1918 Welsh Slate Roof

We image there is more than enough slate here to accommodate most projects.

Geographically, Welsh slate was formed as deep-water mudstones between 550 and 470 million years ago, making it older than slate in Spain. 

It comes in two lithotypes - B1 in Cwt-y-Bugail, which is blue/grey, and R1 in Penrhyn, which is heather/purple. Penrhyn slate is known to be quite expensive and cane bright and striking when new. The colors will change slightly over time while retaining their distinctive natural beauty. 

Welsh slate is available in three grades based on the thickness to which it’s produced – Capital, County and Celtic.

Celtic Grade Welsh Slate is the thickest available choice at 9mm thick. Next comes, County Grade Welsh Slate at 7mm thick, followed by Capital Grade Welsh Slate at 5.5mm thick.
