Traditional leadwork is a common feature on Henleaze's older properties, used around chimneys, valleys and roof junctions to keep water out of joints that would otherwise be vulnerable. It's durable material, often lasting decades, but it doesn't last forever, and storms have a way of exposing exactly where it's started to fail after years of quiet, unnoticed wear and gradual deterioration. Traditional lead is graded by thickness, referred to by code number, and using the correct grade for each application matters for how well a repair holds up over time.
Lead can fail in several ways over time: the mortar pointing that secures its top edge can crack and drop out, wind can lift or peel back an edge that's come loose, or repeated expansion and contraction through the seasons can eventually cause the lead itself to crease, thin and split at a stress point that's been building steadily for years without any obvious sign to the untrained eye. Soakers, small individual pieces of lead woven between tiles or slates at a junction, can fail independently of the main flashing and are worth checking separately during any repair.
Because leadwork typically sits at a junction, such as where a chimney meets the roof or where two roof slopes form a valley, a failure here can let in a disproportionate amount of water relative to the size of the fault, and that water often travels some distance inside the roof structure before it becomes visible as a leak or damp patch somewhere else entirely in the property. A lead valley that's been patched repeatedly over the years is sometimes better served by a full replacement of that section than another round of localised repairs. This is one of the reasons experienced roofers always trace a leak back to source rather than simply patching wherever water happens to be visible at the time.
An emergency repair usually starts with temporarily securing or patching the affected section to stop the immediate ingress, with a proper lead repair, or in some cases a full lead replacement on that section, carried out once access has been arranged, typically involving scaffolding on Henleaze's taller period properties with their steeper roof pitches. Where leadwork has been stolen or damaged deliberately, which does occasionally happen on accessible roofs, the repair process is broadly similar to fixing storm-related failure.
Replacing failed leadwork properly, rather than relying on sealant as a stopgap, is worth the extra effort, since sealant applied to old, worn lead tends not to hold for long once exposed to further weather and movement, meaning the leak often returns within a single season, sometimes worse than before. A properly dressed lead repair, shaped and finished by hand rather than simply sealed, tends to blend in far better with traditional roofing around it than a modern alternative.
