Stepped lead flashing at a roof-to-wall junction

OnPoint RoofCare · Lanarkshire & Glasgow

Lead Flashing Repairs & Replacement

Failed leadwork can allow water through chimney junctions, roof-to-wall joins and other exposed details. OnPoint RoofCare checks the affected connection and adjoining roof before recommending a local repair or renewal of the flashing. The aim is to address the route water is taking, not just cover the visible mark.

When to Ask About Lead Flashing Repairs & Replacement

Tell us what you have noticed and when it happens. These signs help guide the inspection; they do not establish the full repair from a photograph.

Split or lifted flashing
A gap where lead meets masonry
Damp near a chimney or roof-to-wall junction
Several sealant patches around the same connection

Send photographs taken safely from inside or ground level. Keep clear of loose material and leave roof access to appropriately equipped professionals.

Choosing the right work

A local repair or a renewed junction

An isolated defect in otherwise serviceable lead may be repairable. Where the sheet is widely split, distorted or repeatedly patched, renewing the affected detail can be more sensible. The decision should identify the precise section and explain what remains untouched.

SPAB’s roof-maintenance guidance describes both local repair and replacement approaches to damaged metal flashing. The method depends on the defect, material and arrangement; adding surface sealant is not a complete diagnosis.

Include the roof and masonry around the lead

Water can reach the back of a sound-looking flashing through an adjoining defect. We consider masonry joints, nearby slates or tiles and the drainage route as part of defining the work. Tell us when the leak appears and which repairs have already been tried.

The cost depends on height, access, the shape and extent of the leadwork and whether coverings must be lifted. Ask what reinstatement is included and how hidden damage will be reported. Photographs of accessible details can help explain the completed repair before those connections are covered again.

A defined scope

What Your Quote Can Include

The work is agreed from the findings. Depending on the property and required repair, the scope may include:

Inspecting the affected flashing and adjoining covering
Tracing visible openings and likely water routes
Assessing whether retained lead is suitable for repair
Forming agreed replacement sections and connections
Reinstating surrounding roof coverings within the quoted area

Height and access, the extent of damage, suitable materials and concealed layers affect the price. Ask what is included, what remains uncertain and how any additional work will be agreed.

Before you book

Lead Flashing Repairs & Replacement: Your Questions

Can you repair a small split?

Sometimes, where the surrounding lead and detail remain suitable. An inspection is needed to choose between a local repair and renewing the affected section.

Does a leak beside a chimney always mean bad leadwork?

No. Pointing, top weathering, pots and nearby roof coverings can also contribute. The proposed repair should follow the evidence.

Will the whole roof need lifting?

Not usually for an isolated junction repair, but the necessary access and reinstatement depend on the detail. The quotation should state the working area.
