What's good & bad

SLATE CAN NATURALLY BE CUT VERY THIN,

WHICH MEANS THE ROOF JOISTS WHICH SUPPORT IT CAN BE THINNER AS WELL

BECAUSE SLATE IS ONLY FOUND LOCALLY IN SOME PARTS OF THE UK, IT CAN USE A LOT OF ENERGY TO TRANSPORT IT TO OTHER AREAS

But slate is one of the best because it comes naturally out of the ground and only needs to be cut to size to use it as a roof tile.

Overlapping

tiles

Slates or tiles need to be laid so that they overlap, to stop rainwater from leaking through the gaps between the tiles.

Penrhyn quarry in North Wales was once the

largest slate quarry in the world.
