A friend of mine bought a 60’s “plain ranch” for use as a rental. 3 BR, 1 bath, kitchen/eatin area & LR. 1 car garage.
I was in the attic checking it out and notice that the kitchen range hood and the bathroom fan just terminate in the attic.
The house has 3 layers of shingles on it and the insurance company is requairing that it be replaced.
A roofer was looking at it to give a bid. I told him that it needed termination added for the kitchen and bath vent fans.
He said “no, you just run the pipe through the roof and we install the boots”.
I hope that he misunderstond and was thinking that I was talking about the the plumbing vents.
But it does bring up the question of how is the location for the terminations determined.
I am not too concerned about the bath fan. Flex duct makes that easy to hook up.
But what about the stove hood. It currently ends in with a retangular section.

Depends on the subs for me.
Some HVAC will do the re-work of the shinhgles or roofing, but most strongly prefer not to .
Usually the hole is cut, and a roof jack made for the vent type is supplied to the roofer for installation while roofing is being installed, vent pipe is then brought to that point by the HVAC crew.
What dovetail said.
Roofer will pretty much spot the roof jacks where you tell him - boring a hole through roof sheathing from the inside and poking an old coat hanger wire out of it as a marker is a pretty reliable technique.
The range hood vent which is rectangular can be transitioned to round in attic if you cannot get a jack for rectangle.

In my exp it depends on who's on the ball.
One job in particular comes to mind, it was standing seam copper, and the plumber was willing to go along with our plan, and he routed the vent stack to miss a standing seam, thus saving us some grief.
But most time that stuff is already in when we got there.
I can't see how it would be the roofers job t extend the existing attic vented stuff. Get it out to the sheathing and he takes care of the flashing, thats all.

What Duane and others said. Others get it to the roof. We make it not leak. And we charge double when a plumber/HVAC cuts a hole in a new roof and spreads tar on it. We often have to go back when the plumbing/kitchen is installed to install the roof flashings for the penetrations.

Thanks. I don't want to go mucking up a new roof either.But since this is reroof, with 3 layers coming off it makes it a little different.But if I would drill a 1" hole in the sheathing, which I should be able to do without going through the shingles. Poked a coat hanger through the shingles. So that after they strip the roof that the 1" hole is there marker.Gave them the vent caps, they SHOULD be able to place the.But to accept an 90% probablity that they will have come back and place them. Specially right now. 50% of the houses on that street are getting new roofs due to hail..

We usually have to come back and install the boots. I've got one guy that does stuff like that all day. Just drive a nail (or a screw ) thru the sheathing where you want the boot and they should be able to center it on that.http://grantlogan.net
