How Our Traditional Leadwork Process Works

Leadwork is a highly skilled trade that requires precision and a deep understanding of how materials expand and contract. Our approach ensures every roof valley, box gutter, and chimney is properly sealed.1. Comprehensive Assessment: We begin with a thorough inspection, often utilising our drone roof survey technology, to safely assess the condition of your existing lead flashing and identify any hidden vulnerabilities.2. Transparent Quotation: You receive an itemised, jargon-free quote. We explain exactly what needs doing, whether it is a minor patch repair or a full lead replacement, with no hidden costs.3. Precision Installation: Our tradesmen use traditional lead bossing and welding techniques, shaping the lead perfectly to your roof's contours. We use the correct code of lead for each specific application to ensure maximum durability.4. Final Quality Check: Every project is rigorously checked to guarantee it meets our exacting standards and leaves your property completely secure against the elements.

Frequently Asked Questions About Leadwork

What is the difference between milled lead and sandcast lead?Milled lead is machine-rolled for a uniform thickness, making it ideal for standard flashing and modern roofs. Sandcast lead is made using traditional methods, creating a slightly textured finish that is often required for listed buildings or properties in conservation areas.How do I know if my chimney flashing needs repairing?Common signs include damp patches on your chimney breast, water stains on your ceilings, or visible cracks, lifting, and deterioration around the base of the chimney stack externally. If you notice any of these, we recommend booking a roof inspection immediately.Can lead flashing be repaired or must it be replaced?Minor splits can sometimes be resolved with expert lead welding. However, if the lead is severely degraded, thin, or poorly installed originally, a full lead flashing replacement is the safest and most cost-effective long-term solution.

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.
