Why flashing faults need proper detail work
Junctions checked fully
We inspect the lead and the roof detail it is meant to protect.
Repair by condition
Patching, refixing or renewal depends on how the lead has failed.
Movement allowed for
Good dressing helps leadwork cope with normal expansion and weather.
Stopping water at the roof junction
Lead flashing has a simple job, but when it fails, water can travel a long way before it shows indoors. We carry out lead flashing repair work in Deeside at roof changes and junctions around chimneys, walls and other projections where the covering needs a flexible, weatherproof seal. Typical faults include lifting edges, splits, poor laps, failed joints and sections that have pulled away from the chase. Those defects can look small from the ground, yet still let plenty of rain behind the covering. We inspect the lead itself and the surfaces it meets, because a good flashing repair depends on the full junction working together, not just on patching the metal.
Choosing the right repair for your leadwork
Some flashing faults respond well to a local repair. Others need a section refixed or renewed because the lead has split, distorted or lost its hold entirely. We decide that by looking at the condition of the lead, the extent of the failure and the state of the materials beside it. Correct shaping, overlap and dressing are important because the lead has to shed water while still allowing for normal movement. If the flashing is repaired without that care, the leak often returns at the next weak spot. Our aim is to leave the junction behaving properly again, not just looking neater for a few weeks.
Frequently asked questions
Can lead flashing be repaired instead of replaced?
Often, yes, if the problem is local and the rest of the lead remains sound. We assess whether the fault needs a patch, a refix or a renewed section. If the material has split widely or pulled away over a longer area, a bigger repair may be the safer option.
Why do leaks appear around chimneys and walls?
Those junctions rely on flashing to bridge between different materials and shed water away from the opening. If the lead lifts, splits, loses its chase or was never lapped well in the first place, rain can track behind it and show indoors some distance away.
Do you inspect the materials beside the flashing too?
Yes. Flashing works with the brickwork, render or roof covering around it, so we check the full area. A lead repair will not last well if the adjoining detail has also broken down and is still giving water another way in.
