Manufactured in the UK
Greys Artstone are Proud manufacturers of the Greys Heritage range of artificial stone roofing products.
The Range is crafted to give an authentic roofscape, offering detailed moulding, a choice of colours and a range of sizes. The glass fibre cement construction provides a light yet durable roofing material. An easy to lay format and a range of compatible products, including ridges and in-line ventilation systems, create an extremely versatile and cost effective alternative to natural products. Each individual slate is hand crafted using moulds taken from stone slate originals. As with natural stone, shades vary, with no two slates being identical. This, combined with the surface detail and hand colouring, ensures a truly authentic roofscape.
Greys Heritage Reproduction Stone roofing slates have been designed in consultation with professional roofers and architects, to achieve an easy to lay slating format, resulting in a coursed and diminishing stone slate roof.
The slates are constructed from Glassfibre Reinforced Concrete (GRC) producing a strong and durable slate weighing only 65kgm2.
Their construction allows them to be cut easily, without cracking or breaking, and looks like stone when cut. The construction of our slates makes them 20% lighter than the original stone, saving on labour and timber costs. In real terms that means 16m2 of our slates per ton compared to 7m2 per ton of natural stone slates.
Due to reduction in quarrying of Natural Cotswold Stone over the decades both new and second-hand stone, have become increasingly costly and therefore in very short supply.
Due to this shortage, and the lack of a suitable alternative, that the Greys Heritage Cotsway range of slates is now being manufactured by Greys Artstone Ltd. This product is an excellent alternative to real stone and has been specified on new houses and listed buildings throughout the Cotwolds and surrounding areas to replicate the rustic beauty of the original Cotswold Slate, that has given the area its distinctive charm.
The Slates are designed to blend in with original Cotswold stone slates, with their Random Diminishing appearance.
Unlike other imitation tiles, our products sit well amongst natural Cotswold stone, and will weather over the years to become indistinguishable from natural stone tiles.

Collyweston stone slate is a traditional roofing material found in central England. The slates are were quarried near the village of Collyweston in Northamptonshire, near Stamford and close to the borders of Lincolnshire and Rutland.
The stone was traditionally mined and left outside for three winters until the frost revealed layers that could be broken ("clived") into flat slates, this gave then a very similar appearance to that of Cotwold Stone Slates with sizes identical to create the Random Diminishing roofscape it is renowned for. The Greys Heritage Rutland is coloured to replicate this discticive slate. With sizes larger at the bottom of the roof scape and smaller as it is laid to the ridge, and random widths per course, its rustic appearance complements all architectural designs.
The Greys Heritage Range is supplied with batten schedules to create an easy to lay format that is traditionally pegged as a Natural slate would be.
The slate has all the characteristics of a natural random diminishing slate with all the advantages of a modern building material.
Swithland slate roofs are an important feature of historic buildings in the East Midlands. With the closure of the two main Pit Quarries back in the 1800’s, the East Midlands have been eagerly awaiting a product that replicates the unique and rustic beauty of the original Swithland slate that has given the area it’s distinctive charm.
The reproduction slates are faithful to the original in terms of colour, texture and performance.
All the slates in our range have been successfully tested for durability, colour, strength, fire and freeze thaw. Many of our competitors use traditional concrete, their slates aren’t protected from the elements, which will expose the aggregate over time. See the example below.
In a recent document The International Glassfibre Reinforced Concrete Association recommend that for good quality GRC, ductile lifetimes of at least 60-80 years can be confidently expected in UK weather conditions. (Source: www.grca.org.uk).
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.
