The cover assembly ( 14 ) includes a one piece screen ( 20 ) and a plurality of fluted perforations ( 22 ) formed in the screen ( 20 ). The fluted perforations ( 22 ) are each particularly configured to draw water through the screen ( 20 ) without allowing undesired debris through the screen ( 20 ) and each includes a channel ( 40 ) recessed into the screen ( 20 ) and a corresponding hole ( 42 ) defined in the downhill end of the channel ( 40 ). A valley segment ( 210 ) of the system is also disclosed and includes a plurality of bull-nose ledges ( 212, 214, 216, 218 and 220 ), each guarding a plurality of fluted perforations ( 222 ) along the valley of a roof.
