Cwt Y Bugail Welsh Slate roofing is quarried from what is widely recognised as the finest quality and most durable slate deposit in the world. Cwt Y Bugail is located in Llan Ffestiniog on the edge of the Snowdonia National Park, North Wales. Cwt Y Bugail slate is generally dark blue grey in colour. The slate is naturally split along cleavage planes created by over 590 millions of years of intense pressure and heat to produce extremely strong roofing slates with a riven surface.
