A gooseneck pipe penetrates a concrete roof assembly, protected by a roofing membrane and flashing system detailed per architectural drawings. A collar seals the pipe above the roof flashing, which sits eighteen inches below the screen opening fitted with a one-hundred mesh size screen. Below the roof slab, pipe supports are anchored with drop-in concrete anchors and secured by threaded rods and clamping hardware. Fire-stopping is provided around the pipe penetration through the concrete roof slab.
