Details
Redland Grovebury Concrete Interlocking Roof Tiles
Redland Grovebury Roof Tiles have a double pantile shape which is quicker and easier to lay than a single pantile design. However, Grovebury concrete interlocking tiles still retain the traditional, gentle flowing lines of a classic pantile to blend easily and harmoniously into any environment.
With a low pitch, a wide variety of colours, and two different surface textures, the Redland Grovebury is an economical, ever popular choice for both new build and renovation projects.
Features

- Suitable for roof pitches as low as 15 degrees (Smooth finish only)
