A turbulence-creating device is mounted to the roof, such that high winds flowing across the roof are caused to become turbulent, thereby interfering with the laminar flow and lift which would otherwise be created. The turbulence-creating devices comprise generally V-shaped or curved spoilers, many of which are pivotally mounted to a vertical mast attached to the roof such that the spoilers face in the direction of the oncoming wind and are shaped to disturb the laminar flow, thereby preventing lift from being generated. In some embodiments, fixed omnidirectional spoilers with curved sides are provided.
