How to Tell You Need Slate Roofing

In Cowley, the roofs we are called to reflect the town's own building character. Cowley is defined by its inter-war and post-war workers' housing built around the car works — long runs of 1920s–30s semis and terraces off the Cowley Road and Between Towns Road, largely clay tile and early concrete interlocking, plus later council estates. Cowley sits on the gentle rise east of the Thames, drier than the central river valley, but its dense mature street trees drop heavy leaf fall that blocks the long terrace gutter runs every autumn.

Slate in Cowley is the historic covering on the older and larger houses around the streets off the Cowley Road; 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 Cowley 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.

How a Oxford Slate Roofing Job Runs

How Long Does It Take?

Slate work pauses in high wind — handling slate at height in a gust is unsafe; we build weather margin into the programme.

Scaffold, Skips & Street Access

Along the terraced streets off the Cowley Road, rear access is limited and skips or scaffold often need Oxford City permits for the pavement; the more open post-war estates towards Blackbird Leys give easier driveway 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.

• Extent of nail sickness across the slope
• Proportion of original slate reusable

Worked example: A strip-and-relay of the front slope on a Victorian terrace in Jericho, reusing around 80% of the original Welsh slate with new stainless fixings, typically runs around £3,800.

Staged payment on strip-and-relay and re-roofs against completed work; materials on site first. VAT included in the written quote.

Your Guarantee, Explained

The same written guarantee applies to every roof we complete in Cowley 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.

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.
