That’s correct. The term roof jack has been used for decades referring to something completely diffrent. It a vent stack cover. Any other term is “jacked”.

Roof vent, really? So you argue that a roof jack describes something totally different and advise me to use the term roof vent? Please help me understand how this flashing assembly is venting the roof. I am no aerospace engineer but pretty sure the item in question is a flashing assembly to weatherproof a penetration in the roof. No?
And yet again, another name to describe the flashing assembly “vent stack cover”. Sure it is. The description “roof jack with vent cap” was used to describe the type of vent stack cover/flashing used. The same term used by the manufacturer of the product. I get the argument about the term roof jack also describing something completely different. But in the context of discussing a vent pipe flashing assembly, the description used is differentiating this vent stack cover from the other styles.
But you got all the answers and argue with people “in the know”. Call it whatever you want and move on. Call it a roof jack and you’ll have some siding installers laughing their but off LOL.

Justin, I stand corrected. In the Dictionary of Construction Terminology, the term roof jack is defined as
“Sleeves that fit around the black plumbing waste vent pipes at, and are nailed to, the roof sheeting”
In my own reports, however, I would still not use it. If the client looked of the term on the internet he would find:
Roof jacks * provide a stable surface to work, increasing safety and making it easier to apply roofing . Ideally, locate a rafter below the sheathing. (You can usually feel sheathing nails, which are driven into rafters through the underlayment.) Attach a jack by driving two 16d nails (never roofing nails) into a rafter." JMO
Good Luck!
