Notice to Reader
Images used in a Construction Detail are representative and not intended in their representation of an assembly to be prescriptive. Nor are they necessarily drawn to scale. Rather, they are provided to visually convey the Standards, Guiding Principles and Recommendations of the RoofStar Guarantee Standards for a Waterproofing or Water-shedding System. Actual design with respect to dimensions, the selection of materials and their application remains the responsibility of the Design Authority. The full text of applicable RoofStar Guarantee Standards may be read by using the blue hyperlinks

1 WORK INCLUDED

(1) Membranes: Membranes must be installed to RoofStar Guarantee Standards and the manufacturer's printed instructions (NOTE: Fasteners shall be installed 4” or more above the maximum water line, and gutters must include a scupper overflow drain.). Also refer to 12.2 Built-in Gutters in the RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems.
(2) Adhesion: Membranes must be fully adhered, where exposed, and mechanically fastened at terminations 300 mm (12") o/c
(3) Height: The minimum vertical sealed height above the maximum water level is 150 mm (6"). The membrane run up the slope will vary with roof pitch. Increase height in heavy snow regions. Built-in gutter membranes can be extended to act as Ice and Water Protection. Underlay or eave protection membrane must overlap built-in gutter membrane by a minimum of 200 mm (8") and be installed in shingle fashion (not shown for clarity).
(4) Metal cap flashing

2 RELATED WORK BY OTHERS

(A) Acceptable Deck
(B) Dimension: Dimensions of parapets, cants and water loading of gutters are variable and should be determined by design authority

NOTE: Refer to RoofStar Guarantee Standards for additional requirements.

 === WORK INCLUDED ===
-;(1) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMUNDERLAYMENT|'''Underlayment''']]: The type of underlay required is determined by roof slope.
+;(1) '''Membranes''': Membranes must be installed to '''''RoofStar Guarantee Standards''''' and the manufacturer's printed instructions ({{hilite | NOTE: Fasteners shall be installed 4” or more above the maximum water line, and gutters must include a scupper overflow drain. || 2017-April-22 }}).  Also refer to [http://rpm.rcabc.org/index.php?title=RoofStar_Guarantee_Standards_for_Architectural_Sheet_Metal_(ASM)_Systems#Built-in_Gutters '''12.2 Built-in Gutters'''] in the '''''RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems'''''.
-;(2) [[RoofStar Guarantee Standards for ASM Roof Assemblies#ASMINSULALIGNMENT|'''Insulation''']]: Offset and stagger layers 300 mm (12").
+;(2) '''Adhesion''': Membranes must be fully adhered, where exposed, and mechanically fastened at terminations 300 mm (12") o/c
-;(3) [[RoofStar Guarantee Standards for ASM Roof Assemblies#ASMSEP-VENT|'''Separation layer''']]: Vapour-permeable layer over insulation, required on all insulated Architectural Sheet Metal Roof Systems.  The material must be located between the insulation and metal panels (see [http://rpm.rcabc.org/index.php?title=RoofStar_Guarantee_Standards_for_Architectural_Sheet_Metal_(ASM)_Systems#Design_5 '''8.1.2 Design''']).
+;(3) '''Height''': The minimum vertical sealed height above the maximum water level is 150 mm (6"). The membrane run up the slope will vary with roof pitch. Increase height in heavy snow regions.  Built-in gutter membranes can be extended to act as [http://rpm.rcabc.org/index.php?title=RoofStar_Guarantee_Standards_for_Architectural_Sheet_Metal_(ASM)_Systems#Eave_and_Valley_Protection_2  '''Ice and Water Protection'''].

-;(4) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMSLIP|'''Ventilation layer''']]: Recommended over asphaltic underlays and / or as required in this Standard (see [http://rpm.rcabc.org/index.php?title=RoofStar_Guarantee_Standards_for_Architectural_Sheet_Metal_(ASM)_Systems#Design_5 '''8.1.2 Design''']).
+;(4) Metal cap flashing
-;(5) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMINSULLAYERING|'''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.
-;(6) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMCLIP |'''Architectural metal panel clip''']]
-;(7) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMPANEL |'''Architectural metal roof panel (lower)''']]: Lower, installed prior to the pipe flashing, cut hole large enough to allow for movement. Extend 400 mm (16") upslope beyond the pipe.
-;(8) '''Spaced Cleat''': Cleats, set in accepted caulking, spaced 50 mm (2") and fastened with compatible non-corrosive flat head screws.
-;(9) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMSEALANT |'''Sealant''']]
-;(10) Split panel
