  • Such a roof has a rainwater collection system captured by the blades in the closed position of the roof.
  • the recovery system comprises, for example, gutters defining an open channel above which extend the end edges of the steerable blades. This open channel communicates with an exhaust duct extending inside a pole of the bearing structure of the blades.
  • all the adjustable blades are inclined in the same direction to ensure the flow of water along the same end edge of the blades extending above a gutter beam. Under certain conditions of use, a small portion of the water discharged by the blades is not recovered by the gutter beam but falls outside such a beam causing inconvenience to the users of such a roof.
