Why Precise Lead Flashing is Crucial for Your Roof

Lead flashing acts as the primary defence against water ingress in the most vulnerable areas of your roof. This includes the joints where your roof meets a brick wall, around chimney stacks, and within the dips of lead valleys. If these areas are poorly installed or deteriorate over time, water will easily find its way into your home, causing costly damp and structural issues.As experienced Medway roofers, we strictly adhere to BS EN 12588 standards. This ensures that the lead we use is of the correct code and thickness, providing the durability and flexibility required to withstand natural thermal expansion and contraction. From intricate step flashing to robust dormer coverage, our precise roof waterproofing methods keep your home safe, dry, and structurally sound all year round.

Our installation techniques allow for this movement, preventing the material from cracking or splitting over time.Enhanced Kerb Appeal: Neatly dressed leadwork adds a clean, traditional finish that complements both historic building restorations and modern roof maintenance projects.Prevention of Internal Damage: By securing vulnerable joints and valleys, you eliminate the risk of internal damp, protecting your ceilings, insulation, and roof timbers.

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.
