There are many cheap slate roofing products on the market from various parts of the world including Spain and China, but they are a false economy. Generally they do not last well due to high levels of iron pyrite which is unstable when exposed to the elements and can contaminate water run-off. They are also very brittle and have high water absorption, causing leaks and roof damage.

We only sell genuine slate roofing products from reputable quarries which have stood the test of time and meet UK, USA and European standards.
