The drip edge on the lower portion of the gutter apron helps to direct water into the gutter instead of running behind it down the fascia board. The gutter apron also protects the gap between the fascia board and roof sheathing, preventing insects, animals, and water from entering the eaves and attic space. Any water that infiltrates the roof can be shed by the underlayment and then over the gutter apron. It is applied directly to the sheathing and beneath the underlayment.

The drip edge is the part of the metal component that has an outward projecting lower edge that is intended to divert dripping water away from other building materials such as wood siding, fascia boards, or masonry.
