The lifetime of a building begins with a choice of materials and for hundreds of years, architects and designers have been inspired by the natural beauty of slate. Welsh slate roofing is extracted from some of the worlds finest deposits. Formed up to 590 million years ago, each peice of slate has its own unique fingerprint that reflects the power and presence of the landscapes from which it was hewn. The quality of Welsh slate roofing is such that even after 100 years of use at least 50% of Welsh slate is typically re-used. There are buildings around the world which have Welsh slate roofing tiles which are several hundred years old. Welsh slate is available in 3 colours, Heather Red, Heather Blue and Dark Blue Grey.
Spanish roof slate accounts for 90% of Europe's natural roofing slate. This high quality slate will suit most projects with a blue grey desired colour.

A.Armstrong Roofing Contractors carried out refurbishment work to this terraced property. The roof covering we decided to go with was Spanish slate due to customer budget / product life expectancy requirements. We gave the roof a complete overhall all lead bays and chimney work leaving no maintenance required for a number of years. All work carried out was within schedule and to the highest of standard.
