The answer to 'drip edge or drip edge' is that they are the same thing. A drip edge is a metal flashing installed along the edges of a roof to prevent water from dripping directly down the fascia board. It helps direct water runoff away from the roof's edge and protects the underlying structure from water damage.
Drip edges are an essential component of a properly installed roof. They come in a variety of materials, including aluminum, galvanized steel, and copper, and are available in different shapes and sizes to fit different roof types. The drip edge is installed by nailing or screwing it into the roof deck, creating a barrier that guides water away from the building.
