=== WORK INCLUDED ===
;(1) [[ASM Roof Systems Standard#ASMUNDERLAYMENT|'''Underlayment''']]: The type of underlay required is determined by roof slope.
;(2) Ridge girts: May be required by engineer for panel drag load fasteners.  Secured using compatible non-corrosive fasteners.
;(3) [[ASM Roof Systems Standard#ASMINSULALIGNMENT|'''Insulation''']]: Offset and stagger layers 300 mm (12").
;(4) [[ASM Roof Systems Standard#ASMSEP-VENT|'''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 [http://rpm.rcabc.org/index.php?title=RoofStar_Guarantee_Standards_for_Architectural_Sheet_Metal_(ASM)_Systems#Design_5 '''8.1.2 Design''']).
;(5) [[ASM Roof Systems Standard#ASMSLIP|'''Ventilation layer''']]: 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.
;(6) [[ASM Roof Systems Standard#ASMCLOSURE |'''Architectural metal roof panel''']]: Top end of panels must be "bread-panned".  Clips are not illustrated.
;(7) [[ASM Roof Systems Standard#ASMDRAG |'''Drag-load fasteners''']]: Compatible non-corrosive fasteners.
;(8) [[ASM Roof Systems Standard#ASMZ | '''Foam closures''']]: may be used to close ridge when cap flashing is mechanically attached to the panels ribs (see '''10.3.5.3''' ('''1''')('''2''')).
;(9) [[ASM Roof Systems Standard#ASMZ | '''Ridge cap flashing''']]
;(10) [[ASM Roof Systems Standard#ASMZ | '''Fasteners''']]: See '''10.3.5.3''' ('''1''')('''2''').
