ABSTRACT:
The present invention provides a gutter screen attachment and a ridged filter assembly for minimizing water film runoff and debris collection adjacent a screened gutter. The screen attachment comprises a superior breaker edge, an inferior breaker edge, and a screen-receiving region. The superior breaker edge extends upwardly opposite the inferior breaker edge and is designed to break the water tension of a water film formed upon the gutter screen. The ridged filter assembly comprises a filter support grid, a filter screen and a ridge-forming member sandwiched between the filter support grid and the filter screen. The filter screen is form fit to the underlying structures and the ridge-forming member thus forms a water tension straining ridge upon the filter screen. The superior breaker edge and the filter screen ridge function to allow water to permeate through the gutter screen.
