Roof flashing is a thin material, usually galvanized steel, that professional roofers use to direct water away from critical areas of the roof, wherever the roof plane meets a vertical surface like a wall or a dormer. Flashing is installed to surround roof features, such as vents, chimneys and skylights. Water should run down the side of the flashing and be directed to the shingles instead of finding its way into the roof deck.
Flashing is made from different materials, including: metal, paper, plastic and liquid adhesives. Drip edge flashing is a long strip of angled metal. This trip is attached to the edges of a roof and directs rainwater away from the structure via the gutters. Drip edge flashing protects decking, wood trim and wood soffits.
