How We Approach Your Leadwork and Flashing Installation

Every roof is unique, which is why we follow a meticulous, step-by-step process to ensure flawless leadwork. We begin with a comprehensive assessment of your property. For hard-to-reach areas, we utilise state-of-the-art drone roof surveys to safely and accurately identify compromised step flashing, cracked lead, or failing mortar without the immediate need for costly scaffolding.Once the issue is identified, we specify the correct grade of material for the job. We use high-quality milled and cast lead sheets ranging from Code 3 for lighter soakers, right up to Code 8 for heavy-duty flat lead roofing applications. This ensures the structural integrity and thermal movement of the material perfectly matches its intended use on your roof.Our skilled tradesmen then employ traditional lead bossing and lead welding techniques to shape the metal perfectly around chimneys, dormer windows, and roof valleys. This craftsmanship creates a seamless, impenetrable barrier against rainwater. Finally, we treat the new leadwork with patination oil to prevent unsightly white carbonate stains from washing down your roof tiles, leaving a clean, professional finish.

Why Quality Lead Flashing Protects Your Home

Investing in professional leadwork provides long-term security for your property.

By choosing expert lead installation, you are actively preventing costly emergency roof repairs further down the line.Unmatched Longevity: When expertly installed, high-quality lead flashing can last well over 100 years, significantly outperforming synthetic alternatives.Superior Waterproofing: Custom lead bossing allows the metal to be shaped seamlessly around awkward angles, providing a completely watertight seal around chimneys and roofline junctions.Flexibility: Lead naturally adapts to the thermal expansion and contraction of your roof throughout the changing seasons, preventing cracking and splitting.Kerb Appeal: Neat, professionally dressed leadwork adds a traditional, high-quality finish to your home, particularly important for preserving the character of older properties in Kent.By securing your roof's weakest points with premium materials, you improve your home's overall thermal efficiency and weather resistance.

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.
