Leadwork Services in London
Well-fitted leadwork helps keep vulnerable parts of a roof watertight, particularly around chimneys, valleys, dormers and roof junctions. When it splits, lifts or has been poorly installed, water can travel into the roof space and cause hidden damage. At RJC Roofing & Building, we provide professional lead roofing repairs and installation across London.
What Include
Our Leadwork Services in London
Lead Flashing Installation & Repairs
Lead flashing is used where the roof meets walls, chimneys and other raised sections. It creates a flexible weatherproof seal while allowing for normal movement in the building. We repair loose, cracked and badly fitted flashing, as well as replacing sections that are no longer providing reliable protection.
Lead Valleys & Roof Junctions
Valleys carry large amounts of rainwater between two roof slopes, so even a small defect can lead to serious leaks. We install and repair lead valleys, checking the surrounding tiles or slates, supporting structure and water flow at the same time.
Chimney Leadwork & Flashings
Chimneys are one of the most common places for roof leaks to develop. We repair and replace step flashing, cover flashing and leadwork around chimney stacks, taking care to create a secure seal without damaging the surrounding masonry or roof covering.

Professional Lead Roofing in London
Lead is a traditional roofing material, but it still needs to be installed with care. The size of each section, the number of fixings and the allowance for expansion all matter. If lead sheets are fitted in pieces that are too large or fixed too tightly, repeated temperature changes can cause splitting and movement.
Our leadwork services are suitable for pitched roofs, flat roof junctions, period properties, extensions, chimneys, dormers and commercial buildings. We can assist with isolated repairs, replacement sections and new lead detailing as part of a wider roofing project.
Before starting, we inspect the surrounding roof as well as the visible lead. A damp patch near a chimney, for example, may be caused by failed flashing, damaged pointing, cracked tiles or more than one issue at once. Looking at the whole area helps us recommend the right repair.
Why Choose RJC Roofing & Building for Leadwork?
London has a wide mix of roof styles, and many older homes still rely on traditional lead details that have been repaired several times over the years. On Victorian terraces in Islington or Hackney, access can be tight and the leadwork may sit alongside ageing slate. In areas such as Barnet, Ealing and Croydon, extensions and dormers often introduce several roof junctions that need careful waterproofing.
We take a practical approach to each job. Where a local repair is suitable, we’ll explain what can be done. Where the lead has split repeatedly, been incorrectly sized or reached the end of its useful life, replacement may be the more dependable option.
Customers value clear advice, tidy working methods and knowing that the less visible details have been handled properly. We focus on correct preparation, secure fixing and neat finishing rather than simply covering over an existing fault.

What is roof leadwork used for?
Leadwork is used to seal roof junctions and direct water away from vulnerable areas such as chimneys, valleys, walls, dormers and box gutters.
Can split lead flashing be repaired?
Sometimes. Small, isolated defects may be repairable, but repeated splitting can indicate that the lead was fitted incorrectly or has deteriorated more widely.
Why does leadwork crack?
Lead can crack due to age, poor fixing, sections being installed too large, restricted movement or repeated expansion and contraction.
How long does roof leadwork last?
Correctly installed lead can last for many years. Its lifespan depends on the quality of installation, exposure and whether the surrounding roof remains in good condition.
Do you replace chimney flashing?
Yes. We repair and replace lead flashing around chimney stacks, including step and cover flashing where required.
Can you repair lead valleys?
Yes. We assess the condition of the valley, the supporting structure and nearby tiles or slates before carrying out the appropriate repair or replacement.

Yes. We can install new lead details as part of new roof work, extensions, dormers and other roofing projects.
