About this asset

Flanged roof vent cowl modeled as a parametric Revit family for plumbing distribution systems, featuring a domed weather cap and slotted intake. Rendered with a utilitarian profile, this rooftop drainage component consists of a flared conical flashing collar that transitions into an integral circular flange base. A protective domed cowl in charcoal grey surmounts the vertical riser, shielding the stack from rain ingress while preserving airflow through vertical perimeter vents. Beneath the conical body, a cylindrical spigot extends downward to engage with vertical soil or waste vent pipework. Clean circular contours and metallic grey surfaces define the assembly, providing precise geometric clarity for MEP penetrations and exterior roof surface intersections.

The download is a 328 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.

In Revit, this family integrates directly onto flat or low-pitch roof planes to terminate drainage vent stacks. The downward connector aligns with sanitary piping layouts, enabling logical system assignments and continuous flow calculations. Designers can coordinate the flashing diameter against architectural roof buildups, verify clearance heights, and manage visibility settings across coarse schematic diagrams or fine presentation views without model regeneration delays.

Essential for multi-storey residential complexes, commercial office buildings, and healthcare facilities, this fixture caps sanitary soil pipe penetrations across exposed parapets and plant roofs. MEP engineers and BIM coordinators incorporate it into roof drainage drawings, technical penetration schedules, and clash detection workflows. The model accurately represents soil stack vents, plumbing roof terminals, and rainwater flashings in architectural documentation sets.
