Cwt-y-Bugail Welsh Slate Roofing
Cwt-y-Bugail produces a beautiful dark blue-grey with occasional white veins and unique riven texture. Located east of Blaenau Ffestiniog in North Wales, it has been producing slates from 1840, and was formed by the Ordovician slate beds laid down over 470 million years ago. The Cwt-y-Bugail slate has a distinctive banding known as relic bedding and gives an extremely uniform unfading appearance on the roof. Although without the immense capacity of its sister quarry at Penrhyn it is still able to produce large volumes of roofing slate.
Cwt-y-Bugail Welsh Slate comes in three thickness grades to suite your projects specific roofing needs.
Which grade of Cwt-y-Bugail Welsh Slate do you need?
Cwt-y-Bugail Welsh Slate roofing is available in three thickness grades: Capital, County, and Celtic. The thickness of the three specific grades is to suite the range of different roofing project requirements.
The quality of the stone will allow production of roofing slates in excess of 1 metre in length, but the majority of the production is focused on the core production sizes (500 x 300 mm, 400 x 250 mm and 300 x 200 mm) in three thickness grades; Capital (5.5 mm), County (7 mm), and Celtic (9mm). Each grade of slate has a subtly differing character, but all have the intrinsic quality that makes Cwt-y-Bugail Slate the envy of the slate world.

Cwt-y-Bugail Capital Grade
Cwt-y-Bugail Capital Grade is the thinnest production Welsh Slate at 5.5 mm.
Only limited parts of our quarries will make this slate with its fine-grained riven surface. The thinness of the slate gives a flat uniform finish to the roof and was traditionally the material transported to the more distant markets such as London, continental Europe and even as far away as Australia and New Zealand.
Cwt-y-Bugail County Grade
Cwt-y-Bugail County Grade is the main production thickness at Welsh Slate at 7 mm thick.
The surface texture is similar to the Capital Grade, but the slightly thicker leading edge gives more focus to the slate on the roof. Traditionally sold in the Midlands and North West of England it is now sold widely across the World.
Cwt-y-Bugail Celtic Grade
Cwt-y-Bugail Celtic Grade is the thickest of Welsh Slates production at 9 mm.
As its name suggests its natural home is on the roofs of buildings facing the prevailing westerly winds in Ireland, Scotland and Wales. The more textured surface and thicker leading edge give the slate a more rural appeal but the Celtic Grade slate does find its way into city centres where it can be used to make a statement.
