Have gotten a lot of rain lately and noticed a slight drip coming from the roof thats roughly right below the a/c unit... hoping to get down there Saturday to try and mitigate. Any advice on sealants/how best to attack this problem?

Probably just need to go inside, remove the AC ceiling cover, look up into the AC and find the 4 long bolts in the corners, and tighten them up a bit. It is quite common for the gasket that seals the AC opening to compress over time and start to leak. The cure, other than replacing the gasket which means removing the AC from the roof opening, is to tighten the bolts a bit.

I use Hengโ€™s roof coating and Eternabond tape depending on the situation
