- (1) Suitable field substrate
- May be the roof deck or deck overlay (if an uninsulated system), or insulation and an overlay (if conventionally insulated).
- (2) Primer or adhesive
- For self-adhered or adhered membranes, as required by the manufacturer.
- (3) Field Base Sheet Membrane
- Selected to conform to the requirements in Membrane Composition, Thickness, and Selection Table 9.2.1.1. and conforming to the options or requirements in a Tested Assembly, an Assembly with Proven Past Performance, or a custom-engineered assembly. Carried continuously over the outside edge and down the vertical face at least 50.8 mm (2”), or 50.8 mm past any cold joint.
- (4) Sealant or mastic
- Applied to field base sheet membrane, beneath metal edge flashing.
- (5) Metal edge (flush) flashing
- Fasteners spaced no more than 203.2 mm (8”) on the top face in two offsetting rows.
- A hemmed drip edge (shown) is required (Refer to Article 13.2.2.1. for fabrication requirements).
- (6) Membrane flashing strip
- Applied to the metal edge flashing and overlapping onto the field membrane at least 101.6 mm (4”). Prime when required by the manufacturer (primer illustrated).
- (7) Field Cap Sheet Membrane
- Selected to conform to the requirements in Membrane Composition, Thickness, and Selection Table 9.2.1.1. and conforming to the options or requirements in a Tested Assembly, an Assembly with Proven Past Performance, or a custom-engineered assembly. Installed according to Part 9 requirements.
- (8) Edge mastic
- Apply mastic or another membrane-compatible sealant to the outer exposed edge of the field cap sheet membrane. Coat with granules.
