The panel may include an aperture 50 for accommodating a roof component, for example a roof light. The deflectors may be arranged below the aperture and may be in the form of ridges projecting from an upper surface of the panel. The panel may comprise one or more flow splitting arrangements constituted by a group of deflectors. The panel may further include at least one flow path divider 47 arranged below the or each flow splitting arrangement. The panel may be formed from a plurality of panel sections 26a, 26b of flexible material and may be textured to reduce the surface tension of water running down the panel.</p> |
