1 WORK INCLUDED

(1) Deck overlay: Required over some deck surface to provide a solid or continuous substrate for roof system materials. Here, a deck overlay is provided to support a continuous AVB layer.
(2) Underlayment: Applicable for all Architectural Sheet Metal systems. For slopes less than 1:3, the entire roof slope must be covered with a self-adhered underlayment.
(3) Insulation: Installed with offset side and end joints.
(4) 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 8.1.2 Design).
(5) 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.
(6) Metal Panel Clip: Installed to metal roof panel manufacturer's printed instructions.
(7) Bearing plate: Used to support clips and distribute dead and live loads when direct contact with a solid substrate is not possible.
(8) Architectural metal roof panel
(9) 'Z'-Closure: Set in acceptable sealant and secured with compatible, non-corrosive, flat head fasteners.
(10) 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.
(11) Metal Counter Flashing: Must extend behind wall system and wall control layers. Stucco stops are not considered to be a counter flashing.

2 RELATED WORK BY OTHERS

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

NOTE: Refer to RoofStar Guarantee Standards for additional requirements.
