Cornish Slate

Natural Cornish Roofing Slate



Delabole slates have a natural riven texture, new slates will weather to a pleasing mellow shade


Delabole Slate Quarry has exclusive access to the very best of Cornish slate reserves. There is no other slate quite like it, which is probably why the quarry has operated for 800 years or more and is still the oldest and largest slate quarry in both Cornwall and England. They still make their famous roofing slate in the traditional way. Hand-made by Cornish craftsmen using skills handed down from father to son for generations.
