Why Quality Chimney Flashings and Roof Valleys Matter

Lead is incredibly durable, flexible, and resistant to corrosion, making it the perfect material for weatherproofing the joints of your roof. It seals the gaps where your roof meets a vertical surface, such as brickwork or a chimney breast. When lead flashing degrades or pulls away, rainwater can quickly penetrate your loft space, causing damp, rot, and significant internal damage.We specialise in the installation and repair of all forms of leadwork. This includes chimney flashings, stepped flashing, lead valleys, and flat lead roof installations. By exclusively using high-grade materials like Code 4 lead for flashings and thicker grades for flat roofing, we ensure your roof joints can expand and contract safely with changing temperatures.Total weatherproofing: Stop leaks before they cause expensive structural damage.Long-lasting performance: Professionally installed leadwork can easily last for decades.Thermal efficiency: Properly sealed roof joints help prevent heat from escaping your home.Kerb appeal: Crisp, tidy leadwork adds a polished finish to any property.

Frequently Asked Questions About Lead Roof Repairs

What is Code 4 lead?Lead is graded by its thickness and weight, known as its code. Code 4 lead is the standard thickness used for chimney flashings, soakers, and stepped flashing. It is thick enough to resist tearing but flexible enough to be moulded around brickwork. Thicker codes, like Code 5 or 6, are typically used for flat roofs and wider roof valleys.What are the signs my chimney flashing needs repair?Look out for damp patches on your chimney breast inside the house, water stains on your upstairs ceilings, or visible gaps and lifting lead around the chimney stack itself. If you spot cracked mortar or slipped lead, call our emergency repair team before water ingress causes more internal damage.Is lead flashing better than modern alternatives?While modern GRP and EPDM flashing alternatives exist and have their uses, traditional lead remains the gold standard for complex junctions, period properties, and chimney flashings. Its unmatched lifespan, flexibility, and resistance to UV degradation make it a superb long-term investment.

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.
