Chimney Collapse Hazards & Chimney Support & Bracing Requirements

Depending chimney height and on where and how they were constructed, both masonry and metal chimneys both may require lateral support (ties to the building) as well as bracing at the rooftop to avoid the very serious hazards of collapsing chimneys. A collapsing chimney is not just a potential fire or carbon monoxide risk.

The heavy weight of collapsing masonry chimneys can be fatal if they fall onto occupants. Chimneys may collapse from any of a number of reasons:

  • Damaged masonry chimneys from frost or water
  • Chimneys with inadequate footing
  • Chimneys with inadequate lateral support
  • Chimneys lacking reinforcement in earthquake prone areas
