Dicor question.. I'm not sure, need help
Roof material is TPO confirmed by manufacture. Roof edge folds over and is held on by something like this. I want to seal on top of the metal. Just a little ribbon of caulking...

You should also take off that trim strip and caulk over the screw heads that hold the gutter on. The screw heads are a common point for water intrusion.
Excellent point every external screw is a prime candidate to wick and cause horrendous damage unseen for months or years. I'm a firm believer that caulk of anykind except for the 3M 4000/5000 Marine adhesives/sealants should only be used as a second line of water defense. Exterior lights and their mounting screws and wire penetrations are another great source for water damage. I have developed what I think are fool proof guaranteed methods to take care of these potential issues using a combination of Eternabond double sided and Roof Seal tapes. See the link in my signature for details.
