A flanged counter flashing unit, flashing system and method is described for weather proofing the juncture of a brick wall overlying a vertical parapet wall and the edge of a sloped roof. The one-piece counter flashing unit of the flashing system has a vertical slit into which is securely fitted the low upstanding side of a J-Channel flashing positioned at the juncture and the vertical leaf member of an L-shaped roof flashing that is flush with the outer face of the upstanding low side of the J-Channel flashing, including a flange section of the counter flashing unit that extends laterally from the top edge of the counter flashing apron and partially over the J-Channel and an apron adapted for overlying the vertical leaf member of the L-shaped flashing. The J-Channel flashing, L-shaped flashing and flanged counter flashing are included in the flashing system of the present invention. According to the method of the present invention, when the flashing system is positioned at the juncture, the brick wall is constructed from within the J-channel so that the counter flashing flange is included in the brick wall. This method eliminates the need for a separate method step of attaching counter flashing to the brick wall at an angle to the horizontal plane of the brick wall after its construction by means of a gouge cut across the brick wall for that purpose.
