1 WORK INCLUDED
- (1) 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.
- (2) 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) 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) Architectural metal roof panel
- (6) '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) 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) 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: See the Standard for additional requirements.
