BMI Redland Mini-Stonewold Interlocking Concrete Roof Tile

Redland Mini-Stonewold Interlocking Concrete Roof Tile

The Redland Mini-Stonewold Interlocking Concrete Roof Tile is a versatile, modern alternative to natural slate, offering clean lines, robust performance and long-term reliability. Designed for use on pitched roofs and suitable even for external wall cladding, this concrete tile provides a sleek, uniform appearance that works beautifully on both contemporary and traditional properties. Manufactured by BMI Group UK Limited, the Mini-Stonewold tile meets the harmonised standard BS EN 490:2011, ensuring consistent quality and dependable weatherproofing. Its interlocking design enhances installation efficiency while delivering excellent wind resistance and water shedding performance. With a minimum pitch capability of 17.5°, it is a practical solution for a wide range of roof designs and building projects.

Colour Options

The Mini-Stonewold tile is available in three attractive tones, offering style choice without compromising durability: Slate Grey – A refined, modern shade reminiscent of natural slate. Tudor Brown – A warm, traditional colour that complements rustic and heritage builds. Farmhouse Red – A richer, more distinctive tone for classic and characterful roofscapes.

Performance & Durability

With a coated surface finish, this concrete tile provides enhanced colour stability and protection against weathering. Its precise interlock and strong concrete composition ensure long-lasting performance, while excellent dimensional accuracy contributes to a clean, consistent roof finish. Each tile measures 418mm x 334mm, with a hanging length of 398mm, ensuring flexible installation options. The system accommodates headlaps between 75mm and 125mm, allowing installers to adapt to pitch requirements from 17.5° up to vertical (90°). When laid at maximum gauge, coverage is highly efficient at 9.9 tiles per m², and the roof build-up remains durable and structurally robust.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
