The junction most exposed to movement
A chimney and the surrounding roof structure move slightly differently over time and with temperature changes, putting ongoing strain on the flashing that seals the gap between them.
Water travels before it shows
A leak from chimney flashing often shows up as a stain some distance away, having tracked along roof timbers before finding a route through the ceiling.
Why it's easy to misdiagnose
Because the visible damage often isn't directly below the chimney, it's common for chimney flashing failures to be initially mistaken for a general roof leak.
A relatively small fix for a big problem
Compared to the water damage a failed flashing can cause over time, repairing or replacing chimney flashing is usually a straightforward, contained job.
