Welsh Slate

Welsh Slate is widely recognised as the finest natural slate in the world, and uniquely is around 500 million years old.

Natural slate from Welsh Slate’s Penrhyn, Ffestiniog and Cwt-y-Bugail quarries produces the finest roofing slates in the world. Its durability, which sets it apart from other slates, is derived from its density and the geological formation found in that part of North Wales.
Direct Slating can supply the full range of Welsh Slates.

Welsh slate benefits from a number of highly practical properties that make it an exceptional roofing slate. It is the most durable slate in the world with a normal productive life of more than 100 years. It is waterproof and largely unaffected by normal extremes of temperature, highly resistant to acids, alkalis and other chemicals and it is colour-fast and non-fading.

Welsh Slate’s unique features allow a fully functional long-lasting roof combined with an aesthetically pleasing appearance. In addition, roofing contractors benefit from the method of production which means only a low level of on-site grading is required, saving time and money, and the number of breakages on site is typically few, again saving time, money and waste.

There are 3 main colours that naturally arise from the quarries of Welsh Slate used for roofing slates:

Penrhyn Heather Blue, Penrhyn Heather Red and Cwt-y-Bugail Dark Blue Grey.

Penrhyn Heather Blue

One of the traditional Penrhyn colours, also known as Bangor Blue, and perhaps the best well known Welsh Slate colour.


Penrhyn Heather Red

A traditional Penrhyn colour used for roofing and architectural products.



Cwt-y-Bugail Dark Blue Grey

The traditional Ffestiniog colour, a dark blue grey with occasional white veins which makes the material ideal for all applications.
