ABSTRACT:
A roof gutter attachment which overlies a roof gutter to prevent gutter and/or downspout clogging due to the undue or unwanted accumulation of debris. The arrangement presents a pattern of downwardly inclined parallel steps presenting grooves oriented in the path of liquid flow increasing liquid area expanse and the passage of smaller sized debris by reason of liquid adhesion. Linear ridges are defined between each of the grooves, such serving for ready sliding movement of larger sized debris over the gutter and into a receiving area therebelow. Air pressure differential creates a self-cleaning attachment when wind moves across the attachment.
