Inhabitants of Northern Wales are believed to have been the first to take advantage of slate’s natural cleavage for the production of roofing slate around 1300 A.D. 

Over several centuries the Welsh developed a proud tradition of slate production, one that continues to this day.

In the mid-1800s, Welsh immigrants brought their slate-working experience to North-east U.S.A., starting what was to become a major industry in the area.


Heather Blue/Purple slate, quarried in the “Slate Valley” region of Vermont is a very unique and popular slate.

Has been used on the most exposed roofs in the U.S.A., North America and Europe for more than 200 years.

Because of its superior properties and unique heather blue or purple-heather appearance, it has proven to be a true alternative to the Welsh “Blue Bangor” slate but with a significant cost saving.


Vermont Heather Blue Natural Slate is quarried exclusively for Slate Supplies Ltd., we are the only distributor for this slate in UK and Ireland.

The Vermont Heather Blue Natural Slate is produced from block extracted from a single family owned & run quarry.

The raw block is then cut in the production sheds to ensure that the slates are made “on the grain”.

This greatly improves strength, longevity and workability of the finished roofing slate.
