Drip Edge

Definition - What does Drip Edge mean?

A drip edge is a metal protrusion located at the corner of a roof used to direct and strip away rainwater and moisture accumulation. A drip edge is vital in preventing roof and surface corrosion since the presence of stagnant water can facilitate several forms of corrosion.

It is a metal flashing, or other overhanging component, with an outward projecting lower edge, intended to control the direction of dripping water and help protect underlying building components. A drip edge also can be used to break the continuity of contact between the roof perimeter and wall components to help prevent capillary action.
