Greys Artstone reproduction stone and slate products are hand crafted to give an authentic roofscape. Detailed moulding, a choice of colours, and a range of sizes create a coursed and diminishing stone slate roof. 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.
