1 WORK INCLUDED

(1) Deck overlay
Required for continuous support of the underlayment when the deck is not suitable.
(2) Underlayment (lower)
The type of underlay required is determined by roof slope.
(3) Wood blocking
(4) Insulation
Tapered to support gutter membrane, which is tied into underlayment, to ensure any water intrusion into roof system drains into gutter.
(5) Gutter Membrane
(6) Underlayment (upper)
(7) Upper insulation
Tapered at lower edge to conform to lower insulation slope. All flat panels must be offset and stagger layers 300 mm (12").
(8) Vapour-permeable separation membrane
Installed over insulation and required on all insulated Architectural Sheet Metal Roof Systems. The material must be located between the insulation and metal panels/ventilation material (see 8.1.2 Design)).
(9) Ventilation beneath panels
Recommended over asphaltic underlays and / or as required in this Standard (see 8.1.2 Design).
(10) Bearing plate
Only thermally non-conductive clips or bars passing through the insulation assembly, or mechanically fastened bearing plates, may be used to secure and support insulation panels, or provide support for panel clips.
(11) Architectural metal panel clip
(12) Architectural metal roof panel
Lower, installed prior to the pipe flashing, cut hole large enough to allow for movement. Extend 400 mm (16") upslope beyond the pipe.
(13) Mastic (2-ply SBS) or Sealant (Single plies)
Drain flange must be embedded in a membrane-compatible mastic and secured to the gutter structure.
(14) Drain Body
Mechanically secured through flange (for all drain types, see Part 11 DRAINS and PENETRATIONS in the relevant membrane standard in this Manual).
(15) Strainer
(16) Gutter Membrane
Refer to the relevant membrane standard for application requirements (SBS, EPDM, TPO or PVC).
(17) Parapet cap flashing

2 RELATED WORK BY OTHERS
