=== WORK INCLUDED ===
;(1) [[ASM Roof Systems Standard#ASMVALLEYMEM |'''Valley protection membrane''']]: Accepted self-adhered modified bituminous eave protection membrane. 
;(2) [[ASM Roof Systems Standard#ASMVALLEYPAN |'''Valley Metal Panel''']]: Preformed with centre rib.
;(3) [[ASM Roof Systems Standard#ASMCLIP|'''Metal panel clip''']]: Installed to metal roof panel manufacturer's printed instructions. 
;(4) [[ASM Roof Systems Standard#ASMVALOVERLAP |'''Valley panel overlap''']]: Overlaps minimum 200 mm (8") sealed with two rows of acceptable sealant or butyl tape, and secured with drag load fasteners.

;(6) [[ASM Roof Systems Standard#ASMUNDERLAYMENT|'''Underlayment''']]: The type of underlay required is determined by roof slope. 
;(7) [[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.
