Chimneys stand higher than any other part of a Keynsham roof, which means they take the brunt of wind pressure during a storm, often showing damage before anywhere else on the property does. This can range from minor issues, such as a few loosened mortar joints, through to more serious problems like a stack that has begun to lean or is visibly shedding bricks, the latter of which should always be treated as an emergency given the risk of falling masonry. A quick visual check from ground level after any severe storm is a genuinely sensible habit to get into, and it costs nothing at all but a few spare minutes of your time.
Flashing around the base of a chimney is a particularly common casualty of high winds, since this lead detail is what keeps the junction between chimney and roof watertight, and it can be lifted, creased or torn even when the surrounding brickwork looks entirely fine. This kind of damage is deceptive because it rarely shows itself from ground level, and the first sign a homeowner in Keynsham gets is often a leak appearing indoors near the chimney breast, sometimes days after the storm that actually caused it. By that point, the damage may well have already spread considerably further than the original point of failure, making the eventual repair somewhat larger, slower and more costly than it needed to be.
Diagnosing whether a chimney problem is masonry-related, flashing-related, or both is an important first step, since the repair required is quite different in each case. Loose brickwork or damaged pointing generally needs repointing or, in more serious cases, partial rebuilding of the stack, while flashing damage is addressed by re-dressing or replacing the lead itself, and a thorough inspection will check both rather than assuming the problem is limited to whichever is more visible. Treating only one cause when both are genuinely present usually means facing a repeat leak indoors again before too long.
Because chimneys sit at height, safe access is central to doing this kind of repair properly, and depending on the property, this can mean a scaffold tower or other proper access equipment rather than relying on a ladder, both to protect the roofer carrying out the work and to allow a more complete inspection of the stack and its flashing than would be possible balancing at height.
Left unaddressed, both masonry and flashing damage around a chimney tend to worsen with each subsequent spell of wind and rain, since water finding its way into an already compromised joint or seal accelerates further deterioration.
