Lap areas <br /> must be kept free of adhesive. <br /> E. Whenever possible,the entire roll of felt should be applied in a continuous manner. If rolls <br /> are allowed to set while partially rolled out,the membrane shall be cut and reset in a unifoim <br /> application of adhesive, lapping minimum of 12 inches back onto previously laid portion of <br /> roll. <br /> F. All side and end laps shall be heat fused. All laps shall be clean and free of dirt, debris and <br /> contaminants prior to welding. No open flames shall be used for heat fusing. <br /> G. A bead of molten bitumen shall be visible at all seams. The bead shall be a minimum of 3/8 <br /> inch in width but not greater than one inch width. <br /> H. No side or end laps shall occur within 18 inches of the center line of roof drains. <br /> 3.05 Granules <br /> A. After heat fusing laps and while bitumen is hot fully imbed ceramic roofing granules. <br /> Granules shall be applied to all areas of visible bitumen and shall be of sufficient coverage to <br /> provide a uniform appearance. No bitumen shall be visible. <br /> B. After bitumen has cooled all loose granules shall be swept from the roof and removed. <br /> 3.06 Baseflashing <br /> A. Membrane baseflashing shall be constructed over the top of the completed roof <br /> membrane and onto vertical surfaces using polymer modified materials. Flashing shall <br /> be applied by heat fusing. All wood surfaces shall be covered with a mechanically <br /> fastened base ply prior to application of flashing membrane. The base ply shall be <br /> adhered with flashing cement and fastened a minimum of nine inches on center. <br /> B. Flashing materials shall conform tightly to vertical and inclined surfaces. Bridging,sagging, <br /> or air pockets will not be accepted. All laps shall be heat fused. <br /> C. Unless otherwise shown on the drawings, extend flashing a minimum of eight inches above <br /> the finished roof level and a minimum of four inches onto the horizontal membrane surface. <br /> D.
