Abstract: A roof clip (205, 305) for roof tiles (1, 2) is disclosed in which a fastener (4) having a shank (24) which passes into a timber batten (3), or timber deck (51) is used to anchor the clip. The fastener is preferably preassembled with the clip to form an assembly able to be handled by the tile installer. The shank 24 passes through a base (206) the length of which pre-sets the distance between the batten and hook (107, 207). The distance between the hook and base is adjustable by means of a ratchet mechanism (229, 329). Consequently one clip can be used with a wide range of tiles. Tilers walking on rooves are less likely to break tiles held with such clips because the ratchet mechanism gives under the weight of the tiler so the clip does not form a rigid point about which the tile breaks.
