1 WORK INCLUDED

(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) Base field membrane
Carried continuously over the outside edge at least 50.8 mm (2”) downward, or 50.8 mm past any cold joint.
(4) Sealant or mastic
Applied on membrane, beneath metal edge flashing.
(5) Metal edge flashing (flush with roof surface):
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).
