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.
(8) Flush rake-edge flashing
(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.

 === WORK INCLUDED ===
-;(1) [[RoofStar Guarantee Standards for SBS Modified Bitumen Membrane Systems#SBSMEMBRANES|'''Base Membrane (field)''']]: See Tables '''9.1''' and '''9.2''' for acceptable membrane types and application methods.
+;(1) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMHOOKSTRIP | '''Separation membrane''']]: Separates the deck and the metal edge flashing.
-;(2) [[RoofStar Guarantee Standards for SBS Modified Bitumen Membrane Systems#SBSPERIMETERS|'''Base Membrane (flashing)''']]: Carried vertically up a wall or parapet (membrane flashing must extend up the vertical plane, and above the ''Finished Roof/Waterproofing Surface'', at least 200 mm (8”), and must extend onto the roof field at least 100 mm (4”) (greater if required by the membrane manufacturer).
+;(2) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMFLASH-SECURE | '''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) [[RoofStar Guarantee Standards for SBS Modified Bitumen Membrane Systems#SBSMEMBRANES|'''Cap Membrane (field)''']]: May be an ungranulated base membrane when protected from UV light.  See Tables '''9.1''' and '''9.2''' for acceptable ‘film’ cap membrane types.
+;(3) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMHOOKSTRIP | '''Continuous eave metal flashing''']]:
-;(4) [[RoofStar Guarantee Standards for SBS Modified Bitumen Membrane Systems#SBSPERIMETERS|'''Cap Membrane (flashing)''']]: Extended vertically past the termination of the base membrane flashing, to provide a positive seal at the top edge.  Membrane flashing must be protected from UV light exposure; use a granulated surface membrane (as illustrated) or cover with metal flashing.  Terminate membrane following the requirements in '''10.1.2.2''' ('''16''').  For perimeters that require hot works-specific applications, see '''10.3.3 Alternate Membrane Flashing Approaches'''.
+;(4) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMUNDERLAYMENT|'''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) [[RoofStar Guarantee Standards for SBS Modified Bitumen Membrane Systems#SBSPROTECTED|'''Drainage Layer''']]: Required below XPS insulation in a PMRA (an additional drainage layer is sometimes required above the insulation.  See '''14.1.2.1''' ('''5''')('''4''').  In all other cases, a second drainage layer above the insulation is discretionary).  Turn the drainage layer up at the perimeter to convey water to the drains.
+;(5) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMUNDERLAYMENT|'''Underlayment''']]: Applicable for all Architectural Sheet Metal systems.  For slopes less than 1:3, the entire roof slope must be covered with a <u>self-adhered</u> underlayment.
-;(6) [[RoofStar Guarantee Standards for SBS Modified Bitumen Membrane Systems#SBSINSULATIONMATERIALS|'''Insulation''']]: XPS insulation, ideally installed in multiple layers that are offset and staggered as illustrated (for both system stability and thermal effectiveness).
+;(6) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMSEP-VENT|'''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) [[RoofStar Guarantee Standards for SBS Modified Bitumen Membrane Systems#SBSPROTECTED|'''Filter Fabric''']]: Installed above XPS insulation, and tucked behind the base metal flashing, to contain insulation and prevent ‘stacking’ (see '''12.1.1''' ('''1''')('''3''')('''1''')), and to prevent fine material from settling down to the membrane ('''12.1.1''' ('''1''')('''3''')('''2''')).
+;(7) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMCLIP|'''Metal Panel Clip''']]: Installed in keeping with the metal roof panel manufacturer's printed instructions.
-;(8) [[RoofStar Guarantee Standards for SBS Modified Bitumen Membrane Systems#SBSPROTECTED|'''Ballast''']]: Considered part of the roof system (ballast functions as securement against both flotation and wind uplift), ballast must be installed by the Contractor (see '''Section 12.1''').  This requirement is waived when a ''Vegetated Roof System'' (VRS) that is installed by others serves as ballast (see '''12.1.3.1''' ('''1''')); in such situations, the VRS must be installed immediately after the Contractor’s work and coordinated with the Contractor to ensure the roof system remains unaffected by wind or flotation and is not damaged by others.  See also '''1.6 RoofStar Guarantee: Coverage and Limitations''' concerning integrity scans when overburden is installed by someone other than the Contractor ('''1.6''' ('''6''')).
+;(8) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMHOOKSTRIP | '''Flush rake-edge flashing''']]:
-;(9) [[RoofStar Guarantee Standards for SBS Modified Bitumen Membrane Systems#SBSMETALBASE|'''Metal Base Flashing''']]: Fabricated and secured according to the requirements in Part '''13 METAL FLASHINGS'''.
+;(9) [[RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems#ASMPANEL |'''Architectural Metal Roof Panel''']]
