The invention relates to a wind turbine device for a roof, comprising a rotor with a horizontal rotational axis substantially at a right angle relative to the wind direction, and arranged in a frame (2) to be placed on a rooftop, the frame (2) including, on each of the two sides of the roof, an assembly of deflectors (3) capable of concentrating the airflows toward the rotor. Each of the deflector (3) assemblies includes four walls, i.e. two side walls (33), an upper wall (34) and a lower wall (32), which form a tunnel (3) that tapers from the outer end (30) thereof toward the end (31) thereof, wherein the frame (2) and the deflector (3) assemblies comprise means (36, 37) designed for adapting to the slopes of the roof (1) while maintaining the same ratio between the openings (30, 31) of the tunnels (3). |
