Extruded roof tile and method of manufacturing an extruded roof tile
A roof tile 1, having a pan 2/5 and a roll 3/6 each extending along the length of the tile, the roll extending from a side of the pan, at least one channel 11-14 in the top surface of the tile, extending laterally across the tile in the width direction of the tile through the pan and terminating at a side of the roll before reaching the top of the roll. The lower in use edge of the channel may have a chamfered curved leading into the channel and the upper side may have a raided step. Also claimed is a method of manufacturer by continuous extrusion using a machine (30) with simultaneously moving cutting and channel forming blades (37/38 Figs. 6-7) which may be timed to form the chamfer and raised portion when cutting channels. The lower side may have anti-capillary grooves (28, 29 Fig. 5). The channels are only located in the pans, and do not extend onto rolls/side overlapping interlocks to prevent capillary action laterally. The tiles may be cementitious e.g. concrete.
