Protecting Your Home from Water Ingress

The Importance of High-Quality Roof FlashingRoof flashing is the crucial weatherproofing system that seals the vulnerable joints of your roof. Wherever your roof meets a vertical surface—such as a chimney, dormer window, or adjoining wall—lead flashing acts as a robust barrier against rainwater. When flashing degrades, splits, or slips, it provides a direct path for water to enter your property, leading to damp patches, damaged ceilings, and severe structural decay over time.At Kevington Roofing and Building LTD, we specialise in identifying and resolving these vulnerabilities. We frequently handle step flashing for traditional Victorian terraces, lead aprons for modern extensions, and complex lead valley repairs where two pitched roofs meet. By addressing these weak points proactively, we save homeowners from the costly internal damage caused by hidden leaks.

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

Our Leadwork and Flashing Process

How We Deliver Precision Lead InstallationsEvery successful leadwork project relies on meticulous preparation and expert execution. Our transparent, step-by-step process ensures your roof remains watertight for decades to come.1. Detailed Structural AssessmentWe begin with a thorough inspection of your existing roof structure. Using advanced drone roof surveys where necessary, we identify the exact source of water ingress and assess the condition of your surrounding tiles and mortar.2. Specification and Precision CuttingWe supply only premium-grade materials, carefully selecting the appropriate thickness for the job. We typically use Code 4 lead for standard flashings and soakers, while heavier Code 5 or Code 6 lead is chosen for valleys, gutters, and flat roofing sections. Every piece is precision-cut to fit the unique contours of your property.3. Expert Bossing and WeldingOur skilled craftsmen use traditional bossing and specialist lead welding techniques to shape the metal seamlessly around corners and masonry. This allows the lead to expand and contract naturally with temperature changes, preventing future thermal cracking.4. Weatherproofing and PointingFinally, the new leadwork is securely chased into the brickwork and pointed using high-quality mortar or specialist lead sealants, guaranteeing a completely watertight and aesthetically pleasing finish.

Benefits of Traditional Lead Roofing

Why Invest in Premium Lead Replacements?Lead has been trusted in British construction for centuries, and for good reason. When installed by experienced lead roofing specialists, it offers unparalleled benefits for your property.Exceptional Longevity: High-quality lead flashing can easily outlast the roof tiles themselves, often providing upwards of 60 to 100 years of reliable protection.Complete Weather Resistance: Unlike plastic or felt alternatives, lead does not degrade under prolonged UV exposure and can withstand the harshest winter storms.Flexibility and Custom Fit: Lead is highly malleable, allowing our technicians to dress it perfectly around complex architectural features, chimneys, and roof junctions.100% Sustainable: Lead is one of the most environmentally friendly roofing materials available, being fully recyclable at the end of its exceptionally long lifespan.Investing in correct roof weatherproofing initially prevents the need for constant patchwork repairs, adding both security and kerb appeal to your home.

Frequently Asked Questions About Roof Flashing

Common Questions from Chigwell HomeownersWhat are the main signs my chimney flashing is failing?Look out for damp patches on your ceiling or chimney breast, water stains running down interior walls, or visible daylight in your loft space. Externally, cracked mortar, lifted lead, or missing step flashing are clear indicators that an emergency repair is required.Should I repair or replace my lead flashing?If the lead is relatively new but has lifted due to mortar failure, a simple re-pointing service may suffice. However, if the lead has thinned, cracked, or degraded due to thermal expansion, a full replacement using fresh Code 4 or Code 5 lead is the most cost-effective and secure solution.How much does new lead flashing cost?The lead flashing cost varies depending on the complexity of the roof junction, the thickness of the lead required, and the amount of scaffolding needed for safe access. We always provide free, itemised quotes so you have a clear, accurate price upfront.

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.
