Welsh Slate is recognised as the best quality roofing slate in the world, and will give you a roof that will last more than a lifetime.
This is because its extraordinary geology gives it unique physical properties which, when combined with generations of skilled quarrymen, create a roofing slate which has been tested over the centuries by the harshest climates imaginable. Available in three thickness grades: Capital; County; and Celtic; to suit the projects requirements. If you need help in understanding the precise benefits a Welsh Slate roof will provide then please call us - we'll be happy to explain more.
Welsh Slate was laid down as a sediment some 550 to 470 million years ago, heated and compressed by the same huge tectonic forces that created the Snowdonia mountain range. The resulting unique raw slate material contains no reactive minerals and it is this, combined with its ability to be split into very thin flat sheets, that make it the ideal roofing slate. This is because it is light weight, extremely durable and has a natural beauty which only gets better with time. This is why Welsh Slate has been the roofing choice of the world for centuries.
Welsh Slate roofing product is only available from two quarries, each quarries product retains the unique physical characteristics but has its own individual, distinctive natural colouring; Penrhyn® - a Heather Blue slate, and Cwt-y-Bugail - a dark blue grey slate.
