A flashing structure for mounting onto a roof surface and used for receiving shingles. The flashing structure includes a first drainage channel extending longitudinally along the flashing structure. The flashing structure also includes a securing lip positioned over the first drainage channel and extending along the same, a gap being defined between the securing lip and the first drainage channel, the gap being shaped and sized for receiving the shingles. The flashing structure also includes a second drainage channel extending longitudinally along the flashing structure, the second drainage channel being fluidly connected to the first drainage channel. These features can be adapted to various flashings used in the metal roofing industry, including, but not limited to gable-end flashings, end-wall flashings, and valley flashings, as well as other related flashing structures.
