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) 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
