Slate Roofing in Witney
Slate Roofing Specialists in Witney
Slate roofing in Witney demands material and specification knowledge that standard concrete tile re-roofing does not. Original Welsh slate on Victorian and Edwardian properties, Cotswold stone slate on period properties in the surrounding villages, and the specific fixing and bedding requirements for each type — we work with all of them regularly across Witney and the wider Oxfordshire area.
Welsh Slate Matching
Original Welsh slate on Witney's Victorian and Edwardian properties is typically Penrhyn or Ffestiniog grade — a blue-grey to blue-purple colour with a characteristic smooth riven surface. Matching repair slate requires sourcing the correct grade and thickness. We maintain supplier relationships for both new and reclaimed Welsh slate and assess on every survey before recommending a material specification.
Slate Fixings and Longevity
Original Welsh slate on Witney properties can last 150 years or more — the slate itself rarely fails. The nails corrode first. When we re-roof with new or reclaimed Welsh slate, we use copper or stainless steel nails throughout. Copper nails are traditional and correct for heritage work; both last the lifetime of the slate and eliminate nail sickness as a re-roofing trigger.

Slate in Witney is the historic covering on the older and larger houses around Church Green and the High Street; the failure is almost always nail sickness — the fixings corroding — rather than the slate itself, so we refix or strip-and-relay, reusing sound original slate wherever we can and matching new where we cannot.
Correct grade, thickness and colour matched on every repair job.

10-Year Guarantee
All slate work covered by our written 10-year workmanship guarantee.
Witney sits on the Cotswold fringe, and its historic roofing reflects it — the old core around Church Green and the High Street, including the former blanket-mill buildings, carries Cotswold stone-slate as well as Welsh slate, a heavier and more specialised covering than the smooth Welsh slate of the valley towns. Stone-slate roofs are laid in diminishing courses and bedded differently, and re-laying one is skilled heritage work that must respect the original coursing. On the Welsh slate of the Victorian frontages the issue is standard nail sickness. Witney sits on the Windrush in a damp valley setting, so moss establishes readily on both stone and Welsh slate and holds water at the laps. Around Church Green and the High Street conservation frontages we match materials and arrange permit scaffold; on the Madley Park and Cogges estates any slate is modern and far more straightforward. We refix to BS 5534 throughout and re-lay stone-slate to its original coursing where the roof calls for it.
Honest advice
How to Tell You Need Slate Roofing
In Witney, the roofs we are called to reflect the town's own building character. Witney's Cotswold-edge character shows in the stone and stone-slate of its historic core around the Church Green and High Street — including former blanket-mill buildings — ringed by large modern estates at Madley Park and Cogges in concrete interlocking tile. Witney sits on the Windrush in west Oxfordshire on the Cotswold fringe, a damp valley setting where the stone-slate roofs of the old core and riverside moss growth are the distinctive local factors.
Slate in Witney is the historic covering on the older and larger houses around Church Green and the High Street; the failure is almost always nail sickness — the fixings corroding — rather than the slate itself, so we refix or strip-and-relay, reusing sound original slate wherever we can and matching new where we cannot. Where only a few Witney slates have slipped from isolated nail failure, targeted refixing is enough; a whole slope should be stripped only when nail sickness is genuinely widespread, and we will show you the evidence before recommending it.
Slate is the dominant historic covering on much of North Oxford and the larger Victorian and Edwardian properties. Slate itself outlasts its fixings, so the failure is usually the nails, not the slate.
Individual slates slipping and appearing in the gutter or on the ground
A scatter of gaps across an otherwise sound slate slope
Damp appearing after driven rain rather than steady rain
Delaminating or flaking slates on an exposed slope
A previous repair using the wrong-size or mismatched slate
When it is not the answer: If only a few slates have slipped from isolated nail failure, targeted refixing is enough — a whole slope should only be stripped when nail sickness is genuinely widespread. Read the full guide.
Nail sickness on slate — strip-and-relay refixes original slate to BS 5534.The process
How a Oxford Slate Roofing Job Runs
1. Survey
Every Witney job follows the same disciplined sequence, adapted to the property — a period roof around Church Green and the High Street gets more survey and matching time than a modern estate roof, but the steps are the same.
We assess the slate condition and, crucially, the nails — testing how widespread any nail sickness is across the slope.
2. Written quote
A fixed-price quote for refixing, matched replacement or strip-and-relay, with slate provenance specified for conservation areas.
3. Source matched slate
Where replacement is needed, we source matched Welsh slate by grade and colour before starting.
4. The work
We refix or relay using copper or stainless nails to BS 5534, reusing sound original slate where possible.
5. Sign-off
We clear the site and hand over the 10-year workmanship guarantee.

Access
Scaffold, Skips & Street Access
Witney's Church Green and High Street conservation frontages, with their Cotswold stone and stone-slate, need matched materials and permit scaffold; the Madley Park and Cogges estates are open modern layouts for tower access.
Slate work needs scaffold for anything beyond a few slipped slates, both for safe access and to stack and sort the slate. Scaffold is specified for: strip-and-relay, re-roofs, and any work beyond refixing a handful of slates - always itemised in your written quote, never a hidden extra, and we arrange it.
Central Oxford's medieval street core and the tight Victorian terraces of Jericho and off the Cowley Road mean rear-access scaffold and permit-controlled pavement space are the norm on many jobs. Pavement scaffold and skip permits go through Oxford City Council; allow a few working days on streets like Holywell Street, Ship Street, St Michael's Street, Merton Street where space is tight.
Access in Witney's old core is shaped by the Cotswold-stone conservation frontages around Church Green and the High Street, where matched materials and permit scaffold are the norm; the Madley Park and Cogges estates are open modern layouts for tower access. We arrange any permit, itemise the scaffold, and factor the heritage constraints into the quote, so a Witney job is costed to the real access at your particular property.

The same written guarantee applies to every roof we complete in Witney and the surrounding villages.
Slate work carries a 10-year workmanship guarantee; reclaimed and new Welsh slate itself has a service life measured in generations.
Covered: workmanship for 10 years, in writing, transferable if you sell.
On top: manufacturer warranties on materials (terms vary by product).
Not covered: storm or impact damage - that is an insurance matter, and we will document it for your claim.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Good to know
Disruption, Mess & Weather
Scaffold up for larger jobs, careful sorting of slate on site, and a skip for waste — we protect the grounds and keep the site tidy daily. You do not need to stay home for external work - we just need power and access agreed in advance.
Slate work runs through the year in settled weather; on a strip-and-relay we only open what we can make weathertight each day. The Thames and Cherwell valley setting keeps ambient humidity high, so drying times for mortar, GRP and biocide run longer here than on the surrounding higher ground.

FAQ
Slate Roofing Witney — Common Questions
Replacing a small number of slates in Witney costs £200–£900 depending on quantity and access. A full re-roof with Welsh slate on a standard 3-bed semi costs £10,000–£16,000. Larger period properties cost more. Free survey and written quote provided.
Yes. We assess the grade, thickness and colour of existing slate on every survey and source matched material from our slate suppliers. For conservation area and listed properties where specific grade approval is required, we advise on this before ordering.
Correctly installed Welsh slate with copper or stainless fixings lasts 100–150+ years. Original Victorian and Edwardian slate in Witney is already 100–130 years old and still performing on well-maintained properties. The nails fail before the slate — which is why fixing specification matters.
Yes. We carry out slate roofing on listed buildings across Witney and Oxfordshire. We advise on Listed Building Consent requirements at the survey stage and work with approved materials and specifications.
Cotswold stone slate is natural limestone split into thin slabs for roofing — found on period properties in Woodstock, Witney and the surrounding Cotswold villages. It is a different material from Welsh slate with its own failure modes (delamination from freeze-thaw cycling) and sourcing requirements. We carry out Cotswold stone slate work across the region.
We use copper or stainless steel nails for all slate roofing work in Witney. Copper nails are traditional and correct for heritage work; stainless steel provides the same longevity at lower cost. Both materials last the lifetime of the slate. We never use galvanised or ferrous nails on slate roofs.
For replacing a small number of individual slates, scaffold is not always necessary and we assess access requirements on the survey. For re-roofing or significant repair work, scaffold is required and is included in the written quote — never charged as a surprise extra.
Slate roofing in Witney appears on Victorian and Edwardian properties in the older areas of the town — Cotswold market town core and 1990s concrete tile expansion estates. At 100–130 years, original Welsh slate on Witney properties is typically sound structurally, but the nail fixings have corroded and individual slates have slipped. We assess grade, colour and thickness on every Witney survey and source matched Penrhyn or Ffestiniog slate for repairs.
Witney's Conservation Area and Slate Specification
Conservation area properties in Witney require like-for-like material replacement on street-facing slopes — Welsh slate cannot be replaced with fibre cement or synthetic slate without prior notification to the council, which is unlikely to be approved. We check for every Witney survey address and specify compliant materials in the written quote.
Nail Specification for Witney Slate Roofs
We use copper or stainless steel nails for all slate work across Witney. Original Victorian slate on Witney properties was fixed with copper nails — a traditional specification that lasts the lifetime of the slate. We never use galvanised or mild steel fixings on slate roofs, which corrode within 30–50 years and create nail sickness on the slate deck.
