Marley Concrete Roof Tile
Concrete roof tiles for pitched roofs — the UK’s most-specified pitched-roof covering. Covers Marley’s interlocking and plain ranges (Modern, Edgemere, Ludlow Plus, Mendip, Wessex, plain tiles). Responsibly sourced to BES 6001; the concrete slowly reabsorbs CO₂ (carbonation) over its service life.
Carbon and evidence
Product Evidence
Evidence currently held for the Marley product record.
Recorded Carbon Result
A1–A3 GWP-total per m² of roof, per EPD (B1 carbonation reduces whole-life further) THIS FIGURE IS FORMAT-SPECIFIC — large format, 10 tiles/m², 50 kg/m². Medium format (16.5 tiles/m², 47 kg/m²) is 6.43 and SMALL format (60 tiles/m², 73.8 kg/m²) is 10.10 — 48% above the figure on this record.
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.

This figure is format-specific: it is the large format, 10 tiles/m² at 50 kg/m², declared in HUB-0860. The declaration carries a conversion table for alternative tile sizes and the other formats differ materially — medium format (16.5 tiles/m², 47 kg/m²) is 6.43 and small format (60 tiles/m², 73.8 kg/m²) is 10.10. Tile format rather than tile material is the dominant variable in a tiled roof’s carbon per square metre.
