Benefits of technology

The present disclosure introduces different versions of a universal drip edge that can successfully prevent water runoff from roofs, regardless of the roof pitch. Additionally, it provides drip edge that can be reliably installed on roofs with adequate space for a fascia board, prior to attaching it. The drip edge also facilitates water coalescing, reducing scattering or splashing of roof runoff. In some cases, the drip edge has a varying thickness that enhances its stability, installation ease, and long-term performance just after installation. Overall, the patent helps to create a stronger and more robust drip edge for roof protection.

Problems solved by technology

The effectiveness of a drip edge may also be affected by the pitch of the roof.
Drip edges designed for flat roofs do not function properly when installed on a high pitch roof and vice versa.

Embodiment Construction

[0048]Although the present disclosure is described with reference to specific examples, it will be appreciated by those skilled in the art that the present disclosure may be embodied in many other forms. The embodiments discussed herein are merely illustrative and do not limit the scope of the present disclosure.

[0049]In the description which follows, like parts may be marked throughout the specification and drawings with the same or similar reference numerals. The drawing figures are not necessarily to scale and certain features may be shown exaggerated in scale or in somewhat generalized or schematic form in the interest of clarity and conciseness.

[0050]Generally described, this disclosure describes improved roof drip edges providing a variety of possible advantages over existing flashing systems. As will be described with reference to the figures, in some embodiments the drip edges described herein are advantageously configured to be installed by roofers so as to reliably provide...

Abstract

A structurally robust roof drip edge system including a tail and an outer section contiguous with the tail. The tail includes a locally thin section nailable to a roof substrate. The outer section includes a bridging member connecting an inner footing and an outer footing. The outer footing includes a drip edge profile 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 behind the drip edge profile. The drip edge may be bendable to a user-selectable angle between the tail and the outer section to accommodate a range of roof pitches.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 62 / 471,255, filed Mar. 14, 2017, entitled “DRIP EDGE,” which is hereby incorporated by reference in its entirety and for all purposes.BACKGROUNDField[0002]The present disclosure generally relates to weather resistant barrier systems, and more specifically to drip edge systems and methods.Description of the Related Art[0003]A drip edge can be installed at roof edges to guide water runoff away from fascia boards along roof linings and / or otherwise improve water management properties of the roof. The drip edge is typically a sheet of elongate metal bent across its length. The upper portion of the drip edge is inserted under the first course of roof shingles and attached to the roof while the lower portion extends downwardly from the edge of the roof to protect the fascia from roof runoff Because the fascia boards are often installed after roofing is completed, drip ...
