<p>1. Guttering for a roofing section covered with hollow tiles arranged in a succession of alternate rows (12, 14, 212, 214) of concave tiles and of covering tiles, forming a regular and repetitive pattern which determines a wave length, characterised in that it comprises an entirely flat bottom (21, 221) between a longitudinal downstream wall (24, 224) and a longitudinal upstream wall (22, 222) whose height enables the placing, without discontinuity, of a row of covering tiles on top of the guttering, and, joined to the longitudinal downstream wall, a corrugated strip (26, 226) adapted to cover the concave tiles and to be covered by the covering tiles.</p> |
