    Default plumbing vent on roof

    I hired a licensed plumber to put a 2nd bathroom upstairs in my 2 story house. I'm a single parent and don't know much about plumbing but the vent stack is at a 45 degree angle when you look at it outside. He said it can be like that but no less than 45 degrees. Other houses look like the stack is straight up. Will it be okay that way

    i can't imagine it will create a problem, i believe the issue is how high above the roof it extends. i've never seen one like that but i'm sure one of the plumbers here will let you know if it's right or wrong.

    the only thing i can think of is that he had to run the vent up on a 45 within the attic for a portion of it because something was in the way.. but then couldnt get at it to switch it back to running plumb.. that or he was being lazy
    fire up the saw and make some dust

    There can be no reason that the vent should be at a 45 degree angle. It's just poor workmanship. He needs to take some pride in his work. My feeling is that is the one thing everyone can see that drives past the house. I wouldn't want my name on it.

    Unhappy Re: plumbing vent on roof

    I'm getting scared. I already paid him and the drywallers are starting tomorrow. Other than it not looking right, will it work right.

    It will work. The only question I would have is what type of flashing did he use on the roof? Most vent flashing's are designed for vertical vents. If it doesn't leak I guess it's OK. I would be more concerned about the work he did that can't be seen.

    The roof is metal and he used a metal rimmed boot that was made to use on metal roofs. I hired a carpenter to put that on the roof because the plumber didn't want to go up there. He said that was a carpenters job.
