Notice to Reader
Images used in a Construction Detail are representative and not intended in their representation of an assembly to be prescriptive. Nor are they necessarily drawn to scale. Rather, they are provided to visually convey the Standards, Guiding Principles and Recommendations of the RoofStar Guarantee Standards for a Waterproofing or Water-shedding System. Actual design with respect to dimensions, the selection of materials and their application remains the responsibility of the Design Authority. The full text of applicable RoofStar Guarantee Standards may be read by using the blue hyperlinks

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 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

2 RELATED WORK BY OTHERS

(A) Acceptable deck
(B) Fascia Board

NOTE: Refer to RoofStar Guarantee Standards for additional requirements.
