Chapter 1
Follow the water path
Water near a fireplace does not automatically prove that porous brick is the source. Rain can enter around a cap, through crown cracks, at flashing, through wind-driven masonry exposure or from adjacent roofing. Condensation and plumbing or building-envelope issues can sometimes imitate a chimney leak.
Record when the symptom appears: during wind-driven rain, after snow melt, only while an appliance runs, or continuously. Timing is useful diagnostic evidence.
Chapter 2
Match the repair to the finding
Ask how the company isolated the likely path and whether another building component was ruled out. A proposal should identify preparation, materials, coverage, limitations and warranty. Generic coating should not replace repair of failed crown, flashing or mortar details.
- Cap fit and corrosion
- Crown slope, overhang and cracking
- Flashing laps and counterflashing
- Mortar joints and spalled units
- Attic or ceiling evidence
- Chase cover seams and rust
Chapter 3
Protect repairs with records
Photograph conditions before and after work, retain product names and invoices, and note the weather during any recurrence. Clear records help the contractor assess warranty questions and prevent future providers from starting with no history.
Field note: Do not inspect a wet or storm-damaged roof yourself. Use ground observations and qualified access.
