Slate Roofing in Kent

Welsh slate on Victorian and Edwardian houses needs a different eye to clay or concrete tile.

Slate Roofing in Kent

Slate roofs went onto a lot of Kent's Victorian and Edwardian housing, and most of them are still going today, decades after the nails holding the slates in place should have failed. That's the usual problem: the slate itself is often sound, but the nails have rusted through, so slates slip or slide out one by one.

We repair slate roofs slate by slate where that's enough, and re-slate fully when nail sickness is widespread. We work with reclaimed slate where matching old stock matters, or good quality new Welsh slate where that's the better option, always paired with correctly laid lead valleys and flashings.

Slate appears heavily on Victorian terraces and villas in towns like Cranbrook, Tunbridge Wells and parts of Ashford, as well as on individual period houses scattered through the Weald. Valleys, hips and chimney junctions on slate roofs are usually finished in lead, which ages differently to the slate around it.

Local knowledge

Common slate roof issues

01

Nail sickness

Rusted fixing nails let slates slip even though the slate itself is fine. Patching buys time, but widespread nail sickness points to re-slating.

02

Cracked or slipped slates

Impact damage or slipped slates are usually a straightforward repair if caught before water gets behind them.

03

Lead valleys on slate roofs

Valleys carry a lot of water on a slate roof. We check and renew lead here as part of most slate repairs.

From the trade

Common questions

Why do slates keep slipping even though they look fine?

It's usually the fixing nails that have failed, not the slate itself. That's a sign the roof may need re-slating rather than repeated patch repairs.

Can you source reclaimed slate to match an old roof?

Yes, reclaimed slate is often the right choice where matching the existing roof matters, particularly in conservation areas.

Do you replace the lead valleys when re-slating?

Normally, yes. It makes sense to renew lead valleys and flashings at the same time rather than reuse worn ones.
