Resealing Roof Joints and Penetrations
I've seen others post that they reseal joints and penetrations in the roof every year or so with Dicor. I've never done this, but I can see some areas on my roof that would be likely locations for so...

FI, I see most users just apply Dicor over the old stuff. It doesn't make sense to me as the sealant that is covered is still deteriorating and cracking. If you go the sealant route, I would remove as much of the old stuff as possible.
I used Eternabond on my roof and was sceptical on the properties of the tape (mainly from the almost 100% positive reviews). After applying the tape and doing a blower test on the TT, I recommend Eternabond, heartily. Areas that were sealed with just sealant still had tiny pinhole leaks but everything with Eternabond was leak-free.
