of each room and close-ups of specific issues like cracks, water stains, or broken windows. This documentation helps your insurance company understand the claim.

Make a written list of damaged items, including furniture, appliances, and personal belongings. Note the approximate age and value of each item if you can. Policies vary, and your insurer decides what is covered. Keep all receipts for any temporary repairs you make, like tarping a roof.

Frequently asked questions

Should I stay in my home after a tornado?

Only stay if the structure is stable and there is no gas leak, active fire, or downed power line. If you see large cracks, sagging ceilings, or smell gas, leave and wait for a professional inspection. Your safety comes before saving belongings.

How do I know if my foundation is damaged?

Look for cracks wider than a quarter inch, especially near corners or where walls meet the floor. Check for doors or windows that stick or won't close, which can indicate shifting. If you notice these signs, have a structural professional examine the foundation before you sleep upstairs.

What should I do about wet drywall?

Do not cut it out yourself unless it is actively falling. Wet drywall can hide mold growth within 24 to 48 hours. You can use fans to dry the area, but contact a water damage inspection service to assess how deep the moisture goes and what needs removal.
