Site over-orders, cancelled jobs and careful strip-outs are where the best material bargains in the UK come from — this lot is one of them. This is unused, current-spec material — the only thing second-hand about it is the price tag logic.
The 168 kg CO₂e figure on this listing is calculated against quarrying or firing new roof coverings (natural slate ~13 kg CO₂e/m², concrete tile ~18 kg CO₂e/m²).
Put another way — about 991 km of driving emissions, or 8 tree-years of carbon uptake.
If your project tracks embodied carbon (BREEAM, Part Z readiness, or client ESG reporting), keep this listing reference as evidence of avoided emissions.
The headline saving on this listing (~168 kg CO₂e) 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 Sheffield 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 Sheffield Greenfield Contractors 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.
Sheffield Greenfield Contractors 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 Sheffield.
Allow 9% 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.
Sheffield Greenfield Contractors 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 new surplus lots at this price point — confirm the hold in writing so the seller doesn't re-list.
Yes — the ~168 kg CO₂e saving is calculable against the benchmark in the sustainability notes above; keep this listing URL as evidence for your embodied-carbon log.
