Our Lead Flashing Repair and Installation Process

Our Lead Flashing Repair and Installation Process A leaking roof often stems from failed flashing rather than broken tiles. To ensure a permanent fix, we follow a rigorous and detailed process for every leadwork project we undertake in Loughton. Structural Assessment: We begin with a thorough inspection of your roof, checking the existing lead valleys, chimney aprons, and step flashing for signs of fatigue, splitting, or mortar degradation. Material Selection: We strictly use premium milled and sand-cast lead that complies with BS EN 12588 standards. Depending on the application, we select the correct thickness—typically Code 4 for standard flashings and Code 5 for wider gutters and valleys. Precision Cutting and Bossing: Our skilled tradesmen expertly cut, shape, and boss the lead. This traditional technique ensures the metal sits perfectly against your brickwork and tiles without compromising its natural ability to expand and contract. Weatherproofing: Finally, we point the lead securely into the brickwork using high-quality mortar or specialist lead sealant, creating an impenetrable barrier against rainwater.

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

Why Choose Traditional Lead Roofing for Your Property?

Why Choose Traditional Lead Roofing for Your Property? Lead remains one of the most reliable materials in the UK construction trade. While modern alternatives exist, traditional leadwork offers unparalleled benefits for homeowners looking to secure their properties long-term. Maximum Durability: When installed correctly by our seasoned professionals, high-quality lead flashing can provide over 60 years of unwavering protection. It is highly resistant to atmospheric corrosion and temperature fluctuations. Exceptional Flexibility: Lead naturally expands and contracts with changing temperatures. This flexibility prevents cracking, making it the ideal material for sealing awkward joints around chimneys, dormer windows, and adjoining walls. Sustainable and Eco-Friendly: Lead is a 100% recyclable material. Choosing traditional leadwork is an environmentally responsible decision that reduces waste while adding genuine kerb appeal and value to your home. Need immediate assistance with a leaking roof?

Common Questions About Roof Flashing and Leadwork

Common Questions About Roof Flashing and Leadwork What are the first signs my roof flashing has failed? The most common indicator of failed flashing is a damp patch appearing on your ceiling or walls, particularly near a chimney breast or where an extension meets the main house. You might also spot slipped mortar, lifting lead strips, or visible water ingress in your loft space during heavy rain. What is the difference between Code 4 and Code 5 lead? Lead is graded by its thickness and weight. Code 4 lead is slightly thinner and is typically used for standard flashings, such as step flashing and cover flashings. Code 5 lead is thicker and more robust, making it the perfect choice for areas that handle a larger volume of flowing water, such as lead valleys and flat roofing details. How much does lead flashing replacement cost? The cost varies depending on the amount of lead required, the complexity of the bossing, and the height of the roof. We provide free, transparent surveys to assess your specific needs and deliver an itemised quote without any obligation. Contact us on 01689 663319 to arrange your survey.

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.
