Chimneys take more punishment during a storm than almost any other part of a roof, standing proud of the roofline and bearing the full force of wind that a lower, sloped surface is largely designed to deflect. It's not unusual for a chimney to come through a severe weather event with problems that aren't obvious from the ground but matter a great deal once winter rain sets in, which is why they're worth a closer look after any significant storm affecting Ridgeway rather than treated as an afterthought once the immediate weather has passed.
Flashing around the base of the chimney, where it meets the roof, is one of the most common failure points. Wind can lift or split this seal over time, and once it's compromised, water tends to track down inside the chimney breast rather than showing itself immediately, meaning the first sign indoors might be a damp patch weeks after the actual storm rather than an obvious drip appearing on the day itself while the wind is still blowing. Because the damp tends to develop gradually, it's easy to mistake the first faint staining for an unrelated issue rather than connecting it back to the storm that caused it weeks before.
Pointing between the bricks of the chimney stack can also crack or crumble under wind pressure and repeated wetting, particularly on older stacks, allowing moisture to penetrate the masonry itself and gradually weaken it from within. Chimney pots can crack or shift, and in more severe cases a stack that was already weakened can be knocked further out of true, which is a structural concern rather than just a cosmetic one and needs a proper assessment rather than a quick sealant fix applied in a hurry. A stack that leans even slightly can put uneven weight on the roof structure beneath it, which is one reason a wobble or visible lean should never simply be left to monitor.
Because a chimney sits at height and often out of easy view, many of these problems only get noticed when there's already a leak or a visible sign of damage inside the loft or on a bedroom ceiling below the chimney breast. Regular checking after storms, rather than waiting for symptoms, tends to catch problems while they're still a straightforward repair rather than a more involved one requiring extensive brickwork or a full rebuild of part of the stack. Simple checks such as looking for crumbled mortar on the ground near the base of the chimney, or fresh cracks appearing in ceiling plaster below it, can give an early clue that something needs a closer look.
A proper post-storm chimney check covers the flashing, the pointing, the pots and capping, and the general stability of the stack, since a fault in any one of these can lead to water ingress or, in the more serious cases, a genuine safety concern that needs addressing without delay by someone qualified to work safely at that height and with the right equipment.
