How Do I Know If My Roof Flashing Needs Repair?

Roof flashing forms the vital protective seal around chimneys, skylights, dormer windows, and roof valleys. Over time, thermal expansion, harsh weather, and general wear can cause these seals to degrade. If you notice damp patches on your upstairs ceilings, water running down a chimney breast, or visible cracks in the roofline joints, it is time to call in the professionals.Ignoring failing leadwork frequently leads to severe structural decay and costly interior water damage. Our skilled roofers are adept at identifying these vulnerabilities before they escalate. We can conduct a thorough manual assessment or a state-of-the-art drone roof survey to safely inspect hard-to-reach areas on your Southborough home. Catching these weatherproofing issues early ensures your property remains safe, warm, and entirely dry.Related services: Roof Leak Detection | Drone Roof Surveys

Frequently Asked Questions About Roof Leadwork

How long does lead roof flashing last?When installed correctly to BS 6915 standards using the appropriate code of lead, high-quality leadwork can easily last over 60 years. It is incredibly resistant to corrosion, severe weather, and UV degradation.Can you repair split lead flashing instead of replacing it?In many cases, minor splits or cracks can be repaired using specialist lead welding services. However, if the lead has significantly thinned or degraded due to age, a full lead valley replacement or new chimney flashing is often the most cost-effective, long-term solution.Do you offer drone roof surveys for leadwork inspections?Yes. If your roof has complex or hard-to-reach joints, we offer professional drone roof surveys. This allows us to safely and accurately assess the condition of your leadwork and flashings without the immediate need for costly scaffolding.

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.
