What to do if…
a garage ceiling or roof structure is sagging and you are unsure if it is safe

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Keep everyone and pets out of the garage and away from its opening. Call 911 now if anyone is trapped or injured, material is falling, the structure is actively shifting or cracking, there is a fire or suspected gas leak, or people are in immediate danger.

Do not do these things

  • Do not go back inside to retrieve belongings.
  • Do not stand beneath the sagging area or reach through the garage opening.
  • Do not approach or operate the garage door if it appears distorted, is binding, or is beneath the sagging area.
  • Do not climb onto the roof or into an attic above the garage.
  • Do not add weight, move stored items, or puncture a bulging ceiling.
  • Do not try to brace, jack, or repair the structure yourself.
  • Do not enter the garage, stand in water, or approach the sagging area to reach an electrical panel.

What to do now

  1. Move to a safer pause. Get people and pets out of the garage and away from its opening. If damage, movement, or falling material extends beyond the garage, move farther away from that area too.
  2. Stop anyone from entering. From a safe location, tell other people not to use the garage. Put up a visible barrier or sign only if you can do so without approaching the hazard area.
  3. Call 911 for an immediate hazard. Call if anyone is trapped or injured, material is falling, the structure is actively shifting or cracking, there is a fire or suspected gas leak, or people are in immediate danger. Tell the dispatcher there is a possible structural-collapse hazard and whether the area has been cleared.
  4. Note visible changes only from a safe location. Do not enter to inspect the structure. If you can observe safely, note whether the sag is worsening, debris is falling, cracks are growing, repeated popping or cracking sounds are continuing, or the garage door frame is changing shape.
  5. Ask your local government how to report the unsafe structure. Use your local government website or main contact route and ask which office handles unsafe-building reports and inspections.
  6. Arrange an on-site safety assessment. Ask the local official which qualified person should assess the structure before anyone re-enters the garage.
  7. Treat water and electricity as hazards. If water or damaged wiring may be involved, switch off the affected circuit or main power only if you know how to do so safely from a dry location without entering or approaching the hazard area. Otherwise leave it alone and contact an electrician or emergency responders.
  8. Notify the responsible person promptly.
    • If you rent, tell your landlord or property manager that the garage is off-limits because of a possible structural hazard.
    • If you own the property, contact your insurer and ask what records they need.
  9. Document only from a safe location. Take photos or video only from outside the exclusion area. Note when the sagging started and whether there was a storm, heavy snow, a leak, recent work, or added storage weight.

What can wait

  • You do not need to work out the cause right now.
  • You do not need to retrieve belongings from the garage.
  • You do not need to choose a repair contractor or repair plan before the structure has been assessed.
  • You do not need to decide whether the garage can be used again until a qualified person confirms that it is safe.

Important reassurance

Stepping back is a reasonable protective response. You do not need to inspect the structure yourself or solve the whole problem immediately.

Scope note

These are first steps only. Later decisions about access, stabilization, repairs, permits, tenancy, or insurance may need help from the appropriate local authority or specialist.

Important note

This is general information, not legal, medical, financial, therapeutic, engineering, or other professional advice. If there is an immediate danger, call 911.
