Now THAT'S a flat roof vent

Insulators installed three of these to ventilate the 14" attic space above a top floor condo unit.
Unfortunately, they neglected to fully bull and strip the cut in the modified they made to install the base. About a six foot diameter chunk of ceiling came down in the last big rain just underneath the vent.

yeah you have to roof those things in,
needs to be flashed with the roof material,
up the sides, and terminated.

good luck.


Got a pic of that thing full on from the face or a corner (looking IN)?

Were the “installers” roofers or metal guys?

They were the insulating crew. Didn’t think they needed a roofer.
