SBS Details
1 WORK INCLUDED
- (1) Primary Roof Membrane
- Installed per RoofStar Guarantee Standards.
- (2) Membrane Flashing
- Carried up walls a minimum 200 mm (8") above roof surface. At window curbs membrane flashing must be 200mm (8") in height above the top of extruded polystyrene insulation or protection/drainage layer, extended under the window mullion (fenestration assembly) and carried to the inside edge of the curb. Membrane gussets must be installed at all corners and transitions.
- (3) Protection/Drainage Layer - Insulation Surfacing
- Assemblies to be determined by Design Authority. Paver systems are required to have proprietary pedestals that incorporate a minimum 3mm (1/8") gap between adjacent units. See additional RoofStar Guarantee Standards under 12.1 Protected and Modified Protected Membrane Roof Assemblies.
- (4) Metal Wall Flashing
- Required on roof assemblies using gravel ballast, filter mats and drainage mediums at insulation /curb interfaces.
2 WORK BY OTHERS
- (A) Acceptable Supporting Deck Structure
- Concrete slab shown
- (B) Supporting Curb
- Height varies depending on the insulation thickness and type of roof assembly.
- (C) Metal Water Stop Flashing
- Mechanically attached to the top of the window curb. Cut flashing to fit the opening and pan fold, weld, or solder seams at all corners and mitres.
- (D) Metal Water Stop Flashing Seam
- Overlap metal water stop joints a minimum of 150mm (6") and seal joints with two rows of structural sealant.
- (E) Building Envelope Membrane Flashing
- Must be compatible with and overlap the roof membrane flashing. Membrane gussets must be installed at all corners and transitions.
- (F) Metal Cap Flashing
- Adhere metal cap flashing to membrane flashing with a membrane compatible structural sealant. Mechanical attachment of metal flashing through the membrane flashing is not acceptable.
- (G) Fenestration Assembly
- CAUTION - Securement fasteners MUST NOT penetrate the metal or membrane flashing.
- (H) Fenestration Assembly Securement Bar
- Fasten securement bar ONLY through upper vertical leg of the window mullion (frame).
NOTE: Refer to RoofStar Guarantee Standards for additional requirements.
