Slates have been used to cover Roofs for hundreds of years, proving their durability for the purpose. Today Greenjackets supply Natural Slates sourced from three countries Wales, Canada and Spain. Welsh Slate is still regarded as the best Natural Slate in the world, although not produced in the quantities it once was has led to higher manufacturing costs, which in turn have made other Slates more popular. Spanish Slates have increasingly become more popular in the UK over the last few decades or so due to lower production costs and greater availability at source. Midway between Welsh and Spanish not only in price but also quality is the Canadian Slate. This Slate is readily available and has proved to be hugely popular since its introduction to the UK Slate market.
Manmade Fibre Cement Slates have also enjoyed great popularity over the years. They are available in 600mm x 300mm and 500mm x 250mm. Square Edged Plain Surfaced Fibre Cement Slates are the most common but they are also available with a Dressed Edge and Riven Surface. Fibre Cement Slates are also available in a number of colours.
