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. It helps prevent water infiltration, protecting the roof deck, soffit, and underlying structure from moisture damage. Made from galvanized steel, drip edge flashing features a small outward bend (kickout) that ensures water drips away from the roof edge rather than running down the fascia. It is essential for extending the lifespan of a roofing system by reducing the risk of rot, mold, and water-related deterioration.
