01 · Weather and maintenance
Look from the ground
From a safe location, note a missing cap, visible debris, a bent metal termination, fallen masonry pieces or new water marks indoors. Use binoculars or a phone zoom if useful, but do not climb onto a wet, icy or damaged roof.
02 · Weather and maintenance
Save the timing
Write down when the storm occurred and when you noticed a change. Photograph the visible condition and keep any roof or insurance inspection notes. Tell a contractor if a tree, branch, hail or nearby impact may have affected the chimney.
03 · Weather and maintenance
Know when to stop
If you see structural movement, falling debris, smoke leakage or an alarm, keep people clear and contact emergency services or a qualified professional as appropriate. Do not use a system when you suspect it has been damaged until it is assessed.
Keep the right safety boundary
This guide is general homeowner education. Standards, permit rules and manufacturer instructions change. Ask a qualified professional to assess the actual chimney, flue and appliance. For an active alarm, suspected fire or possible carbon-monoxide exposure, get outside and contact emergency services.
Read the CSIA homeowner resources or the CPSC carbon-monoxide guidance.
