Schist Roof?

I accidentally saw an article about a slate roof. Maybe there was already such an idea, but it can be updated) It would be cool to add such roofing material.

Something like in the video

Ya it would be cool if we could make stone tiles for roofing. Could also then also add clay ones. I do not know how well the textures would look, but it is a cool idea.
