Asphalt application shall result in approximately 25 pounds of asphalt ( 25% on a total job average basis) per roof square between each ply. 2. Unroll roofing membrane sheets and allow them to relax for minimum time period required by manufacturer. 3. Install specified membrane as starter strips at all edges, perimeters, transitions, around equipment curbs, and penetrations, and drains, a minimum of 18 width from the top of the cant strip or from the edge on to the roof in specified ply adhesive. B. Laps: Accurately align roofing membrane sheets, without stretching, and maintain uniform side and end laps. Stagger end laps. Completely bond and seal laps, leaving no voids. 1. Repair tears and voids in laps and lapped seams not completely sealed. 2. Apply roofing granules to cover exuded bead at laps while bead is hot. C. Install roofing membrane sheets so side and end laps shed water. 3.6 FLASHING AND STRIPPING INSTALLATION A.
