ABSTRACT:
An elongated strip of extruded plastic or roll formed metal material includes a rear securing fifth plane that inserts beneath a roofing membrane of a building structure. The rear plane integrally connects to a forward extending perforated fourth plane by means of a u shaped channel, one of two u shaped channels, which additionally serve to receive and secure a lateral edge of a filtration membrane. The perforated fourth plane contains intrinsic and intersecting vertical water directing planes that extend above and beneath the surface of the fourth plane and which serve to support and contact an overlying insertable filtration membrane. The fourth plane connects to a forward extending third plane by means of a u shaped channel that serves to receive and secure a lateral edge of a filtration membrane. The third plane connects to a second plane by means of a downward extending u shaped channel. The second plane rests on the top front lip of a k-style gutter and is adjoined by a downward angled first plane that serves to disallow roof water runoff from contacting the front face of a k-style gutter. A combination of a filtration membrane configured for water permeability and debris repellency resting on vertical planes serves to break the forward flow of water, at points of contact between the vertical planes and filtration membrane, and also serves to further channel water downward through an underlying perforated plane into an underlying rain gutter. The filtration membrane is readily inserted into the u-shaped channels existing on the forward and rear edges of a perforated fourth plane.
