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.
Claims17
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.

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.
