Our Leadwork Process: From Inspection to Installation

Every successful lead roofing project begins with a thorough assessment. We take the time to understand the unique structural demands of your property before any work begins. Our straightforward process ensures you are fully informed at every stage, from the initial consultation to the final polish.During our visit, we assess the condition of your existing chimney flashing, step flashing, and valley gutters. If safe access is a challenge, we can utilise our advanced drone roof surveys to get a crystal-clear, close-up view of the damage without needing immediate scaffolding. Once we have identified the root cause of the problem, we provide a fully itemised quote detailing the exact work required.We only use premium milled and sandcast lead, carefully selecting the correct gauge for the specific job. From Code 3 lead for hidden soakers to heavy-duty Code 8 for robust flat roofs, we ensure every installation perfectly balances flexibility and durability. Our directly employed roofers then use highly skilled techniques to shape the metal seamlessly to your roof's contours.

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

The Long-Term Benefits of Professional Lead Roofing

Lead has been a staple in British construction for centuries, and for excellent reason. When installed by experienced professionals, it offers unmatched protection and performance. Choosing Kevington Roofing and Building LTD for your leadwork upgrades provides several distinct advantages for your property.Exceptional Longevity: When correctly detailed and installed, high-quality lead flashing can easily last for over a hundred years without needing replacement.Complete Weatherproofing: Lead expands and contracts naturally with seasonal temperature shifts, preventing the cracks and splits that commonly cause roof leaks.Moulds to Any Shape: Traditional lead bossing allows us to dress the material flawlessly around complex dormers, parapet walls, and uneven brickwork.Enhanced Kerb Appeal: Beautifully finished leadwork adds significant visual value, particularly on the traditional 1930s semis and period terraces common throughout Kent.Investing in quality materials and craftsmanship now means you avoid the stress and immense expense of emergency roof repairs and internal water damage further down the line.

How Do I Know If My Roof Flashing Has Failed?

Homeowners often ask us how to spot failing leadwork before it causes severe internal disruption. Understanding the early warning signs can save you significant time and money. Here are answers to some of the most common questions we receive regarding roof flashing and lead repairs.What are the signs of failing flashing? The most obvious signs are brown watermarks on your upstairs ceilings, damp patches spreading across chimney breasts, or visually slipped and warped lead on the roof exterior.What is step flashing? Step flashing is a method where individual, overlapping pieces of lead are layered and chased into the brickwork alongside a pitched roof, acting as a waterproof staircase that directs rainwater safely into your gutters.Can lead be repaired, or does it need replacing? Minor splits or thermal fractures can sometimes be expertly welded. However, if the lead has become excessively thin, brittle with age, or was originally installed using the wrong code, a complete replacement is the safest, most cost-effective long-term option.If you have any concerns about the health of your roof, it is always best to have it assessed by an expert before the damp spreads into your internal roof timbers.

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.
