FA Mitchell and Co  the roof tile specialists offer the CS10 Canadian Purple Slate for those looking for a precision cut, hard and durable natural roofing slate. 

The CS10 is quarried from the expansive slate deposits of Newfoundland in Canada. The Cambrian formation in the region has undergone great metamorphic compression resulting in the hardest and most durable slate available in the world. 

CS10 Canadian Purple Slate from FA Mitchell and Co is cut utilising laser guided diamond saws and pneumatic hammers to obtain a slate of consistent thickness and quality.

The exceptional performance of the CS10 slate is due to its mineral composition. The absence of calcium carbonates gives the slate total colour retention over its serviceable life. By achieving the highest classification in all international standards this slate has a 'serviceable' life in excess of 100 years.
