I was just talking to a woman I know about the construction of her new home. She is in the phase of lining up all her subs. She was mentioning that her roofer was telling her that the plumber would be responsible for the flashing around the plumbing vents.
To me, that sounds out to lunch. How can a roofer warranty a roof when they diddn’t install the flashing around the vents.
In all fairness, I could be wrong. To be honest, I have never really payed attention to who flashes the plumbing vents. But I have always naturally assumed the roofer.
Am I wrong? Is it different on a case by case basis depending on the specific arrangement? Or is this roofer raising red flags.

It takes a trip back, but I usually insist on flashing the waste vents. I'm probably gonna get a call back anyway whether it's my fault or not.

That was my way of thinking. The roof is your baby right? You want to see that it gets done correctly.
Seeyou does copper roofing. In his case, it's more likely that a plumber would do something incorrect, like putting galvanized in contact with the copper. With ordinary shingles, there's a better chance that a plumber might get things right.

On new work, I like to give the roofers a flashing with a piece of 3" pipe already in it. I make the hole through the sheathing. The plumber never has to get up on the roof.

I like to do that too, but then the plumber pulls in the driveway, sees the vents in the roof, thinks the job is already roughed in, and leaves.
What do you guys use for flashing now? Full lead-topped jack, rubber gasket flashing, or something else?

>>>>>>>>With ordinary shingles, there's a better chance that a plumber might get things right.We do all types of roofing and if it leaks, we get the call, not the plumber and believe me, we get lots of WV leak calls. Those rubber gasket boots that plumbers like last about 5-10 years. We flash 'em with lead or copper or not at all.

Well since we "plumbers" have to deal with electrolosis all the time why do you think that we would put iron next to copper?
Now I might get an over zealous plumber who would want to solder a pipe to seeyous' roof. <g>
To the OP
Remodels---- yeah we put them in & yes I prefer lead unless it's a an "R" panel roof then I prefer metal backed rubber.
New construction we usually supply the flashing & the roofer puts them on.Do you look to the government for an entitlement, or to GOD for empowerment. BDW
"With ordinary shingles, there's a better chance that a plumber might get things right."I needed a good laugh! Thanks!;)On new work, I insisted that the plumber have his stacks in place as needed for rough in, before I would shingle.
On remodels, we work together. I'm on the roof while he is inside driling and pushing out.I have NEVER seen a plumber flash one to my satisfaction, though there are a couple who came close - at least made the attempt!When I started roofing - (in Florida - local customs do vary) common practice was for the roofer to run by and do the dry-in with felt as soon as the plywod was on. Then after the plumber did his rough-in, and the carps finsihed the facia, the roofer was called back to shingle. Sometimes three days, sometimes three weeks.In my first year going self-employed a regular customer called me to do one thirty miles away - on a lake.
his framers had already dryed it in and the shingles were stocked on the roof so I was feeling good about it.
There were no plumbing penetrations but being young, I never gave it a second thought. Laid those sixteen squares and went home. He paid the bill the next day.About three or four weeks later, I got a call from him - "your roof is leaking on that place out at the lake"Curious, I loaded up and drove all the way out. I couldn't imagine what....The plumber had drilled his pipes out from inside, thrown the boots up on the roof from a distnce, and left it like that. I laughed and billed the builder for the trip. That's is where I learned to think like CU and demand that I be the one to install the boots.

around here it's split 50/50
on our remodels the plumber almost always installs the boots.
If the plumber's a nice guy he will supply the boots and possibly even climb up on the roof to slide them over the pipes. Either way, the roofer takes over from there. The ONLY exception I might go for is if the plumber has a very strong inclination to weave them into the felt and shingles... but hell will probably freeze over first.
I ran into my roofer the other day at the lumberyard. We were standing there jawing and I noticed he had a case of 2" pipe flashings in the back of his truck... quantity 100. That tells ya something right there.
In order to flash the vent you need to get on the roof.
The only slanted surface I've seen a plumber walk on is the sidewalk leading to the tavern.
Its the roofers job.
both my plumbers are sober, but they have the body shape that would let them roll off the roof easier than most. I'd be afraid they might stress the structure, LOL

Plumbers don't always get vents up before the roofers are long gone, so it's probably most common that the plumbers assume that they'll have to provide and instal flashing on occation and include it in their bid unless other arrangements have been made.
Having said that, whenever we know the roofers are going to be doing their thing before the plumbers, a quick call will have the plumbers over lickity split to at least get short, temp. pipes through the roof and the flashing for the roofers to install so the plumbers don't have to get up on the roof.
Given the choice of either installing their vents after the roof is on or simply providing the flashing, they'll provide the flashing every time.

That's usually the way it works. All the subs normally have the same goal in mind - give the customer a great job with no call backs and we normally work together to obtain that.

So the concensus is pretty much the roofer should be responsible for the flashing because they are the most qualified to handle that aspect. We're not dogging plumbers here, because there are plenty of good plumbers willing to work with roofers / GCs on the vent flashing to meet the goal of a good finished product. And any roofer that says he won't install the flashing at the roof vents is questionable to say the least.
Is this plumber that is going to the roof flashing the same one that does the "carpentry" when doing the roughin? A sawzall in one hand making space through anything in the way.
