Disclosed herein are various waterproof membranes that may be applied to a sill surface of an opening in a building structure to waterproof that surface as well as direct water that penetrates through the opening out of the structure. Generally, a flexible waterproof membrane is adhesively applied to the sill surface for purposes of waterproofing that surface. In one arrangement, the membrane includes a conformable adhesive flap that extends beyond the front edge of the sill surface and which is flexible to allow stretching and adhering the flap to a surface that is transverse (e.g., vertical) to the remainder of the membrane. The membrane also includes a non-adhesive flap that may be disposed over the adhesive flap once it is adhered in a desired orientation. The non-adhesive flap provides a durable surface for the adhesive flap once it is stretched and adhered in place.
