=== WORK INCLUDED ===
;(1) [[RoofStar Guarantee Standards for EPDM Membrane Systems#EPDMDECKWALLOVERLAY|'''Supporting Deck Overlay''']]: Recommended over steel decks, to provide continuous support for membrane control layers (this fulfills the requirement for continuity, ''British Columbia Building Code'', Div. B, '''5.4.1.2''' ('''3''')).
;(2) [[RoofStar Guarantee Standards for EPDM Membrane Systems#EPDMAIRVAPOUR|'''Air or Vapour Controls''']]: Self-adhering membrane (typical).
;(3) [[RoofStar Guarantee Standards for EPDM Membrane Systems#EPDMAIRVAPOURAPPLICATION|'''Metal Support''']]: For fully or intermittently unsupported side or end laps.  Use pre-finished galvanized steel (min. 24 Ga.), fabricated at least 100 mm (4”) wider than membrane overlaps, and secured with compatible flat-head fasteners (two fasteners per flute, or as otherwise specified).
;(4) [[RoofStar Guarantee Standards for EPDM Membrane Systems#EPDMAIRVAPOURAPPLICATION|'''Long edges''']]:Centre membrane runs along top flutes of steel deck (applicable when no deck overlay is specified and installed).
;(5) [[RoofStar Guarantee Standards for EPDM Membrane Systems#EPDMAIRVAPOURAPPLICATION| '''End laps''']]:Overlap the roll ends at least 100 mm (4”), or as specified by the membrane manufacturer (whichever is greater).  End laps must be fully supported by the roof deck or a metal support.
;(6) [[RoofStar Guarantee Standards for EPDM Membrane Systems#EPDMAIRVAPOURAPPLICATION| '''Side laps''']]:Overlap membrane side laps at least 50 mm (2”), or as specified by the membrane manufacturer (whichever is greater).  Side laps must be fully supported by the roof deck or a metal support.
