The industry consensus protects all parties, from contractors working with reliable materials to clients investing in roofs designed to last. For projects where durability and performance are paramount, genuine European metamorphic slate remains the proven choice.

Independent authorities across the roofing industry — including the NFRC and leading geologists — have clarified that what is often sold in the UK and Ireland as “Brazilian slate” is actually a different type of rock: metalutite.
