A. If ≤3%, it is determined whether the roof is subject to vibrations: When the roof slope is less than 3%, the roofing material should be laid parallel to the ridge； When the roof slope is between 3% and 15%, the roofing membrane can be installed parallel or perpendicular to the ridge ； Roof ridge installation: Polymer-modified asphalt waterproofing membranes and synthetic polymer waterproofing membranes can be installed parallel or perpendicular to the roof ridge. The upper and lower layers of membranes should not be installed perpendicular to each other.
