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

Why Quality Lead Flashing Matters for Your Roof

Lead has been the premium material of choice for UK roofs for centuries, and for very good reason. Investing in professional leadwork provides several key advantages for your home:Unmatched Longevity: When installed correctly by seasoned professionals using the correct codes, milled lead can easily last for several decades, far outperforming many modern synthetic alternatives.Superior Waterproofing: Flashing acts as the primary seal at the most vulnerable parts of your roof. Proper chimney flashing prevents driving rain from penetrating the delicate gaps between brickwork and tiles.Thermal Flexibility: Lead naturally expands and contracts with the changing temperatures. This flexibility means it will not snap during freezing winters or warp in the summer heat.Kerb Appeal: Neatly dressed leadwork adds a traditional, high-quality finish to your roofline. This is particularly important for maintaining the character of older housing stock and properties situated in conservation areas.If you suspect your current flashing is compromised, do not wait for water damage to spread.

Common Questions About Leadwork and Roof Flashing

How do I know if my roof flashing needs replacing?The most common signs of failing flashing include damp patches appearing on your upstairs ceilings, water stains running down internal chimney breasts, or visible rust, cracks, and missing sections of lead on the roof itself. If you notice any of these warning signs, it is time to book a professional roof inspection immediately.What is the difference between lead welding and bossing?Both are traditional techniques used by skilled leadworkers to manipulate the metal. Bossing involves shaping a single piece of lead using special wooden mallets to perfectly fit a corner or junction. Lead welding involves melting two pieces of lead together to form a highly durable, watertight seam. We use both methods depending on the complexity of your chimney flashing or specific lead valley repair.Can I get an emergency roof repair for a leaking lead valley?Yes. A damaged lead valley can funnel significant amounts of water directly into your loft space, causing major disruption. We offer a fast response for emergency roof repairs across Northfleet, Gravesham, and Kent to secure your property and prevent further internal water damage.

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.
