Abstract: An inside corner gutter piece for a roof gutter system having an angled outer wall of a center segment extending at a 45 degree angle to outer walls of two straight end segments, the outer wall of the center segment acting as a flow diverter for directing rain runoff from a roof valley into connected straight gutter sections, with a top and down turned edge acting to block a rainwater off-flow stream from flowing up and out of the outer wall of the inside corner gutter piece.

Abstract: An elongated strip of extruded plastic or roll formed metal material includes a rear securing plane that inserts beneath a roofing membrane of a building structure. The rear plane integrally connects to a reversed curved surface arranged longitudinally witch connects to a forward extending perforated second plane by means of a channel, one of two channels, which additionally serve to receive and secure a lateral edge of a filtration membrane. The perforated second plane contains intrinsic and intersecting vertical water directing planes that extend above and beneath the surface of the second plane and which serve to support and contact an overlying insertable filtration membrane. The second plane interconnects to a forward extending plane by means of a channel that serves to receive and secure a lateral edge of a filtration membrane. The plane connects to a second plane by means of a downward extending channel.

Abstract: A Extreme Flow Gutter Miter includes a miter with an extended front end to handle water flow from a roof valley under all conditions. The gutter valley handler accommodates the extreme water flow under all conditions of the roof valley and yet also provides a superior solution for water overflow in all instances of water flow from a roof valley.
