 ;(8) [[EPDM Roof Systems Standard#PART_10|<big>Membrane Flashing</big>]]:
 :May be run continuously up the vertical substrate from the field or installed as separate flashing (see membrane manufacturer requirements).  Membrane shall be carried up the vertical substrate at least 203.2 mm (8”) above the ''finished roof system surface'', plus at least 76.2 mm (3”) for wall control layer overlap. In regions where heavy snow accumulation is possible, or to accommodate future roof membrane replacement, membrane should be carried at least 304.8 mm (12”) up the vertical substrate.

-:Where the ''wall'' is insulated on the exterior side of the structure, ''continuity'' of air and vapour controls must be protected from future damage during roof replacement.  This can be done by securing a suitable membrane receiver panel against the insulation.  The panel must be permanently affixed to the structure through the insulation.  During replacement of the roof membrane, membrane flashing may be removed from the receiver panel without disturbing the insulation and control layers.  In this way, material waste is also reduced.
+:All membranes applied to a vertical surface must be mechanically fastened.  Fastener illustrated, together with sealant applied to upper membrane edge.
