Flashing is layered protection. So what is flashing? It's a thin layer of waterproof material that keeps water from getting into places it doesn't belong. (Caulk is fine for filling small gaps around windows and doors, but it shouldn't be confused with flashing.)
Flashing squares are inserted between each row of roofing material. Flashing can also be used as a strip that runs around the dormer and under the roofing material. Unlike other windows in your home, the flashing is also extended into a front apron, which overlaps the roof material. As dormer size and window style vary from house to house, the details can be different for your house.
