The thickness and unique surfaces of the Stoneleaf Celtic Grey results in a roof finish that has texture depth and character.

The Stoneleaf Celtic Grey Slate is a product with a rugged textured surface, hand split from premium quality Grade 'A' rock, formed 400 million years ago during the Ordovician period, the same time as Ffestiniog Welsh Slate.

Increasingly the preferred choice of specifiers, developers, private homeowners and conservation officers, the Celtic Grey adds character and charm to the most prestigious properties.

At approximately 54kg/m2 when laid, it is far heavier than many other roof slate finishes, making it less liable to wind damage in our increasingly turbulent climate.

When we were contacted by the German company who were building this magnificent house in Sunningdale, Berkshire, we offered various choices in terms of colour, thickness and texture.

Having looked at other projects supplied by Stoneleaf in the local area, the client chose the Celtic Grey due to its quality, colour and distinctive rugged texture. A team came over from Germany to carry out the roofing works, which involved some unusual detailing on the ridges and hips – common in Germany but not in the UK.

The result is a magnificent roof in keeping with the property and its setting.
