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

Why Professional Roof Waterproofing Matters

Lead is incredibly durable, but it must be handled by experienced professionals. Poorly installed flashing is one of the most common causes of water ingress in Medway homes. By choosing our specialist lead bossing and welding services, you benefit from lasting protection.Properly installed lead valleys and step flashing can endure for decades, creating a highly effective barrier against heavy rain. By stopping damp and water ingress early, you protect your underlying roof timbers from rot and costly structural failure. Using the correct lead codes ensures your roof can handle thermal expansion during the heat of summer and freezing winter nights.

From historic building restorations in Rochester to modern roof maintenance in Gillingham, we ensure every project strictly adheres to UK building regulations.We use appropriate lead codes, such as Code 4 for standard flashing and Code 5 for valleys, guaranteeing compliance and longevity.

How do I know if my roof flashing needs replacing?

This is a common question from homeowners noticing potential roof trouble. Here are the key signs your leadwork may be failing:Are there damp patches on your ceilings?Water marks inside your home, particularly around chimney breasts or beneath roof valleys, are often the first sign that your flashing has degraded or pulled away from the masonry.Can you see cracked or missing lead?Extreme weather can cause older lead to split or slip out of place. If a visual inspection from the ground reveals gaps around your chimney base, it is time to book a drone roof survey.Is the mortar around the flashing crumbling?The mortar joints holding step flashing into the brickwork can deteriorate over time. If you notice crumbling pointing, rainwater can easily bypass the lead. We offer comprehensive repointing alongside our flashing repairs to solve this issue completely.

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.
