I see nothing wrong with both proceeding at the same time. Most
plumbing I have seen was waterproof and if both are proceeding at
the same time, the job obviously is moving long faster. It should
be the roofers job to install the flashings while it is being
roofed anyway..

I'm surprised by teh responses to this post. Especially Matt's post since
he is usually right on.
Perhaps this is regional...like gutters before siding in Seattle.
In the South, however, the norm is that as soon as the framing rough is
complete, the plumbers begin their rough-in.
Once the plumbers are substantially complete, the HVAC guy gets in there.
On thier first day, they make all their roof penetrations for gas flues,
bath exhaust vents, etc.
Then, the roofer installs shingles on the house. The roofer will use the
"pipe flashing" that the plumber left for him to flash around the plumbing
stacks. And the roofer will be able to properly shingle around all the
other vents.
And here's why:
Plumbers are not roofers and should not be on the roof. If the shingles are
on before the stacks are through the roof, the roofer has to return to
repair a roof that could have been properly installed.
HVAC guys are not roofers and should not be on the roof. If the shingles
are on before they get there, they'll have to get on the roof to flash
around their penetrations.
Further explanation on the two preceding paragraphs:
If you shingle first, someone HAS to get on the roof. But there will no
longer be toe boards so it is much more dangerous. Since they will be up
there for only a few minutes, it is unlikely that they will use harness and
be properly tied off.
Plumbers and HVAC contractors probably do not even own the proper equipment
to safely navigate a steep pitch. Do you want them on slippery shingles
with no toe boards and no harenssess?
Instead of freaking out about the roof now, you should have made sure your
framer did a good job "drying in" the job with felt. And you should have
used Advantech so it won't matter if it gets wet a few more times.

Maybe. Around here with our fairly wet weather, we dry in the house as
soon as possible and nothing is going to delay that, not plumbing vents
or anything else. The plumbers here are quite capable of installing
vents through a shingled roof. Mine did so with no problem at all. I
have four penetrations (I have two attic furnaces) and all were done
very professionally and none of leaked after 6 years. The plumbers had
no problem working on my 16/12 pitch roof.

he's just trying to get out of having to get on the roof. Get your roof on
first.
