Protecting Your Property with Precision Leadwork

Lead is one of the most durable and reliable roofing materials available, often outlasting the tiles or slates surrounding it. However, over time, thermal expansion, harsh weather, or poor initial installation can cause lead flashing to crack, slip, or deteriorate. This is a common cause of unexpected water ingress in Grays homes.Our specialist leadwork services cover everything from precision lead welding to the complete renewal of lead valleys and chimney flashings. We use the correct codes of lead sheet, such as Code 4 for standard flashings and Code 5 for wider valleys, ensuring maximum longevity and flexibility. By addressing split or degraded lead early, we help you avoid costly internal damp issues and extensive roof maintenance down the line.

While mastic sealants might offer a temporary fix for a small leak, they degrade quickly under UV light and weather exposure. Professional lead welding provides a permanent, watertight, and structurally sound solution for step flashing and lead valleys.How much does lead flashing replacement cost in Grays?The cost varies depending on the amount of lead required, the complexity of the roof shape, and any scaffolding requirements.

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.
