How Our Leadwork and Flashing Process Works

Every successful lead roofing project starts with a detailed assessment. We take a careful, methodical approach to ensure your property remains perfectly sealed against the unpredictable UK weather.Thorough Inspection: We start by examining your existing flashings, valleys, and gutters to identify the root cause of any water ingress. For hard-to-reach areas, we often utilise our drone roof survey technology to get a clear picture safely.Bespoke Preparation: We use high-quality milled lead, selecting the correct code for the specific job, whether that is Code 4 for standard chimney flashing or thicker Code 5 and 6 for lead gutters and flat roofs.Precision Installation: Our skilled team uses traditional lead burning and bossing techniques. This shapes the lead perfectly to the contours of your roofline, ensuring seamless protection without compromising the material thickness.Final Testing and Cleanup: Once the new lead is dressed and secured, we thoroughly check all seals and clear away any debris, leaving your property spotless.

Why Choose Kevington Roofing for Leadwork & Flashing in Swanley & Sevenoaks?

Why High-Quality Lead Roofing Matters for Your Property

Lead has been trusted in British construction for centuries, and for good reason. When installed by experienced professionals, it offers unmatched benefits for your home or commercial building.Unrivalled Longevity: High-quality traditional leadwork can easily last for decades. It outlasts many modern alternatives, making it a highly cost-effective investment over its lifespan.Superior Weatherproofing: Because lead is highly malleable, it expands and contracts naturally with temperature changes. This prevents cracking and ensures a continuous, watertight barrier around vulnerable joints like chimneys, parapet walls, and roof valleys.Heritage Aesthetic: For period properties in the City of London, authentic leadwork maintains the building historical character and kerb appeal, which is often required for older housing stock.Eco-Friendly: Lead is one of the most recycled materials in the construction industry, making it a surprisingly sustainable choice for environmentally conscious property owners.

Common Questions About Leadwork and Flashing

How do I know if my roof flashing needs replacing?The most common signs of failing flashing are damp patches on your ceilings or walls, particularly around chimney breasts or directly under roof valleys. If you can see the lead peeling away, curling, or cracking from ground level, it is time to call in an expert.What is the difference between lead bossing and lead burning?Lead bossing involves physically beating and stretching the lead into shape using specialist wooden mallets. Lead burning is a traditional welding technique that melts two pieces of lead together to form a permanent, watertight bond. We use both methods depending on the complexity of your roof structure.Can you repair leadwork instead of replacing it entirely?In many cases, yes. If the underlying lead is still in good condition but a small section has split or lifted, we can carefully clean the area and perform a lead burn repair to seal it. However, if the lead is severely thinned or suffering from widespread fatigue, a full replacement is the safest, most cost-effective long-term option.

Leadwork & Flashing FAQs

Frequently Asked Questions

Answers to common questions about our specialist leadwork, chimney flashing, and roof repair services from the experts at Kevington Roofing and Building LTD across Swanley, Sevenoaks, Kent, and Croydon & South London.

How do I know if my chimney flashing needs repairing?

+

The most common sign is water staining on the ceiling or walls around your chimney breast. You might also see visible gaps where the metal has pulled away from the brickwork, or find small pieces of mortar on the ground that have fallen from the flashing joints. If you are unsure, we can perform a quick drone survey to check the condition safely.

Can’t I just use bitumen tape to fix a leaking lead valley?

+

Flash-band or bitumen tapes are only temporary patches. They struggle with the expansion and contraction of the roof and usually fail within a few months. For a permanent fix in the Swanley area, we always recommend replacing the failed section with new, correctly weighted lead that is properly bossed and fixed.

How long does it take to replace lead flashing on a standard house?

+

Most flashing repairs, such as around a single chimney stack or a porch, can be completed within a single day. Larger projects, like replacing long lead valleys or installing a lead flat roof, may take two to three days. We always aim to keep your home watertight throughout the entire process.

Is lead theft a problem in Kent and how can you prevent it?

+

While lead theft can happen, we can use specific fixing methods and high-quality adhesives to make it much harder to remove. For high-risk areas, we can also discuss modern "lead-alternative" products that have no scrap value but offer similar waterproofing performance, though traditional lead remains the gold standard for longevity.
