It depends on site location and exposure. Generally, tiles are nailed at 25º and above and tail clipped below 25º. On all roofs, the perimeter tiles (i.e. tiles at eaves, verges, ridges and alongside valleys and abutments) should be nailed or clipped. Along the East Coast and in the midlands, every tile in alternate courses should be nailed or clipped. Along the west and south coasts, all tiles must be nailed or clipped (see map in brochure for boundaries).
