Abstract
A self-adhesive flashing for integrating a flanged fenestration unit installed in a rough opening in a wall with a water resistive barrier where the flashing includes an elongated substrate having a pressure-sensitive adhesive layer adhered to at least one side of the substrate along a lateral edge of the substrate and methods for applying the flashing.
