Our Leadwork and Flashing Process Explained

We take immense pride in our meticulous approach to every roofing project. Here is a step-by-step breakdown of how our expert tradespeople deliver reliable leadwork solutions:Thorough Inspection: We begin with a comprehensive assessment of your existing roof flashing. We frequently utilise our advanced drone roof surveys to safely and accurately identify hidden leaks, worn lead strips, or structural vulnerabilities.Material Selection: We exclusively use premium milled lead sheets, ranging from Code 3 to Code 8, ensuring complete compliance with rigorous BS EN 12588 standards.Expert Craftsmanship: Our directly employed roofers apply traditional lead bossing and lead welding techniques. This ensures the lead perfectly shapes to your roof tiles and brickwork without ever compromising its structural integrity.Final Watertight Checks: We conduct rigorous testing upon completion, verifying that all new step flashing, valley gutters, and aprons are fully secure against driving rain and severe weather.

Frequently Asked Questions About Roof Flashing

What are the signs my chimney flashing needs replacing?Common signs of failing flashing include damp patches appearing on your ceilings or chimney breast, visible cracks in the surrounding mortar, loose or missing lead strips on the roof, and heavy moss buildup around the chimney base. If you spot any of these issues, a prompt inspection is highly recommended to prevent further internal water damage.Why is lead used instead of modern silicone sealants?While sealants can provide a quick, temporary fix, lead is highly durable and naturally flexible. It shapes perfectly around complex roof structures and seamlessly accommodates thermal expansion, making it by far the most reliable material for long-term water ingress prevention.Do you provide emergency roof repairs in Tonbridge?Yes, absolutely.

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.
