Natural Welsh slate was the premium roofing material across Maidstone's Victorian and Edwardian building boom. The large period houses on Tonbridge Road, London Road and the conservation area streets, and the Victorian villas in Bearsted and West Malling, were originally roofed in Penrhyn or Ffestiniog Welsh slate. A well-laid slate roof can last 80–150 years — but nail failure (nail sickness) is the dominant failure mode on Maidstone's Victorian stock, and when it occurs it affects the whole roof rather than isolated tiles.
Single slate replacement is straightforward where matching material is available. We hold reclaimed Welsh slate stock in the most common Maidstone sizes — 20x10, 22x12 and 24x14 — and can source Spanish slate for less critical applications. Two copper nails per slate is non-negotiable on all repair work.
Where nail sickness is widespread or sarking felt has failed, a full re-roof is the correct solution. We strip to bare rafters, inspect all timbers, lay breathable membrane, rebatten and re-slate using graded Welsh or Spanish natural slate. 10-year workmanship guarantee. Welsh slate sourced specifically for conservation area properties.
Maidstone town centre conservation area and several village conservation zones specify natural slate as the required material. We're familiar with Maidstone Borough Council requirements and can support planning applications where material specification is needed.
Typical cost: £200 – £18,000 — Slate repairs from £200. Full Welsh slate re-roof typically £8,000–£18,000 depending on size.
We survey the slate at your Maidstone property, checking nail condition and slate integrity to distinguish nail sickness from slate failure.
We source matching new or reclaimed Welsh slate, present samples, and provide an itemised written quote.
We re-nail with copper nails or strip and re-lay as specified, renewing lead work at valleys and abutments.
The finished roof is inspected, photographed and covered by our written workmanship guarantee. Call 0162 229 6232.
A survey settles it. Nail sickness is only assessable from inside the roof space. Our roof inspection fee is credited in full against any work you subsequently book.

In most cases yes. We hold reclaimed Penrhyn and Ffestiniog Welsh slate in common Maidstone sizes. An exact colour match is not always possible with reclaimed material but we select the closest and discuss options before ordering.
Nail sickness occurs when original iron fixing nails corrode — slates then rely only on the nib to stay in place and begin slipping randomly. On Maidstone's Victorian properties, widespread nail sickness typically becomes apparent from the 80–100 year mark. Multiple slipped slates in different areas and rattling in wind are the main signs.
For properties within the Maidstone town centre conservation area, natural slate is typically required like-for-like. Fibre cement or concrete substitutes usually need planning consent. We advise before quoting.
A Victorian semi takes 4–6 days. Larger properties with complex hips or dormers typically 6–10 days. Scaffolding erection adds half a day at the start.
Often yes. Welsh slate itself lasts over a century; it is usually the nails that fail. Selective re-nailing with copper nails can add 20 to 30 years.
Yes. We supply new Welsh slate and source reclaimed slate where a closer match to weathered originals is needed, and we present samples before ordering.
