About this asset

A circular roof vent cowl and flashing collar, this MEP Revit family provides detailed terminal geometry for 110 mm plumbing and soil stack vents. The assembly comprises a low-profile mushroom cap, an integral perimeter slotted air grille, a flared central collar, and an expansive circular flashing flange. Rendered in contrasting dark charcoal for the hood and base trim alongside a light body sleeve, the terminal features concentric sealing rings across the perimeter flashing skirt to seat flush over roof waterproofing membranes. Below the mounting deck, a straight cylindrical spigot provides connection down to nominal 110 mm soil and waste pipe stacks. Smooth filleted transitions minimise rainwater ingress while allowing unimpeded upward exhaust ventilation.

The download is a 338 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Designed for architectural and MEP coordination in Revit, this component places onto flat roof surfaces or integrates directly above vertical plumbing runs. Users can align the terminal with building drainage layouts, verify roof penetrations against structural framing, and assign standard pipe materials. Clean nested geometry ensures lightweight performance in project models, sections, and roof coordination sheets without cluttering system views.

This terminal fits residential apartment buildings, commercial facilities, institutional projects, and industrial warehouses requiring dedicated sanitary soil vent penetrations or roof passive air relief. Frequently paired with built-up membrane roofs, parapet assemblies, single-ply systems, and soil stack riser drawings, it provides clear clash detection during detailed design stages. Typical search terms include roof vent cowl, soil stack terminal, plumbing vent hood, flat roof breather, and 110mm pipe flashing.
