(3) Starter Course: Consists of same type shingles used for roof, applied tabs facing up the slope.
(4) Strip or Standard Shingles: Applied as recommended by manufacturer. Laminated shingles are not acceptable for this application unless expressly permitted by the manufacturer.
(5) Compatible Mastic: Heavy bead of compatible asphaltic mastic at rakes (gables) and valleys.
(6) Protrusions: Curbs and skylights must be flashed with underlayment so as to shed water, with minimum 125mm (5") up vertical surfaces and 150 mm (6") lapping onto field surfaces. Vent stack underlayment flashing should fit tight to the vent pipe and be sealed with compatible mastic. For fire-rated stacks or hot pipe protrusions, strip in secondary metal deck flashing before installing rated stack / pipe flashing.
