Birkdale Fibre Cement Roof Slate

A smooth surface and dressed edges offers a traditional and pleasing look at an affordable price, using nail and rivet fixing down to 20°.

The combination of colour, edge finish and design flexibility that the Birkdale offers means it is ideal as both a roofing and cladding solution, used on numerous projects including the Tally Ho training centre in Birmingham and the Holcombe Moor Army base near Bury.

We also have a low pitch Birkdale fibre cement slate option that can be used for low pitch designs down to 15° (with hook fixing)* offering the designer and contractor more flexible aesthetic and installation options.
