Drip edge flashing is a metal strip installed along the edges of a roof to direct water away from the fascia and into the gutter system, preventing moisture damage. It features a slight outward bend (kickout) that helps guide water off the roof edge, reducing the risk of leaks, rot, and erosion. Made from galvanized steel, drip edge flashing enhances the longevity of the roofing system by protecting the roof deck, soffit, and underlying structure from water infiltration. It is essential for maintaining proper drainage and improving overall roof performance.
