Specialist slate repair, matching, and re-roofing. Welsh, Spanish, and reclaimed slate for Victorian and Edwardian properties.
East London has one of the UK’s highest concentrations of natural slate roofs. Victorian terraces across Hackney (Mare Street, Graham Road, Amhurst Road), Bow (Roman Road, Tredegar Road), Bethnal Green (Globe Road, Vallance Road), and Shoreditch (Curtain Road, Rivington Street) were roofed with Welsh slate from the Penrhyn and Ffestiniog quarries in North Wales.
These slates have survived 130–160 years but are now showing their age. Nail sickness (corroded iron fixings) is the dominant problem, causing slates to slip and shatter. Delamination — where the slate layers separate and flake — affects the most weathered slopes.
Matching existing Victorian slate requires sourcing from the same geological formation. Welsh Penrhyn purple and Ffestiniog blue-grey are still quarried and available. For budget-conscious repairs, high-quality Spanish slate offers an excellent visual match at 30–40% lower cost. Reclaimed Welsh slate — salvaged from demolitions across London — provides the perfect match for conservation area work in Hackney, Walthamstow, and Wanstead.
The densest concentration of natural slate roofs in East London runs through the Victorian heartlands:
Hackney: Mare Street, Graham Road, Amhurst Road, Pembury Road, Richmond Road, Dalston Lane, Cecilia Road, and the streets around London Fields and Clapton. Predominantly Welsh Penrhyn purple slate in 500×250mm and 600×300mm sizes.
Bow: Roman Road, Tredegar Road, Coborn Road, Fairfield Road, Old Ford Road. A mix of Welsh and Westmorland slate on the grander houses, with Welsh blue-grey on the workers' terraces.
Bethnal Green: Globe Road, Cambridge Heath Road, Vallance Road, Victoria Park Square. Georgian and early Victorian roofs with hand-cut random-width slate — the most challenging to match for repairs.
Shoreditch: Curtain Road, Rivington Street, Hoxton Street. Warehouse conversions with original industrial-scale slate overlaying the underlying timber or iron roof structures.
No two quarries produce identical slate. Welsh Penrhyn purple has a distinctive heather-tinged grey that no Spanish or Chinese slate replicates exactly. Ffestiniog blue-grey is a cooler, darker slate. Reclaimed Victorian slate — salvaged from London demolitions — provides the closest match because it has weathered in the same pollution and climate conditions as your existing roof.
For spot repairs (1–20 slates), we source from our stock of reclaimed London slate and quarry-matched new Welsh slate. For full re-slating, we can source bulk quantities from Penrhyn, Ffestiniog, or (for budget-conscious projects) high-quality Spanish quarries that produce visually similar slate at 30–40% lower cost.
If fewer than 20% of slates are affected by nail sickness or delamination, targeted repair with copper nail re-fixing is the right approach. If 20–40% are affected, a phased repair programme over 2–3 years can extend the roof's life cost-effectively. Above 40%, full re-slating is the better investment — the cumulative cost of repairs exceeds replacement within 5 years, and you get a new roof with a 10-year guarantee and an expected lifespan of 80–150 years.
