Abstract

A roof flashing having a base and a flexible collar operatively connected thereto is configured to prevent water infiltration around an exhaust pipe extending through a roof. The base includes a flat plate having a connecting mechanism extending upwardly from the plate. The collar includes either a fixed-diameter opening or a multi-diameter opening thereto, wherein the opening is configured to receive and seal against a pipe extending from the roof to which the roof flashing is attached. The collar is fixedly attached to the connecting mechanism of the base.

First claim

What is claimed is:

1. A roof flashing comprising:
a base includes a plate having a top surface and a connecting mechanism extending at an angle from the top surface,
wherein the connecting mechanism defines a central aperture formed through the base and comprises a flange having an upper surface, the base further including a diverter extending from the top surface of the plate,
wherein the diverter surrounds at least a portion of the connecting mechanism and is spaced apart therefrom, and
wherein a plane extends from the top surface of the plate, the plane being perpendicular to the top surface of the plate, the upper surface of the flange being spaced from the top surface of the plate by a first distance along the plane, and an uppermost point of the diverter being spaced from the top surface of the plate by a second distance along the plane, wherein the second distance is greater than the first distance; and,
a flexible collar operatively connected to the connecting mechanism of the base, the flexible collar having an opening for receiving and sealing against a pipe.

2. The roof flashing of claim 1 , wherein the upper surface of the flange extends laterally around the central aperture in a closed loop path.

3. The roof flashing of claim 1 , wherein the connecting mechanism further includes a transition, wherein the transition extends at an angle from the top surface of the plate, and the flange is integrally formed with and extends at an angle from the transition.

4. The roof flashing of claim 3 , wherein the transition of the connecting mechanism laterally surrounds the upper surface of the flange in a closed loop path.

5. A roof flashing comprising:
a base includes a plate having a top surface and a connecting mechanism extending at an angle from the top surface,
wherein the connecting mechanism defines a central aperture formed through the base and comprises a flange having an upper surface that is substantially parallel to the top surface of the plate, the base further including a diverter extending from the top surface of the plate,
wherein the diverter surrounds at least a portion of the connecting mechanism and is spaced apart therefrom, and
wherein a plane extends from the top surface of the plate, the plane being perpendicular to the top surface of the plate, the upper surface of the flange being spaced from the top surface of the plate by a first distance along the plane, and an uppermost point of the diverter being spaced from the top surface of the plate by a second distance along the plane, wherein the second distance is greater than the first distance; and,
a flexible collar operatively connected to the connecting mechanism of the base, the flexible collar having an opening for receiving and sealing against a pipe.

6. The roof flashing of claim 5 , wherein the upper surface of the flange extends laterally around the central aperture in a closed loop path.

7. The roof flashing of claim 5 , wherein the connecting mechanism further includes a transition, wherein the transition extends at an angle from the top surface of the plate, and the flange is integrally formed with and extends at an angle from the transition.

8. The roof flashing of claim 7 , wherein the transition of the connecting mechanism laterally surrounds the upper surface of the flange in a closed loop path.

9. The roof flashing of claim 1 , wherein the connecting mechanism comprises a flange having an upper surface that is substantially parallel to the top surface of the plate.

10. The roof flashing of claim 1 , wherein the base is formed from aluminum, galvanized steel, copper, or hard plastic.

11. The roof flashing of claim 3 , wherein the flange includes a plurality of apertures formed therethrough.

12. The roof flashing of claim 1 , wherein the flexible collar is overmolded onto the connecting mechanism of the base.

13. The roof flashing of claim 1 , wherein the flange of the connecting mechanism defines the central aperture.

14. The roof flashing of claim 13 , wherein the central aperture that the flange defines is a teardrop-shaped central aperture.

15. The roof flashing of claim 1 , wherein the opening of the collar includes a fixed-diameter opening or a user-selectable multi-diameter opening.

16. The roof flashing of claim 1 , wherein the collar includes a connecting portion operatively connected to the connecting mechanism of the base, a sloped portion extending from the connecting portion, and a sealing portion extending from the sloped portion, the sealing portion defining an opening to the collar.

17. The roof flashing of claim 16 , wherein the sealing portion includes at least a first removable ring extending from an upper end of the sloped portion, the first removable ring being selectively detachable from the sloped portion to increase a diameter of an opening of the sealing portion.
