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

 === WORK INCLUDED ===
-;(1) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMUNDERLAYMENT|'''Underlayment''']]: Applicable for all Architectural Sheet Metal systems.  For slopes less than 1:3, the entire roof slope must be covered with a <u>self-adhered</u> underlayment.
+;(1) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMVALLEYMEM |'''Valley Protection Membrane''']]: Accepted self-adhered modified bituminous eave protection membrane.
-;(2) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMSEP-VENT|'''Ventilation material''']]: A ventilation space is required on slopes less than 1:3; entangled mesh (shown) may be used as void fill.  The ventilation space facilitates drying as condensation forms on the underside of the metal panels.
+;(2) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMVALLEYPAN |'''Valley flashing''']]
-;(3) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMCLIP|'''Metal Panel Clip''']]: Installed to metal roof panel manufacturer's printed instructions.
+;(3) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMFASTENING |'''Fastening''']]: Metal valley panels to be secured with compatible, non-corrosive, flat head fasteners 200 mm (8") o/c. Metal roof panel to metal valley panel overlap must be a minimum of 125 mm (5"). See '''10.3.5.2.2''' ('''5''').
-;(4) Bearing plate: Used to support clips and distribute dead and live loads when direct contact with a solid substrate is not possible, or when entangled mesh is used within the ventilation space.
+;(4) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMVALOVERLAP |'''Valley panel overlap''']]: Set in two continuous rows of accepted caulking or sealant tape.
-;(5) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMPANEL |'''Architectural metal roof panel''']]
+;(5) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMICE|'''Membrane flashing''']]: Accepted self-adhered modified bituminous eave protection membrane.
-;(6) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMZ |''''Z'-Closure''']]: Set in acceptable sealant and secured with compatible, non-corrosive, flat head fasteners.
+;(6) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMUNDERLAYMENT|'''Underlayment''']]: The type of underlay required is determined by roof slope.
-;(7) Ventilation screen: secured to the wall and to Z-girts to provide insect-resistant air flow around the roof-wall connection.  Girts must be set in acceptable sealant and secured with compatible, non-corrosive, flat head fasteners.
+;(7) [[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''']).
-;(8) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMSHEETMETAL |'''Sheet Metal Flashing''']]: Hooked to 'Z'-Closure and fastened to wall with non-corrosive, flat head fasteners 300 mm (12") o/c or preformed foam closures set in acceptable sealant with high domed gasketed cladding type screws at each standing rib.
+;(8) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMPANEL |'''Architectural Metal Roof Panel''']]
-;(9) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMCOUNTER |'''Metal Counter Flashing''']]: Must extend behind wall system and wall control layers. Stucco stops are not considered to be a counter flashing.
