Greys reproduction roofing slates have been designed in consultation with professional roofers and architects, to achieve an easy to lay and uniform slating format. 
Greys Artslate Roofing Slates are constructed from Glassfibre Reinforced Concrete (GRC) producing a strong and durable slate weighing only 30kgm² . 
Their construction allows them to be cut easily without cracking or breaking and looks like slate when cut.

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