01

Why lead flashing repair is vital for your roof

Lead is highly durable, but over time, exposure to the elements in Kent can cause it to crack, slump, or pull away from brickwork. Perished lead flashings are a leading cause of internal damp and water tracking. We specialise in replacing compromised lead with correctly fitted stepped flashings and aprons. By ensuring the lead is correctly cut and dressed into the mortar joints, we create a secure seal that stands up to heavy rain and wind, protecting your roof structure from long-term moisture damage.

02

Professional lead valley and chimney re-leading

Valleys and chimney stacks are the most vulnerable parts of any roof. If your lead valley is leaking or your chimney flashings are failing, it is important to act before internal ceiling damage occurs. Levi King offers tailored repair solutions, from installing robust Code 5 lead in high-flow valleys to complete chimney re-leading. We treat every job with precision, ensuring that the work is not only watertight but also structurally sound, using professional techniques that respect the original design of your home.

03

Heritage and conservation standards in West Kent

Many properties in Swanley and across Sevenoaks reside within conservation areas or feature historical building materials. When repairing or replacing leadwork, it is crucial to match the quality and installation method to the building's character. We understand the requirements for traditional code lead and lime-based mortar finishes, ensuring your repairs meet modern weatherproofing standards while remaining sensitive to your home's architectural history. We provide the expertise needed to navigate these technical requirements with confidence.

04

How do I know if my lead flashing has failed?

Common signs of failing lead include damp patches appearing on internal chimney breasts, peeling wallpaper, or visible cracking in the mortar holding the lead into the brickwork. Sometimes you may notice loose lead edges after high winds. If you are concerned about the state of your roofing, Levi provides honest, on-site diagnostic visits to assess the leadwork and the underlying timber battens. We pride ourselves on transparent communication, offering clear, written estimates for any necessary repairs or replacements without any high-pressure sales.

Leadwork & Flashing FAQs

Frequently Asked Questions About Roof Leadwork

Practical advice from Levi King on lead flashing repairs, stepped chimney aprons, and watertight valley renewals in Snodland and Aylesford.

Is your Snodland home leaking around the chimney or roof joints?

+

If you have spotted damp patches on your ceiling or walls, the leadwork is often the primary suspect. Lead flashing acts as the critical bridge between your roof tiles and the brickwork of your chimney or adjoining walls. In Snodland and across the Medway Valley, heavy rain can easily find its way behind failed or lifting flashings. Levi King provides a direct inspection to see if the metal has simply pulled away from the mortar or if the lead has reached the end of its natural lifespan.

How can I tell if my lead flashing needs a repair or a full replacement?

+

Lead is incredibly durable, but it eventually develops "fatigue" cracks after decades of expanding and contracting in the heat. If you can see visible splits or the metal looks paper-thin and brittle, a replacement is usually the only way to stop a leak for good. For minor issues, such as lead that has slipped out of its housing, Levi can often secure the existing sheet back into the brickwork using proper lead wedges. During an on-site survey, you will get a clear explanation of whether a localized repair or a new lead installation is the most practical fix.

Why is professional lead bossing important for my roof valleys?

+

Roof valleys carry a huge volume of water during a Kentish downpour. Lead bossing is the trade skill of shaping the metal around corners and gutter joins without thinning the material. If this isn't done correctly, the lead becomes a weak point where water pools and eventually seeps through to your roof timbers. Tonbridge & Malling Roofing installs heavy-duty lead valleys designed to channel water safely away from your home, using techniques that allow the metal to move naturally without cracking.

Do you handle chimney leadwork and repointing at the same time?

+

Yes. It is often the best approach to tackle these jobs together because lead flashings are tucked directly into the mortar joints of the chimney stack. If your mortar is perishing, water can track behind the lead and into your loft space. Levi King often carries out chimney leadwork alongside repointing and flaunching repairs. By fitting new Code 4 lead step flashings and refreshing the mortar in one visit, you create a complete weather-tight seal that saves you money on future scaffold costs.

What grade of lead does Levi King use for roofing repairs in Kent?

+

The thickness of lead is measured in "Codes." For most residential lead flashing repairs in Snodland, Levi uses Code 4 lead, which offers the right balance of weight and flexibility for chimney aprons and step flashings. For larger roof valleys or gutter linings where water flow is heavier, Code 5 is often used for its extra durability. Using the correct grade of rolled lead sheet ensures your roof remains watertight for decades rather than just a few years.
