1 WORK INCLUDED
- (1) Valley Protection Membrane
- Accepted self-adhered modified bituminous eave protection membrane.
- (2) Valley flashing
- (3) Fastening
- Metal valley panels to be secured with compatible, non-corrosive, flat head fasteners 200 mm (8") o/c. Metal roof panel to metal valley panel overlap must be a minimum of 125 mm (5"). See 10.3.5.2.2 (5).
- (4) Valley panel overlap
- Overlaps minimum 200 mm (8") sealed with two rows of acceptable sealant or butyl tape, and secured with drag load fasteners.
- (5) Membrane flashing
- Accepted self-adhered modified bituminous eave protection membrane.
- (6) Underlayment
- The type of underlay required is determined by roof slope.
- (7) 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.
- (8) Architectural metal roof panel
2 RELATED WORK BY OTHERS
- (A) Acceptable Deck
NOTE: See the Standard for additional requirements.
