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 ‘.
