Renovating the bathroom and found these dark patches in the joists and roof lumber surrounding the old vent pipe. The PVC part is new.
Anything bad here? Anything we need to address?

That's signs of a water leak. The flashing around your vent is either non-existent, or is failing.
We had the roof replaced two years ago. I believe they redid all the flashing at that point. So there's a chance this could be old? If the leak is resolved, which I'll verify, do we have to do anything to the wood or are we good?
They probably fucked up the flashing. Roofers and siders fuck up all the time. If it’s truly an old leak that’s been fixed, you have nothing to worry about. Go up there and observe during the next strong rain. Edit: grab a house key or a screwdriver, stick into the wood. Does it penetrate really easy? Then you’re fucked. Else you’re fine, as long as the leak isn’t active.
I mean I could just spray a hose up there, couldn't I?
Yes, but it’d help if someone else observed and recorded to really nail down what’s happening.
I had water penetrating the house after the siders fucked up. Took opening the ceiling and recording the penetration to really understand what the idiots did wrong.
