Brazilian Grey/Green Roofing Slate 500mm x 250mm

Create a distinctive, characterful roof with authentic Brazilian Grey/Green slate. Quarried in Brazil’s Minas Gerais region, these 500 x 250mm natural slates offer a unique grey-green colour with subtle natural variations that produce an attractive mottled or dappled effect once installed – often compared to traditional Cornish Delabole slate but at a more competitive price.

This prime-grade natural slate features a lightly textured or smooth flat surface with dressed edges, delivering a refined yet natural appearance suitable for both traditional and contemporary buildings.

Natural slate products can vary slightly in thickness and colour. Always allow a contingency for breakage during transport and installation. Due to the nature of Brazilian slate, cutting with an angle grinder or electric slate cutter is recommended, and hook fixing is often advised to reduce wastage. Install in accordance with BS 5534.
