Flashing structure
View Patent ↗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.

4. A flashing structure according to claim 3 , wherein the first longitudinal edge of the channel floor of the second drainage channel is operatively connected to the second longitudinal edge of the channel floor of the first drainage channel via the first supporting lip.
5. A flashing structure according to claim 3 , wherein the second supporting lip is provided with a nailing flange.
6. A flashing structure according to claim 1 , wherein the flashing structure is provided with fastening means for fastening the flashing structure onto the roof surface.
7. A flashing structure for mounting onto a roof surface and used for receiving at least one shingle, the flashing structure comprising:
a first drainage channel extending longitudinally along the flashing structure, the first drainage channel comprising a channel floor having opposite first and second longitudinal edges, the first and second longitudinal edges of the first drainage channel being each provided with a bend;
a first supporting lip being operatively connected to the channel floor of the first drainage channel via the bend provided on the second longitudinal edge thereof;
a securing lip operatively connected to the channel floor of the first drainage channel via the bend provided on the first longitudinal edge thereof, the securing lip being positioned over the first drainage channel and extending along the same, a gap being defined between the securing lip and the supporting lip, said gap being shaped and sized for receiving said at least one shingle;
a second drainage channel extending longitudinally along the flashing structure, the second drainage channel comprising a channel floor having opposite first and second longitudinal edges, the first and second longitudinal edges of the second drainage channel being each provided with a bend, the second drainage channel being fluidly connected to the first drainage channel; and
a second supporting lip being operatively connected to the channel floor of the second drainage channel via the bend provided on the second longitudinal edge thereof, the second supporting lip being provided with a nailing flange.
8. A flashing structure according to claim 7 , wherein the securing lip is provided with an abutment flange projecting perpendicularly therefrom.
9. A flashing structure for mounting onto a roof surface and used for receiving at least one shingle, the flashing structure comprising:
a first drainage channel extending longitudinally along the flashing structure, the first drainage channel comprising a channel floor having opposite first and second longitudinal edges, the first and second longitudinal edges of the first drainage channel being each provided with a bend;
a first supporting lip being operatively connected to the channel floor of the first drainage channel via the bend provided on the second longitudinal edge thereof;
a second drainage channel extending longitudinally along the flashing structure, the second drainage channel comprising a channel floor having opposite first and second longitudinal edges, the first and second longitudinal edges of the second drainage channel being each provided with a bend, the bend provided on the second longitudinal edge of the channel floor of the second drainage channel being integral to the bend provided on the second longitudinal edge of the channel floor of the first drainage channel, the second drainage channel being fluidly connected to the first drainage channel; and
a securing lip operatively connected to the channel floor of the first drainage channel via the bend provided on the first longitudinal edge thereof, the securing lip being positioned over the first drainage channel and extending along the same, a gap being defined between the securing lip and the bend provided on the first longitudinal edge of the channel floor of the first drainage channel, said gap being shaped and sized for receiving said at least one shingle;
wherein the first supporting lip is positioned, shaped and sized for operatively pressing said at least one shingle against the securing lip, so as to minimize a given space thereinbetween.
10. A flashing structure according to claim 9 , wherein the securing lip is provided with an abutment flange projecting perpendicularly therefrom.
11. A flashing structure according to claim 1 , wherein the flashing structure is a valley flashing structure used for mounting onto a valley of a root surface and used for receiving at least one shingle, said valley flashing structure comprising:
a pair of first drainage channels extending longitudinally along the valley flashing structure;
a pair of securing lips, each of the securing lips being positioned over a corresponding first drainage channel and extending along the same, a gap being defined between each of the securing lips and sad corresponding first drainage channel, each of the gaps being shaped and sized for receiving at least one shingle; and
a pair of second drainage channels extending longitudinally along the valley flashing structure, each of the second drainage channels being fluidly connected to a corresponding first drainage channel.
