=== 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.
 
;(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.
 
;(3) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMCLIP|'''Metal Panel Clip''']]: Installed to metal roof panel manufacturer's printed instructions.
 
;(4) Bearing plate: Used to support clips and distribute dead and live loads when direct contact with a solid substrate is not possible.
 
;(5) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMPANEL |'''Architectural metal roof panel''']]
 
;(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.
 
;(7) Perforated ventilation metal: Mechanically fastened to wall and 'Z'-closure.  The outer edge serves as a hook for the roof-wall metal flashing.
 
;(8) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMSHEETMETAL |'''Sheet Metal Flashing''']]: Hooked to perforated ventilation metal 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.
 
;(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.

;(B) '''Wall control layers''': must be positively lapped with roof materials and flashings, to maintain continuity across systems.
 
;(C) '''Wall cladding''':
