The Stoneleaf Classic

The Stoneleaf Classic is a natural roof slate with a lightly textured surface, blue grey in colour and very regular in thickness.

The Classic has the traditional look of natural slate, whilst being easy to lay due to the excellent selection and sorting process at the point of production.

The Classic has passed the rigorous process to achieve approval for use in the Snowdonia National Park. Deemed hardy enough to withstand harsh environments within the Snowdonia National Park and offers a robust alternative with the equivalent colour, texture and weathering characteristics to the Welsh slate once quarried from Ffestiniog and Maenofferen quarries.

This approval gives specifiers and roofers confidence in the quality and performance of the slate, knowing it will last a lifetime and still look good to withstand all weather conditions.

The exceptional quality of the sourced rock enables the Stoneleaf Classic to be produced in larger formats, up to 600 x 450mm.
