The stain that returned after roof work

A homeowner notices a brown ceiling mark beside a chimney after several rainy days. The roof was recently repaired, but there is no chimney inspection record.

01 / OBSERVE

Preserve useful evidence

The useful record is a dated photograph, the timing of rainfall, the roof-work invoice and whether the mark fully dried between events. None of these proves that the roofer caused the leak.

02 / INVESTIGATE

Ask what the assessment should answer

A professional might examine flashing integration, the crown, cap and masonry, while considering a roof leak away from the chimney. Testing should be controlled and its limits explained. The work may require coordination between a roofer and chimney specialist.

03 / COMPARE

Different findings, different service paths

  • If flashing is the supported path, a defined roof-to-chimney repair may be appropriate.
  • If crown damage also contributes, a separate masonry scope may be needed.
  • If evidence is inconclusive, further diagnosis is more useful than promising a blanket coating.
Which observation connects this repair to the stain, and what remains uncertain?
04 / DECIDE

The lesson—not a promised outcome

There is no claimed repair result. The lesson is to purchase an evidence-backed scope, preserve the pre-work record and agree how recurrence will be assessed.
