Why Quality Roof Flashing Matters for Your Property

Roof flashing plays a crucial role in directing rainwater away from the vulnerable joints of your building. Without professionally installed step flashing, lead valleys, or chimney flashings, rainwater can easily seep beneath your roof tiles. Over time, this hidden moisture leads to rotting roof timbers, damaged insulation, and expensive internal ceiling repairs.By investing in professional roof leak prevention, you are actively preserving the structural integrity of your home. Lead is an incredibly durable, malleable material that expands and contracts naturally with temperature changes. When handled by experienced Surrey roofing specialists, a well-installed lead flashing system will outlast many other roofing materials.Long-lasting durability: High-quality lead withstands extreme weather without cracking or splitting.Seamless protection: Precision lead welding ensures a watertight seal at complex roof junctions.Kerb appeal: Neatly dressed leadwork enhances the visual appeal of both modern homes and period properties.Ready to secure your roof against the elements?

Is Your Chimney or Valley Flashing Failing?

Many homeowners only realise their flashing has deteriorated when water starts dripping through the ceiling. However, catching the early warning signs can save you from requiring extensive structural repairs. Flashing is most commonly found around chimneys, roof valleys, skylights, and adjoining walls.Look out for lead that has visibly slipped, lifted out of the brickwork mortar, or cracked due to age and thermal movement. You might also spot damp patches on your upstairs ceilings or chimney breast, which is a clear indicator that water ingress protection has been compromised.If you spot any of these signs, particularly after heavy winds or winter storms, immediate action is required. We offer rapid lead flashing repairs to make your home safe and prevent further internal damage. Do not attempt to climb onto the roof yourself; leave it to our fully insured experts.

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.
