Restore the roof's exposed transition points
All sides considered
We assess the front, sides and rear drainage details around the chimney.
Roof covering reinstated
We reconnect surrounding tiles or slates carefully after fitting the new lead.
Drainage path restored
We shape the flashing so that rainwater is safely returned to the roof covering
Keep water moving safely around roof junctions
The point where a chimney passes through the roof contains several hard-working weatherproof details. Front aprons, stepped flashing, soakers and back gutters each direct rain away from a different part of the junction. If lead splits, lifts or deteriorates, water can enter through a small opening and travel into the roof layers.
We inspect the complete chimney junction rather than focusing only on the most visible strip, as water staining may appear away from the original opening. We also assess lead flashing around walls, roof projections, changes in level and other transitions where the main roof covering is interrupted. Splits, lifted edges, open joints and poor dressing can all create routes for rainwater.
Replacement leadwork shaped to the roof
Leadwork must fit the roof covering, chimney and expected water flow while allowing for normal movement. Where replacement is required, we remove failed leadwork, prepare the adjoining surfaces and shape each new detail for its specific role, with suitable laps, fixings and allowance for movement. Surrounding tiles or slates may need careful lifting so the new lead can connect correctly rather than being laid over a defective arrangement.
Wills Brothers Roofing Limited will dress the replacement to guide water onto the roof's drainage plane, then reinstate disturbed materials and check the full transition. The apron, side details and rear channel are treated as one connected system, helping avoid fixing one opening while leaving another weak point untouched. This approach provides a properly functioning junction rather than simply covering the visible defect.
Frequently asked questions
What areas of a roof can leadwork protect?
Leadwork can be used around chimney stacks, roof-to-wall junctions, changes in roof level and other areas where the main roof covering is interrupted. Each detail is formed to direct water safely away from the junction.
How do I know if my roof flashing needs replacing?
Splits, lifted edges, open joints, deteriorated lead and water staining around a junction can all indicate a problem. We inspect the leadwork alongside the surrounding roof covering and masonry before recommending replacement.
Do you replace the surrounding tiles or slates when carrying out leadwork?
Where necessary, tiles or slates can be carefully lifted to allow the new leadwork to be correctly integrated. We then reinstate the disturbed materials and check that the completed junction provides a suitable route for water.
