(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 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.
(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
