A typical slate has a top, bottom and two sides. The top of the slate is known as the‘ head‘ and the bottom the‘ tail‘, the head sits on top of the roofing batten and the tail sits on top of the slate beneath it. If the slate is not a uniform thickness the head is normally the thinner end and the tail the thicker. The front of a slate will display riven( bevelled) edges on all sides and this is called the‘ face‘, and the underneath is the‘ bed‘.
