Leak around previous furnace exhaust vent in basement
This spring Lots of melt lately but nothing additional in terms of drip, but continued small leak along outside of vent pipe. Rained heavy early this week, but nothing more then the same leak.
Snowed a lot later in the week, and today's melt I'm noticing the leak is on the other side now also. But it's not dripping at the end of the vent on the other side, from where I can see. I have a cut in the plywood just a couple inches away and see a drip coming through there. The wood along 2.5 sides of the vent are wet.
In the pic where it's red marked, is wet. The 2 red circles are the spots where water is dripping. The blue is where it's dry and not wet.
Think there is some roof work that needs to be done around the old vent? Maybe some cracking of the sealant or bad shingles?
We went up to the roof to take a peak in the fall, but didn't see evidence of anything wrong (mind you I'm a first time homeowner).
Any suggestions on how to proceed and what it likely is?
