How is slate formed?
Slate is a natural material formed millions of years ago. Slate is a fine-grained metamorphic rock formed when ocean or riverbed sediments were compressed and heated by the earths crust. Its main constituents are Quartz, Chlorite, Mica and Calciate.
Slate is blasted from quarries in large slabs, and then cut into smaller, more manageable slabs before being split to form roofing slates.
A quality building material
There are many countries producing slates and the quality of the slates between countries varies significantly. In our opinion, Welsh slate is far superior to that you would find from the Far East. Welsh slate benefits from a number of highly practical properties that make it an exceptional roofing material. It is the most durable slate in the world with a useful and efficient life of more than 100 years.
Slate roofs are known to be ‘one of the most fire resistant roofs’, as slates are completely fire proof, which is a big advantage when preventing fires caused by air borne sparks from fireworks, wild fires or from adjacent property fires.
Slates come in many different sizes and colours such as grey, green, purple and black. Historically roofing slates were fixed with wooden pegs, a practice that evolved into two radically different methods. In the UK the pegs were replaced by nails and on the continent they were replace by ‘s’ shaped metal hooks. Years ago each size of slate had a its own name such as, Duchess – 24” x 12”, Countess – 20” x 10” and the Viscountess – 18” x 9”.
