What to do if…
a chimney pot, cap, or top section looks shifted after high winds and could fall

Short answer

Keep everyone away from the area beneath/around the chimney and stay off the roof. If it could fall onto people, a sidewalk, a driveway, or the street, call 911.

Do not do these things

  • Do not get on the roof, a ladder, or the chimney to “re-seat” or remove anything.
  • Do not stand directly under the chimney to look up or take pictures.
  • Do not keep using the fireplace/wood stove (or any appliance venting through that flue) until it’s inspected.
  • Do not try to “secure” it with tape/rope/weighting from below.
  • Do not delay if the risk is over a public area — falling masonry can be fatal.

What to do now

  1. Set a clear “no-go” zone.
    Keep people and pets well away from where debris could land (at least the height of the chimney, more if gusty). Don’t let anyone linger under eaves or along the wall below it.
  2. Move vehicles out of the fall zone only if you can do it without going underneath.
    If moving the car would put you under the chimney, don’t do it.
  3. If there’s immediate danger, call 911.
    Call if pieces are falling, the top looks unstable, or it threatens a sidewalk/shared walkway/driveway where people pass, or the street. Tell dispatch it’s a structural falling-debris hazard.
  4. Contact the responsible party for urgent make-safe work.
    • Homeowner: call a licensed roofing contractor or chimney professional for urgent inspection and stabilization/make-safe.
    • Renter: notify your landlord/property manager as an urgent safety issue.
    • Condo/townhome: notify your HOA/condo association if exterior structures are their responsibility.
  5. Stop using anything that vents through that chimney until it’s checked.
    A shifted top section can change draft and containment. Treat it as “do not use” for fireplaces/wood stoves/gas fireplaces tied to that flue until a pro clears it.
  6. If you suspect fumes or CO, act immediately.
    If you notice unusual exhaust smells, headaches/dizziness, or a CO alarm, get everyone outside to fresh air and call 911.
  7. Document safely for insurance and repairs.
    Take photos/video from ground level or a safe angle away from the fall zone. Note the time/date of the storm and any observed movement/noise.
  8. Avoid routes under the chimney.
    If the only entrance/exit is under the risk area, stay in a safer part of the home if you can. If you must leave for safety and there’s no safer exit, call 911 and ask for help getting out safely rather than walking under it.

What can wait

  • Picking the “best” long-term repair method (rebuild vs re-point vs new cap) — urgent stabilization comes first.
  • Detailed insurance discussions and multiple bids beyond the initial make-safe/inspection.
  • Cleaning up fallen fragments until overhead risk is controlled.

Important reassurance

You’re not overreacting — storm-shifted chimney parts can fail without warning. The safest plan is straightforward: clear the area, avoid the roof, and get qualified help to stabilize it.

Scope note

These are first steps only. Once it’s stable, a chimney professional may recommend a more detailed inspection (often described in recognized industry standards) before the system is used again.

Important note

This is general information, not professional advice. If there is an immediate falling-debris risk or anyone is in danger, call 911.
