Natural slate is the covering on Ashford's older and period properties. Slate roofs last a century, so their faults are almost always localised and repairable rather than terminal.
When it is not the answer: A sound slate roof with a few slipped slates does not need replacing - replacing a century-lifespan slate roof for a localised fault is an expensive mistake. Read the full guide.
Ashford's Victorian and Edwardian housing stock in Newtown, Kennington and the older residential streets carries Welsh slate on a significant proportion of its front elevations. Original Welsh slate from the late 19th century is still in service on many of these properties — 100-130 years old and still providing effective weatherproofing. When individual slates fail on these roofs, the correct repair material is reclaimed Welsh slate that matches the original in colour, thickness and surface texture. Concrete tile patches and Spanish slate repairs on period Ashford properties are visible from the street and devalue the property's appearance as well as its planning compliance in conservation-adjacent areas.
Spanish slate became the dominant 'natural slate' in the UK market from the 1980s onwards due to its lower cost. We install it when clients specifically require it and budget is the primary driver. However, we always advise on the comparative lifecycle costs: a Welsh slate roof re-done correctly lasts 80-100+ years. A Spanish slate roof typically lasts 25-35 years before the delamination and nail corrosion failures begin. For a period property where the slate will be visible and the building will be owned for decades, Welsh slate is the correct specification.
We source reclaimed Welsh slate from specialist Kent and South East suppliers for repair work on Ashford's period housing. Reclaimed slate from the same quarry era as the original roof provides the best colour match and surface character. New Welsh slate from active quarries (principally Penrhyn and Dinorwig) is available for re-roofing work and provides the same performance characteristics with a uniform appearance.
We assess the slate condition, batten and underlay state, and advise on repair vs re-roof before quoting.

Slate work runs year-round; only high wind or ice at height causes rescheduling.
Localised slate repairs run from ladders or a tower; patch re-slating and full re-slates need scaffold. Scaffold is specified for: patch re-slating, valley work, or any full re-slate - always itemised in your written quote, never a hidden extra, and we arrange it.
Ashford's Victorian terraces around Newtown and Church Road often have rear access only, so scaffold and skip placement need planning; the post-war estates at Bockhanger and Stanhope have driveways that usually take a skip without a permit. Pavement scaffold and skip permits go through Ashford Borough Council; allow a few working days on streets like the terraces around Newtown, Bank Street, the older lanes off Beaver Road where space is tight.
Dense, non-laminar structure. Does not absorb moisture significantly. Freeze-thaw resistant. Original Victorian Welsh slate still in service on Ashford properties 130 years later.
Laminar structure delaminating under freeze-thaw cycling. Higher absorption. Surface delamination typically begins at 20-25 years on Kent properties. Lower initial cost, higher lifecycle cost.
The correct material for Victorian and Edwardian Ashford properties. Reclaimed slate matches the original in colour and texture. Conservation area compliant.
Welsh slate costs more upfront. Over 100 years, one Welsh slate roof vs three Spanish slate roofs — the lifecycle cost comparison is not as different as the initial quote suggests.
"Victorian terrace with Welsh slate front elevation. Three slates had slipped and a previous repair had used concrete tile as a patch. They sourced reclaimed Welsh slate for a proper match and removed the concrete tile repair. Now looks as it should."
"Full Welsh slate re-roof on our Edwardian detached. They sourced the slate from a specialist, the batten work was done correctly and the finished roof is exactly right for the property. Expensive but worth every penny."
"Loose slate on the back pitch clipped and re-fixed. Quick assessment, correct solution, fair price. Didn't try to sell me a re-roof I didn't need."
Natural slate for roofing is available from two primary sources in the UK market: Welsh slate (quarried in Gwynedd and Pembrokeshire) and Spanish slate (imported from Galicia, northwest Spain). Both are natural stone products, but their performance characteristics are substantially different.
Welsh slate is a fine-grained metamorphic rock with a consistent grain structure that produces thin, dense slates resistant to water absorption and frost damage. The Penrhyn quarry in Gwynedd has been producing roofing slate continuously since the 16th century — the earliest slates from this quarry are still performing on buildings they were installed on in the 1700s. Service life for correctly installed Welsh slate on a standard pitch is 80–150+ years. Welsh slate is significantly more expensive than Spanish slate — typically 3–4 times the material cost — but the lifecycle cost comparison over 100 years strongly favours Welsh slate.
Spanish slate is a softer, more laminar rock. The laminar structure means the slate is more prone to delamination under freeze-thaw cycling — water absorbed into the laminar planes expands on freezing, progressively separating the slate layers. Delamination failure on Spanish slate typically begins at 25–35 years and accelerates thereafter. On a property where the slate will be in place for 50+ years, Spanish slate requires a mid-life replacement that Welsh slate does not. For a short-term property holding or a tight budget, Spanish slate is a legitimate choice. For a long-term owner, Welsh slate is the better investment.
Ashford's Victorian and Edwardian properties that carry original Welsh slate roofs present a sourcing challenge when repairs are needed: the original slate is typically 120–140 years old, well-weathered to a blue-grey surface, and not closely matched by new Welsh slate from current production. For small repairs (up to 20 slates), we source reclaimed Welsh slate from Kent and Sussex demolition sources. Reclaimed slate typically provides a closer colour and surface match than new slate, is pre-weathered to blend with the original, and is the correct specification for conservation area properties.

Slate repairs and re-slating carry our written 10-year workmanship guarantee; natural slate itself has a century-plus lifespan.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Slate repairs are quiet and localised; a full re-slate is a larger job with scaffold, but you stay in the house and we protect the property throughout. For exterior jobs there is no need to be in; we only need agreed access and, for some jobs, an outdoor power point.
Slate can be worked in most conditions; we avoid ice and high wind at height. The Stour valley sits low and damp, a frost pocket that slows drying through autumn and winter, so we build a weather margin into every Ashford booking.
Slate repairs produce a little slate dust and the odd offcut; a full re-slate is a scaffolded week, but individual slate work is quiet and quick.Natural Welsh slate re-roofing on a 3-bed semi in Ashford typically costs £6,500-£12,000 depending on property size and whether the existing batten and underlay structure is sound. Individual slate repairs run £150-£500. Spanish slate is available at lower material cost but has a significantly shorter lifespan. Free surveys and quotes.
Welsh slate is a dense, fine-grained metamorphic rock that has been quarried in north Wales for centuries. Properly installed, it can last 100-150 years. Spanish slate has a laminar structure that leads to delamination under freeze-thaw cycling, typically failing at 25-35 years. The material cost difference is significant but the lifecycle cost of Welsh slate over 100 years is considerably lower than Spanish slate replaced twice in the same period.
Yes. We source reclaimed Welsh slate from specialist suppliers for repair work on Ashford's Victorian and Edwardian properties. The colour and surface texture of reclaimed slate from the same quarry era is a better match than new Spanish slate and will last far longer. We specify reclaimed Welsh slate for all repair work on pre-1920 Ashford properties.
Yes. A common problem on Ashford period properties is previous repair work that used concrete tiles or Spanish slate that does not match the original Welsh slate. We remove the incompatible tiles, source a closer match in reclaimed Welsh slate and re-do the repair correctly.
Replacing a slate roof with matching slate on the same pitch is generally permitted development. Changing from slate to concrete tile, or any re-roofing in a conservation area, may require planning consent. We advise on the planning position at the survey stage.
Individual loose or sliding slates are fixed using either a code 4 lead clip (for slates where the hole has corroded or the nail has failed) or re-nailing where batten access allows. Clips are the standard repair for isolated slate failures. If a large proportion of slates are moving, the nail fixing system has failed systemically and re-roofing is the correct solution.
Correctly installed on a standard pitch: 80–150 years. The slates typically outlast the nail fixings and battens, which require replacement before the slate itself fails.
Not necessarily. Isolated slate failure on an otherwise sound Welsh slate roof is normal maintenance. The nails and battens should be assessed — if the nail fixings are at end of life across the slope, re-slating on new battens with reclaimed slate is more cost-effective than repeated individual repairs. We advise at the free survey.
Yes. We source reclaimed Welsh slate from Kent and Sussex demolition sources for period property repairs. Colour and surface matching confirmed before committing to repair.
Slate is appropriate for the pitch ranges on which it was originally designed: typically 25 degrees and above. On shallower pitches, the lap requirement increases and slate becomes impractical. We confirm suitability at the survey.
