01

Why lead integrity matters for your roof

Lead flashings, valleys, and chimney aprons are designed to allow for the natural movement of a building without breaking the seal. Over time, factors like thermal expansion, heavy wind-driven rain across the North Downs, and natural material fatigue can cause lead to crack, slip, or lift. When this happens, water tracking becomes inevitable, often leading to damp patches on internal chimney breasts or ceiling stains in upstairs rooms. Levi King specialises in identifying these points of failure before they cause significant structural or decorative damage to your home.

02

Professional installation of Code 4 and Code 5 lead

For all leadwork repairs and installations in Northfleet, we work strictly with high-quality rolled lead sheet to ensure long-term durability. We typically utilise Code 4 lead for standard step flashings and aprons, while heavier Code 5 lead is reserved for valleys and gutter linings where extra thickness and resistance are required. Every joint is carefully dressed and secured, allowing the metal to expand and contract with the changing temperatures of the Kentish seasons without compromising the weatherproofing of your roof.

03

Addressing chimney leadwork and valley leaks

Chimneys are high-risk areas for leaks, especially where the brickwork meets the tile surface. If your chimney flaunching is cracking or your lead flashings have pulled away from the masonry, it creates a direct channel for water to enter your loft space. Levi also repairs and replaces failed lead valleys, which are prone to debris buildup and trapped moisture. By restoring these junctions with traditional leadwork methods, we ensure your chimney stack and valley lines are fully protected against the weather-beating typical of the Gravesham area.

04

How do I know if my lead flashing needs repair?

Many homeowners only realise there is an issue with their leadwork when they spot a damp stain appearing after heavy rain. Externally, you might see gaps where the lead has pulled away from the brickwork, or find loose, torn edges around a chimney stack. If you notice signs of water ingress or suspect your roof is failing at its joints, it is better to have it inspected sooner rather than later. Levi King provides direct, on-site diagnostic visits to assess the condition of your leadwork and recommend the most effective, honest repair solution.

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.
