A reinforced roofing membrane extends up and over the concrete tilt-up wall, supported by a layer of rigid insulation above a metal roof deck. A metal roof joist supports the deck assembly from below. The membrane must be creased at angle changes to limit bridging to a maximum of three-quarters of an inch. A coping cap finishes the top of the wall parapet.
