Frequently Asked Questions About Roof Flashing

What are the main signs my lead flashing needs replacing?Look out for visible cracks, splits, or gaps in the leadwork around your chimney, skylights, or roof valleys. Internally, damp patches on upstairs ceilings or water marks on chimney breasts are strong indicators of water ingress caused by failing flashing.Why is my leadwork splitting?Splitting usually occurs when the flashing was installed using pieces of lead that are too large, or when the incorrect lead code was used. This prevents the metal from expanding and contracting naturally with seasonal temperature changes. Our expert roofers always use the correct sizing and codes to prevent this specific failure.Do you offer emergency call-outs for leaking roofs?Yes. If your flashing has blown off during a storm or you have discovered a sudden severe leak, we provide an emergency roof repair service across Sevenoaks and Kent to secure your property quickly and stop further internal damage.

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.
