A roof vent assembly and roof flashing for facilitating a seal between an inclined roof surface having a longitudinal contoured profile and a upstanding vent member extending through said roof surface are disclosed. The roof flashing includes a base plate having respective aprons extending from opposing sides of the base plate, wherein the aprons have a contoured profile conforming to the longitudinal contoured profile of the inclined roof surface and an aperture centrally disposed in the base plate. The aperture is configured to encompass a periphery of the upstanding vent member when the base plate is mounted on the inclined roof surface and the contoured profiles of the aprons are superimposed on the longitudinal contoured profile of the inclined roof surface.

The roof flashing according to claim 2, wherein the aperture defines an ellipse having a transversely disposed minor axis and a longitudinally disposed major axis. 4. The roof flashing according to claim 3, wherein the minor axis has a length marginally greater than an outer diameter (OD) of the upstanding vent member and the major axis has a length (h) dependent on an angle of inclination (α) of the inclined roof surface and the outer circumference of the upstanding vent member, wherein length (h) equals OD/cosine(α). 5. The roof flashing according to claim 1, wherein the aperture is configured to encompass a periphery of an upstanding vent member having a square or rectangular cross-section. 6. The roof flashing according to claim 5, wherein the aperture defines a rectangle having a longitudinally disposed major axis and a transversely disposed minor transverse axis. 7. The roof flashing according to claim 6, wherein the minor axis has a length marginally greater than an outer transverse dimension of the upstanding vent member and the major axis has a length (h) dependent on an angle of inclination (α) of the inclined roof surface and the outer longitudinal dimension (D) of the upstanding vent member, wherein length (h) equals D/cosine(α). 8. The roof flashing according to claim 1, wherein the base plate is provided with a plurality of lugs depending from a periphery of the aperture configured, in use, to attach to the upstanding vent member. 9. The roof flashing according to claim 1, wherein the contoured profile of the aprons is selected from a group comprising corrugated profile, trapezoid corrugated profile, fluted profile, square fluted profile, and trapezoid fluted profile. 10. A roof vent assembly for use on an inclined roof surface having a longitudinal contoured profile comprising an upstanding vent member for extending through said roof surface, and a roof flashing according to claim 1. 11. The roof vent assembly according to claim 10, further comprising a cap member for preventing water ingress through an open upper end of the upstanding vent member. 12. The roof vent assembly according to claim 11, wherein the upstanding vent member is provided with a plurality of lugs configured, in use, to attach to the cap. 13. The roof vent assembly according to claim 12, wherein the plurality of lugs extend from an upper rim of the upstanding vent member. 14. The roof flashing according to claim 10, wherein the base plate is provided with a plurality of lugs depending from a periphery of the aperture. 15. The roof flashing according to claim 10, wherein the contoured profile of the aprons is selected from a group comprising corrugated profile, trapezoid corrugated profile, fluted profile, square fluted profile, and trapezoid fluted profile. 16. The roof vent assembly according to claim 10, wherein the upstanding vent member is provided with a plurality of ventilation holes in an upper portion thereof. 17. The roof vent assembly according to claim 10, wherein the aperture is configured to encompass a periphery of a cylindrical vent member. 18. The roof vent assembly according to claim 17, wherein the aperture defines an ellipse having a transversely disposed minor axis and a longitudinally disposed major axis. 19. The roof flashing according to claim 18, wherein the minor axis has a length marginally greater than an outer diameter of the upstanding vent member and the major axis has a length dependent on an angle of inclination of the inclined roof surface and the outer circumference of the upstanding vent member. 20. The roof flashing according to claim 10, wherein the aperture is configured to encompass a periphery of an upstanding vent member having a square or rectangular cross-section. 21. The roof flashing according to claim 20, wherein the aperture defines a rectangle having a longitudinally disposed major axis and a transversely disposed minor transverse axis. 22. The roof flashing according to claim 21, wherein the minor axis has a length marginally greater than an outer transverse dimension of the upstanding vent member and the major axis has a length dependent on an angle of inclination of the inclined roof surface and the outer longitudinal dimension of the upstanding vent member.
