1 WORK INCLUDED
- (1) Separation membrane
- Separates the deck and the metal edge flashing.
- (2) Hook securement strip
- In this particular rake edge configuration, a similar strip is installed along the rake to secure the flush rake-edge flashing.
- (3) Continuous eave metal flashing
- (4) Eave protection
- One ply of self-adhered modified bituminous underlayment material. Lap 50 mm (2") minimum on sides and 100 mm (4") minimum on ends.
- (5) 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.
- (6) Ventilation beneath panels
- 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.
- (7) Metal panel clip
- Installed in keeping with the metal roof panel manufacturer's printed instructions. Install on EPDM pad (not shown) or use a tall clip sized to support the panel on top of the ventilation layer.
- (8) Flush rake-edge flashing
- Note that panel hooks onto outside edge of flashing, which is mechanically secured to the roof deck.
- (9) Architectural metal roof panel
2 RELATED WORK BY OTHERS
- (A) Acceptable deck
- (B) Fascia Board
NOTE: See the Standard for additional requirements.
