01

Addressing Nail Sickness and Slipped Slates

One of the most frequent challenges we see with older roofs is nail sickness, where the original metal fixings corrode over time, causing slates to loosen or slip. If you notice gaps in your roof line or find fragments of slate in your garden, it is vital to act before water ingress occurs. We specialise in replacing damaged or missing slates, using matching materials to blend with your existing roof surface. By addressing these smaller issues early, we help prevent more significant damage to your timber battens and interior ceilings.

02

Professional Leadwork and Chimney Maintenance

A roof is only as strong as its weakest point, which is often where the slate meets the chimney stack or valley. We provide expert lead flashing repair and chimney repointing to keep water from tracking behind your brickwork. Whether your property requires a new Code 4 lead apron or a repair to your existing stepped flashings, we ensure that the weathering is installed correctly to manage rainwater runoff effectively, particularly during the heavier rainfall typical of the North Downs area.

03

Managing Heritage Roofs in Conservation Areas

Swanley and Sevenoaks are home to many period properties where planning and conservation controls are strict. When working on these buildings, we prioritise the use of high-quality materials that meet local authority expectations. We take the time to inspect your roof properly, ensuring that any replacement slates or leadwork align with the heritage of your home. Our goal is to provide a durable repair that respects the original architecture while meeting modern standards for safety and weather resistance.

04

Slate Roofing Guidance

Frequently Asked Slate Repair Questions

Straightforward trade advice from Levi King on diagnosing slipped slates, repairing nail sickness, and restoring natural slate roofs in Snodland, Tonbridge & Malling, and Aylesford.

Why are slates falling off my roof and into the garden?

+

This is usually caused by nail sickness. On many older Snodland houses, the nails holding the slates have rusted away. Once the nail fails, the slate slides down the roof. It can also be caused by timber battens rotting or high winds catching a loose slate. Levi King can inspect your roof to see if it’s a one-off repair or a sign that the roof needs more attention.

Can you match the existing slates on my Snodland property?

+

Yes. Whether you have natural Welsh slate, Spanish slate, or even reclaimed Kent peg tiles, Levi sources materials that match your existing roof in terms of colour and profile. This is particularly important for heritage properties and homes in conservation areas around Tonbridge and Malling.

Do I need a full re-roof if I have a few slipped slates?

+

Not necessarily. If the rest of the slates and the underlying felt are in good condition, a localised repair is often enough. However, if the slates are falling because the nails have all corroded (nail sickness), a repair might only be a temporary fix. Levi King provides an honest appraisal, telling you exactly what is needed to keep the roof watertight without recommending unnecessary work.

How quickly can you attend a roof leak in Snodland?

+

Being based in Ditton, Levi King can usually respond very quickly to emergency calls in Snodland and the ME6 area. For active leaks, the priority is always to get the property "made safe" with tarpaulins to prevent internal water damage before carrying out the permanent slate repair.

Is my chimney causing the leak on my slate roof?

+

It is quite common. Water often tracks down the side of a chimney if the lead flashing has cracked or the mortar pointing has perished. Levi inspects the leadwork and the chimney flaunching alongside the slates to find the exact entry point of the water.

How much does it cost to fix a slate roof in Snodland?

+

Every roof is different depending on the height, the type of slate used, and the ease of access. Levi King provides free, transparent written quotations after a site visit. Because he is a sole trader, you aren't paying for large office overheads or sales commissions.
