Why this junction fails so often
A chimney and the surrounding roof move slightly differently over time, putting continuous strain on the flashing that bridges the gap between them — which is exactly why it's such a common failure point.
The tell-tale signs
Water stains on ceilings near the chimney, damp in the loft after rain, and lead visibly lifting away from the brickwork are the clearest indicators flashing has failed.
Why the damage often shows up elsewhere
Water from failed flashing frequently tracks along roof timbers before it shows as a stain, meaning the visible damage isn't always directly below where the actual problem is.
Repair or full replacement
Minor flashing issues can often be repaired in place. Where the lead has deteriorated more broadly, full replacement is the more reliable long-term fix rather than patching repeatedly.
How quickly it's usually sorted
Most flashing repairs are a single day's work, small compared to the water damage they prevent if left unaddressed.
