A flashing system configured to reduce moisture intrusion at an opening extending through an exterior treatment of a building structure. The flashing system includes at least one flashing piece having a main flashing portion and a sealing flange. The main flashing portion is configured to extend outward a distance from a periphery of the opening of the building structure to provide an effective moisture barrier and configured to be positioned against a wall having the opening defined therein. The sealing flange of the at least one flashing piece includes a top sealing flange, a bottom sealing flange, a first side sealing flange and a second side sealing flange each configured to extend outward from the main flashing portion and is configured to be positioned adjacent a peripheral-opening-structure at a respective top periphery, bottom periphery, first side periphery and second side periphery of the opening. The flashing system also includes a first top tab and a second top tab. The first top tab configured to extend laterally from the first end of the top sealing flange and configured to extend partially over the first side sealing flange. The second top tab is configured to extend laterally from a second end of the top sealing flange and configured to extend partially over the second side sealing flange. With this arrangement, the first top tab and the second top tab provide a mechanism to interconnect the top sealing flange to the first and second side sealing flanges such that the flashing system substantially reduces moisture intrusion at the opening extending through the exterior treatment of the building structure.
