We already know that there are several types of roofing slate in the world, and that they are not all the same in terms of quality and versatility. As we have said before, not all roofing slates are slate. Slate for roofing is a metamorphic stone that can be split into thin tiles to be […]

The useful life of natural slate can exceed 100 years, but what about its appearance? According to laboratory tests, it is as if time stands still for natural slate: its colour and shine remain unchanged even under the most adverse climatic conditions, which its roofing alternatives such as ceramic and concrete cannot match.
