All of our products have been designed in consultation with professional roofers and architects to achieve an easy to lay slating format, which will result in a coursed and diminishing stone slate roof.
Our stone ranges tend to be used mainly in Pennine areas for high quality builds, but the slate sells nationally through builders’ merchants, individuals renovating barns and farm houses. Our new Westmorland Green and Welsh Heather ranges of slate are proving particular popular in the Cumbria region as these slates suit this landscape.
As with our stone products, each individual slate is hand crafted using a mould taken from natural slate. The fine edge detail and textured surface combines with realistic colouration to create an attractive alternative to natural slate. The tensile strength that results from glass reinforced cement construction allows the slates to be cut easily, without cracking or breaking and offers a 33 per cent saving in weight compared with the natural equivalent.
Our slate is not only natural in appearance but also long lasting. “Because many of our competitors use traditional concrete, their slates aren’t protected from the elements, which will expose the aggregate. All the slates in our range have been successfully tested for durability, colour, strength, fire and freeze thaw.

We’re confident our product is durable enough and manufactured to the highest of standards that we give a 25 year manufacturer guarantee.

Colour and Efflorescence COLOUR: Stone and Slate colours on this website are subject to the limitations of monitor quality and are for guidance only. EFFLORESCENCE: The phenomenon of efflorescence has been a problem to the construction industry for decades. The cause lies in the basis chemistry of all Portland cements. Efflorescence in Greys Artstone products is a temporary phenomena and will disappear over time.
