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.

1 WORK INCLUDED

(1) Underlayment

The type of underlay required is determined by roof slope.

(2) Insulation

Offset and stagger layers 300 mm (12").

(3) Vapour-permeable separation membrane

Installed over insulation and required on all insulated Architectural Sheet Metal Roof Systems. The material must be located between the insulation and metal panels/ventilation material (see 8.1.2 Design).

(4) 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.

(5) Architectural Metal Roof Panel

Clips not illustrated.

(6) to (10) Pipe Boot

Set in two continuous beads of acceptable sealant.
Secured with high-domed gasketed cladding-type screws.
Clamped to penetration with a stainless steel drawband.
Sealed between flashing and penetration.

(11) Water-tight storm collar: Installed by other trade (new construction only) or as required in this Standard. See 11.3.3 (5).

2 RELATED WORK BY OTHERS

(A) Pipe penetration

NOTE: Refer to RoofStar Guarantee Standards for additional requirements.
