The short answer

Wait for the All Clear

Before you step outside, listen to local news or emergency alerts. Tornadoes can leave behind downed power lines, broken gas mains, and unstable structures. Even if your home looks fine, the area around it may not be safe. Local officials will tell you when it's okay to return and assess.

If you smell gas or hear a hissing sound, leave the area immediately and call the gas company from a safe distance. Do not touch any wires, and do not enter a building that shows signs of structural collapse. Your health and safety are more important than checking on your property.

  • Listen for emergency broadcasts before going outside
  • Watch for downed power lines and avoid touching them
  • Smell for gas or hear a hiss, then evacuate and call for help
  • Check for leaning walls or sagging roofs from a distance
  • Keep children and pets indoors until you're sure it's safe
  • Wear sturdy shoes and gloves when you do go out

Document Visible Damage

Once you're outside, take photos and videos of everything you see. Capture the roof, siding, windows, doors, and any debris that hit your home. Also photograph your yard, fence, and nearby structures. This record helps you remember details and supports any insurance claim you might file later.

Write down the date and time of the damage. Note any missing shingles, broken glass, or water stains you can see from the ground. Do not climb onto the roof or enter a room with a sagging ceiling. A visual record is enough for now; a professional can do a closer look later.

Check for Water Entry

Tornadoes often bring heavy rain, so water damage is a real risk. Look for wet spots on ceilings, walls, and floors, especially near windows and doors. Check your basement or crawlspace for standing water. If you find any, it's important to address it quickly to prevent mold growth.

Water damage can be hidden behind walls or under flooring. If you notice a musty smell or see discoloration, that's a sign of moisture. Local water damage pros can use moisture meters to find hidden water. They can also help dry out your home and prevent further issues, but you need to act fast.

  • Inspect ceilings and walls for water stains or drips
  • Feel carpets and drywall for dampness
  • Look for standing water in the basement or crawlspace
  • Notice any musty odors that suggest hidden moisture
  • Check around windows and doors for leaks
  • Document any water signs with photos

Prioritize Safety Hazards

Your main job is to spot dangers, not to fix them. If you see a cracked foundation, leaning chimney, or broken gas line, keep your distance. These are serious hazards that need professional attention. A structural engineer or a qualified contractor can assess the stability of your home.

If you have a gas shutoff valve and know how to use it, you can turn it off if you suspect a leak. But only do this if you can reach the valve safely. If you're unsure, leave it and call the gas company. Similarly, if you see exposed wiring, turn off the main power only if it's safe to do so.

Get a Professional Inspection

After you've done your own walkthrough, it's wise to have a professional look at the damage. A home inspector or a structural engineer can identify issues you might miss, like roof damage or foundation cracks. They can give you a detailed report that helps you decide what to fix first.

For water damage specifically, the pros can perform a thorough inspection. They use specialized tools to detect moisture behind walls and under floors. Early detection can save you from costly repairs later.

Frequently asked questions

What should I do immediately after a tornado?

First, stay safe. Wait for local officials to say it's clear. Then, check for gas leaks or downed power lines from a distance. Document damage with photos, and avoid entering any structure that looks unstable. If you see water, note it, but don't wade in if there's a risk of electrical shock.

How can I tell if my roof is damaged?

From the ground, look for missing shingles, exposed underlayment, or dents on flashing. Also check for granules in your gutters, which indicate shingle wear. If you see any damage, don't climb up yourself. A roofing professional can safely inspect it and tell you if repairs are needed.

Is water damage covered by insurance?

Policies vary, and your insurer decides what is covered. Tornado damage, including wind-driven rain, is often covered, but you need to check your specific policy. Document all damage with photos and call your insurance company to file a claim. They will send an adjuster to assess the damage.
