Abstract

A customizable roof drip edge system includes an inner footing, an outer section, and a tail integrally formed with the inner footing and the outer section. The tail is nailable to a roof substrate. The outer section includes a bridging member connecting the tail to an outer footing. The bridging member and the outer footing are configured for directing the flow of water off of a roof. The inner footing is spaced from the outer footing by a suitable distance and configured to be placed against an eave as a positioning aid such that the drip edge can easily and reliably be installed with sufficient spacing for the installation of a fascia board after installation of the drip edge. The drip edge may be bendable to user-selectable angles between the tail and the inner footing and outer section to accommodate a range of roof pitches.

First claim

What is claimed is:

1. An integrally formed universal drip edge comprising:
a tail extending along a length of the drip edge, the tail comprising a lower layer and an upper layer contiguous with the lower layer at a bendable longitudinal tail joint extending along the length of the drip edge at an upper end of the tail;
an inner footing extending along the length of the drip edge and integrally formed with the lower layer at a lower end of the tail; and
an outer section extending along the length of the drip edge and comprising:
a bridging member having a proximal end integrally formed with the upper layer at the lower end of the tail to define a roof angle; and
an outer footing parallel to the inner footing and integrally formed with a distal end of the bridging member opposite the proximal end;

wherein the roof angle is selectable by bending at least one of the inner footing and the bridging member relative to the tail;
wherein the inner footing comprises an inner surface proximate the lower layer, the inner surface configured to be placed against an end surface of a roof substrate to define a drip edge installation position; and
wherein the bridging member, the inner footing, and the outer footing define a downward-facing channel configured to receive and partially surround a fascia board.

2. The drip edge of claim 1 , wherein the bridging member meets the upper layer of the tail along a bendable upper angled joint.

3. The drip edge of claim 1 , wherein the inner footing meets the lower layer of the tail along a bendable lower angled joint.

4. The drip edge of claim 1 , wherein a lower angle between the inner footing and the lower layer of the tail is adjustable, and wherein an upper angle between the bridging member and the upper layer of the tail is adjustable independently of the lower angle.

5. The drip edge of claim 1 , wherein the bridging member and the upper layer of the tail define an upper angled joint having an angle of between 135 degrees and 180 degrees.

6. The drip edge of claim 1 , wherein the tail is configured to receive one or more mechanical fasteners for securing the drip edge to a roof substrate.

7. The drip edge of claim 1 , wherein the outer footing comprises a top end integrally formed with the bridging member and a bottom end opposite the top end, the bottom end comprising a lip disposed at an angle relative to the outer footing.

8. The drip edge of claim 7 , wherein the bottom end comprises a double layer terminating in a joint.

9. The drip edge of claim 1 , wherein the inner footing, the outer section, and the tail comprise aluminum.

10. The drip edge of claim 9 , wherein the outer section and the tail are manufactured by bending to form an integral drip edge system.

11. The drip edge of claim 9 , wherein the aluminum is sheet aluminum having a thickness not greater than 21 gauge and not less than 26 gauge.

12. The drip edge of claim 1 , wherein the outer footing is configured to accommodate and direct a flow of water received from a roof.

13. The drip edge of claim 1 , wherein the c-shaped channel is sized and shaped to allow the fascia board to be installed to the roof substrate after the drip edge is installed to the roof substrate.
