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) Deck overlay
Required for continuous support of the underlayment when the deck is not suitable.
(2) Underlayment
The type of underlay required is determined by roof slope.
(3) Insulation
Offset and stagger layers 300 mm (12").
(4) Separation layer
Vapour-permeable layer over insulation, required on all insulated Architectural Sheet Metal Roof Systems. The material must be located between the insulation and metal panels (see 8.1.2 Design).
(5) Ventilation layer
Recommended over asphaltic underlays and / or as required in this Standard (see 8.1.2 Design).
(6) Bearing plate
Only thermally non-conductive clips or bars passing through the insulation assembly, or mechanically fastened bearing plates, may be used to secure and support insulation panels, or provide support for panel clips.
(7) Architectural metal panel clip
(8) Architectural metal roof panel (lower)
Lower, installed prior to the pipe flashing, cut hole large enough to allow for movement. Extend 400 mm (16") upslope beyond the pipe.
(9) Overlap area of lower panel
Penetration flashing is mounted here, set in an acceptable sealant.
(10) Spaced Cleat
Cleats, set in accepted caulking, spaced 50 mm (2") and fastened with compatible non-corrosive flat head screws.
(11) Sealant
(12) Architectural metal roof panel (upper)
Installed after penetration flashing. Cut hole for pipe penetration and turn lower panel end under to hook onto cleat.
(13) Protrusion Flashing
Flange set in two continuous beads of accepted caulking.
(14) Sealant
Applied around base of penetration flashing.
(15) Settlement Cap
Material must match flashing material.
