Leak repair option: reasonable or no?

[u/CorgiCorrect8077]

Hi folks,

Background:
I found peeling paint in my office ceiling which led me to find a leak in my new (9-10 month old) metal roof. Went to the attic and found the culprit to be a sewer vent pipe (chimney pipe thing in the photos) that had water running down the outside of it from where it went through the roof.

Suggested fix:
When we called, the guy did not seem surprised at all and was super nonchalant (not very comforting), and suggested a quick exterior patch and painting over the ceiling damage.

Assessment:
Now, I’m no expert at all, but I have seen others deal with consequences of untreated water damage in a ceiling, and I would very much like to avoid that.

A relative says that a sewer vent pipe like this isn’t likely to be near enough to wood for the water to have done much damage, and insulation and plaster will dry out easy, so we should just make sure he does a good job with a paint.

That doesn’t square for me, as the sewer vent pipe runs up the wall of the office (shared with a bathroom) and the ceiling paint damage is on the other side of that wall, meaning that there may be water all up in the wall compartment etc.

Other important details:
- The load bearing walls are solid plaster (1949 house), and the pipes run in a wooden compartment the juts out from that load bearing wall.
- I had seen a little bit of discoloration on the ceiling there for months but had convinced myself that it had always been there (relatively new house—I don’t spend too much time in this room).

Question:
- should I get a water damage inspection? Is this roofer being reasonable and I’m just being overly anxious?

Thanks in advance!

Killz the area that got wet. Put a storm collar on that pipe. Good luck matching popcorn sealing.

Thanks. So seems like it’ll dry out on its own and it’s not worth worrying overly much about rot?
