Pointing and masonry
Weathered joints or cracked details can let rain work into the roof junction.
Chimney Leaks
Chimney repairs and leaks
Chimney leaks can come from the stack, flashing, pointing or the surrounding roof covering, so the whole junction needs a careful look.
Chimneys are exposed from every side
A chimney has several vulnerable details in a small area. The stack, pointing, flashing, soakers, surrounding tiles or slates, and roof underlay all have to manage heavy rain and wind.
That is why chimney leaks are not always solved by looking at one mark indoors. The repair should trace how water is entering and where it is travelling before it appears.
Water shedding
Lead and flashing details need to guide water away from the chimney and roof covering.
Nearby coverings
Loose slates, tiles or roofline defects near the stack can look like a chimney problem.
Make the first inspection easier
Useful details include where damp appears, whether it follows a certain wind direction, whether the chimney has been repaired before, and whether any roof coverings look out of place from ground level.

Why do chimneys often leak?

What signs should I mention to a roofer?
Mention damp around the chimney breast, stains after wind-driven rain, loose roof coverings near the stack and any previous repair work.
