Duquesa Ultra Natural Spanish Slate & Half Roof Tile Blue Black - 500mm x 375mm

The Duquesa Ultra Natural Spanish Slate & Half Roof Tile 500mm x 375mm is designed to be used alongside standard 500mm x 250mm Duquesa slate roof tiles, helping maintain correct bonding and alignment across a pitched roof.

This slate and a half tile is essential at verges, roof edges, and abutments where full slates cannot be used. It reduces the need for cutting smaller pieces, resulting in a neater finish and improved weather resistance across the roofline.

Quarried from the La Baña region in Northern Spain, this premium Hebra natural slate features a distinctive riven surface and textured edges, giving roofs a more traditional and characterful appearance. The blue black finish, with subtle vertical markings and a slight sheen, adds depth and visual appeal.

Manufactured to approximately 5–6mm thickness, this natural Spanish slate tile offers excellent durability and achieves a W1 S1 T1 rating, ensuring strong resistance to water absorption, thermal movement, and harsh weather conditions. It is a key component for a professional and long-lasting natural slate roof installation.
