Sierra Slate

Sierra natural slate is an exceptional quality slate and one of the very best options available from North West Spain. It is a flat, smooth blue grey slate which is mined (as opposed to open quarried) in deep slate tunnels near to Ourense, Galicia and is a popular seller throughout the UK and Ireland. It is readily available in both 50×25 and 60×30 dimensions.

The Sierra slate is sold, not only in the UK and Ireland, but all over the world and indeed is a market leader in Germany which has some of the strictest quality criteria for natural slates anywhere in the world.

The Sierra Spanish slate is a very consistent natural slate and requires minimal grading, making it a popular choice for roofing contractors, self-builders and architects.  Available in Premium 5mm or Heavy 7mm.

Sierra Slates fully comply with BS 12326-1:2014 (W1, S1, T1), and come with a full quarry backed guarantee.
