Reclaimed Welsh slate roof tiles 20×10 (~200)
Genuine Penrhyn Welsh slates lifted from a chapel re-roof in Bangor. Hand-sorted, holes still good. 20×10 inch (Countess) — the most common UK size. Perfect for matching repairs.
Condition grade 7/10 (B-grade). Assessed by the seller at listing; figures below relate to this specific lot of 350 tiles.
Removed in good condition from a 1990s extension being re-tiled. Suitable for full-roof or batch repairs. Located in Cardiff — collection or arranged regional delivery available. Fresh to market — posted 28 days ago by Cardiff demolition Cardiff Urban Reclamation.
Surplus stock like this exists because projects over-order to avoid downtime — the saving gets passed to you instead of the skip. B-grade pricing reflects cosmetics, not performance — the defect notes below set out exactly what was downgraded and why.
No reuse CO₂ credit is claimed on this lot: it is unused stock, so the embodied carbon was committed at manufacture. Buying it still prevents waste — material sent to landfill or energy recovery delivers none of its embodied value.
With Part Z and embodied-carbon reporting moving up the agenda, documented reuse like this is increasingly worth recording in your project's carbon log.
The headline saving on this listing (waste avoidance) is benchmarked against quarrying or firing new roof coverings (natural slate ~13 kg CO₂e/m², concrete tile ~18 kg CO₂e/m²). That's the embodied-carbon figure — the emissions locked into new material at the point of manufacture, before it ever reaches your site.
In UK building terms, embodied carbon typically accounts for 40–60% of a project's whole-life emissions once operational energy is decarbonised. Reusing roofing like this lot from Cardiff bypasses the manufacturing stage entirely, which is why substitution consistently outperforms offsetting on lifecycle assessments.
For projects tracking against Part Z (the proposed embodied-carbon amendment to the Building Regulations), BREEAM Mat 01 credits, or the RIBA 2030 Climate Challenge, reused material counts at zero embodied carbon in the A1–A3 modules. Keep the seller invoice, this listing URL and the CO₂e figure together in your carbon file.
Beyond carbon: buying this lot from Cardiff Urban Reclamation keeps first-quality roofing out of the UK construction waste stream (currently ~62 million tonnes/year, per DEFRA). It supports the circular-economy supply chain — sellers who divert stock only continue diverting when there's a viable resale route.
Cardiff Urban Reclamation ring-tests on lifting — a sharp tap on a sound slate rings true, a dull thud means delamination. Spot-check your own sample on collection in Cardiff.
Allow 8% over your measured roof area for cutting, breakage and future repairs — with reclaimed stock the future-repair argument is the strongest.
Delivery is kerbside by default; loading to scaffold height needs a hiab or telehandler agreed with the seller in advance.
Cardiff Urban Reclamation issues a VAT invoice on collection or dispatch — bank transfer is standard, card on request. For anything over £500 we recommend a written spec confirmation before paying, so the exact roofing description and quantity are on record.
A short reservation (typically 48–72 hours) is usually possible with a 10% holding deposit. Surplus stock moves quickly, especially b-grade lots at this price point — confirm the hold in writing so the seller doesn't re-list.
The material itself carries the same certifications as merchant stock; document the reuse route in your carbon log even without a specific CO₂e figure — waste avoidance still counts under Part Z reporting guidance.
