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) Underlayment: The type of underlay required is determined by roof slope.
(2) 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.
(3) Architectural metal panel clip
(4) 'Z' Closure: Set in accepted sealant or butyl tape and secured with compatible non-corrosive flathead fasteners.
(5) Sealant
(6) Drag-load fasteners: Compatible non-corrosive fasteners.
(7) Architectural metal roof panel: Top end of panels must be "bread-panned".
(8) Ridge cap flashing: Cut away to reveal 'Z' closure and drag-load fasteners.

NOTE: Refer to RoofStar Guarantee Standards for additional requirements.
