Why is secure chimney flashing so important?

The areas where your roof meets brickwork, such as around chimney stacks, dormer windows, and adjoining walls, are naturally vulnerable to water ingress. Roof flashing acts as a vital waterproof seal bridging these gaps. If your flashing is cracked, poorly installed, or lifting, rainwater can quickly seep into your roof space, causing damp, timber rot, and expensive internal damage.Traditional lead is the gold standard for these joints because it can expand and contract with changing temperatures without tearing. However, age and thermal movement can eventually cause lead to split or slip out of the mortar joints. Common signs that you need roof repairs in Basildon include damp patches on your ceilings, visible daylight around your chimney breast in the loft, or pieces of lead hanging loose after high winds.We use advanced drone roof surveys to safely and accurately inspect your roof flashing. This allows us to spot failing leadwork early, preventing minor leaks from turning into major structural problems.

Frequently asked questions about leadwork

How long does lead flashing usually last? High-quality lead flashing, when installed by skilled professionals using the correct thickness (Code 4 or 5), can last anywhere from 50 to 100 years. Its longevity depends on correct installation that accommodates thermal movement.Can you repair an existing lead valley, or does it need replacing? Minor splits can sometimes be repaired using traditional lead welding techniques. However, if the lead has significantly thinned or suffered extensive thermal fatigue, a complete lead valley repair or replacement is often the most cost-effective, long-term solution.What is lead bossing? Bossing is a highly skilled, traditional roofing technique where a single sheet of lead is stretched and shaped using specialized wooden tools to fit neatly around corners and roof penetrations without the need for cutting or welding.Protect your property from water ingress today.

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.
