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.
