Leadwork and flashing repairs for London roofs.

Roof tiles meeting a wall junction.
Contact Big Ben Roofing Ltd about leadwork and roof flashing in London. A split, gap or disturbed edge at a chimney, wall or valley can affect how the roof sheds rain. We can discuss the junction, identify the existing material and define whether a local repair or renewed detail is appropriate.
Junctions to describe in an enquiry
- Metal flashing or other details where a roof meets a wall or chimney.
- Valleys and junctions between adjoining roof slopes.
- Upstands and edges around flat-roof wall connections or roof openings.
Identify the detail and its surroundings
A grey metal surface in a photograph does not establish that the material is lead. The existing material, condition, method of attachment and adjoining roof or masonry should be identified before a repair is specified.
A concern at a junction may involve more than the visible metal. Ask which surrounding areas have been assessed and whether the proposal is a local repair, renewal of a particular detail or further investigation.

Useful information to share
- Identify the wall, chimney, valley or opening nearest the concern.
- Describe any internal staining and when it appears, without assuming the entry point.
- Mention previous sealant or flashing repairs if known. Use existing photographs or views available safely from the ground.
Agree the exact junction work
Ask the proposal to identify the material, extent of flashing or junction work, adjoining surfaces included and access arrangements. Any masonry work, roof-covering changes or treatment of concealed details should be stated separately.
The supplied photographs provide visual context for roof details. They do not establish a material specification or prove that a particular junction needs the same approach.
Questions about leadwork & flashing
Is every metal roof junction made from lead?
No. The material should be identified during assessment. Appearance in a photograph alone is not enough to specify lead or another metal.
Does a leak near a chimney mean the flashing needs replacing?
The location helps describe the issue but does not establish its cause. The flashing, surrounding roof and other relevant details need assessment before a scope is agreed.
