We have been producing and supplying natural roofing slate since 1892. With over 130 years of experience, our team of more than 1,500 dedicated professionals brings deep expertise and a true passion for natural slate.

Natural Roofing Slates

No roofing material compares to natural slate. It withstands extreme temperatures, heavy snow loads, and offers the highest fire resistance rating (A1), while remaining completely waterproof.

If you’re looking for a long-lasting, low-maintenance roofing solution, slate is the ideal choice.

As a highly durable and weather-resistant material, its color and natural sheen will not fade or deteriorate over time—even in the harshest conditions.

With a 100-year lifespan and low embodied carbon, natural slate is one of the most sustainable roofing options available, as supported by Life Cycle Analysis studies from the University of Bath.
