Remove or caulk over roof seams?

Hi Bob. Yes, the "plan" is to trade the unit in. Then again, I need to ensure that the thing is well protected in case that plan gets delayed. The current seams are from the factory, and while the edges are starting to lift up, there is still good adhesion for the most part. I think a thorough cleaning and touch up will do the trick yearly until I get rid of her.

Thanks for the comment. Hope all is well on your end!!
