The answer to 'drip edge or drip edge' is that they are the same thing. Drip edge is a metal flashing that is installed along the edges of a roof to help direct water away from the fascia and prevent water damage. It is a crucial component of a properly installed roof system.
Drip edge helps protect the roof's edge from water damage by channeling water away from the fascia and preventing it from seeping behind the gutters. It also helps prevent shingle blow-off and water intrusion under the roofing materials. Drip edge is typically made of aluminum, galvanized steel, or copper and comes in a variety of colors to match the roof.
