A roof water dispersal system includes a plurality of longitudinally extending dispersal elements mounted near the edge of a roof structure for receiving and dispersing streams of roof run-off water. The elements are spaced apart from each other and assembled into a unit mounted to receive the streams of run-off roof water. The individual elements within the assembly can vary in shape, thickness, or material to provide an optimum balance between dispersal efficiency and strength of the overall assembly. A weir is mountable near the edge of the roof and aligned with cross members of the rain dispersal assembly to divert the roof run-off water streams from impacting on regions of the assembly at which the dispersal elements intersect with cross members to prevent undesirable deflection or collection of run-off water at these regions. The systems of the present invention are designed to provide optimum dispersion characteristics at regions of the assembly intended to receive the major portion of roof run-off water, to divert streams of water away from regions of the assembly having less than optimum dispersal characteristics, or to modify components of the system such as supporting brackets and cross members to minimize the adverse effect of such components on the dispersion characteristic of the system. |
