Membrane securement at 12" (304.80 mm) out from penetration and 12" o.c. (304.80 mm) required for Mechanically Attached Roof Systems. This can be accomplished with seam plates and fasteners overlaid with either TPO Cover Tape, a target patch of TPO field membrane for the boot flange to be welded to, or with 6" (152.40 mm) TPO Reinforced Flashing. When installation of the pipe boot would overlap a field seam, install a minimum 24" x 24" (609.60 mm x 609.60 mm) target patch centered on the penetration before installing the pipe boot. Membrane securement may also be installed close to the penetration and flashed with the pipe boot as shown here.

When running gas line supports on a Mechanically Attached Roof System, caremust be taken to run the supports on the lines of membrane securement in order to prevent movement caused by sheet flutter. The support area may be isolated from the main portion of the roof by installing a row of membrane securement on each side of the supports and then stripping them in with TPO Cover Tape installed to GenFlex specification.
