Chimneys are one of the most common sources of roof leaks after a storm, not because the brickwork itself has failed but because the flashing sealing the join between chimney and roof has been disturbed. This strip of lead, fitted where the chimney stack meets the tiled or slated surface, is designed to flex slightly but can still crack, lift, or pull away entirely when battered by strong wind, especially where it has already started to age.
For homes in Longwell Green with a chimney stack still in place, even if it is no longer used for a working fire, this junction remains one of the most vulnerable points on the whole roof. A gap of only a few millimetres in the flashing is enough to let water track down inside the chimney breast or along a rafter, often appearing as a stain on a bedroom ceiling or in a loft space well away from the chimney itself, which can make the source confusing to pin down without a proper inspection.
Because flashing failures are rarely visible without getting close to the roof, we treat any sign of a leak near a chimney as worth investigating quickly rather than waiting. Our emergency call-out lets us assess the stack, the flashing, and the surrounding tiles or slates together, since wind that has damaged flashing has often loosened nearby roof coverings too.
Where the existing lead has simply lifted or come away at a joint, a repair can often be carried out relatively quickly by refitting and resealing it properly. Where the flashing has degraded more significantly, perhaps after years of exposure before the storm finally finished it off, a full replacement using new leadwork gives a longer-term fix rather than a repeated patch job.
It also matters what type of flashing is involved, since not every chimney is finished the same way. Stepped flashing, dressed into the mortar joints up the sloped side of a stack, fails differently to an apron or saddle flashing across the front or back, and each needs a slightly different repair method to seat correctly. Getting this detail right the first time is part of why chimney flashing work is best left to someone experienced with the different configurations, rather than a generic sealant fix applied without regard to how the original detail was built. Cover flashing and soakers, tucked underneath the visible tiles at the sides of a stack, are worth checking too, since these hidden elements can fail quietly for some time before any sign reaches the surface.
Chimney flashing repairs are exactly the kind of job that benefits from being done properly the first time, since poor access equipment or rushed sealant work tends to fail again within a year or two.
