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?

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?
Might spray it with some antifungal just to reduce chance of mold forming
