Greys Roofing Preserving Britain’s Heritage with Charnwood Heritage Reproduction Stone Conservation Slate

greys artstone heritage logo

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.

Greys Heritage Charnwood Slate

greys heritage charnwood insetSwithland 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.

Designed to Diminish

Our slates are designed to give a random diminished course roofscape. A wide range of sizes ensure the roof can be laid using a random diminishing course technique providing greater weather protection and an authentic look.
