Sunroom roof in Florida needs replacing

I bought a home in central Florida with a sunroom that looks to have a metal roof with a tar and something else coating. The coating is coming off and the tape of the seams is peeling off as well. Please see pictures for more details. The roof is probably 12 years old or so and doesn't leak, but I want to get the roof in top condition so it will last another 10-20 years hopefully. I'm pretty handy and would like to do it myself. Not sure if I should get another metal flashing type product and cover the entire roof or what. I think removing the white silicone and tar type stuff that is the top coating of this roof would take a lot of time. The roof doesn't leak currently. I've looked at the silicone paint type stuff from Home Depot, but videos from roofing people say that it doesn't last and I'm not sure how it would bond with my current roof situation. Any advice as to what I should do?

It looks like someone applied a coat of roller grade roofing tar to either combat rust or minor leaks [maybe both] then found out how hot the black roof made the room and applied an elastomeric roof coating over the tar. Most of those types of roof coatings last an average of 5 yrs.

IMO removing the existing coating would be way too much work! I'd scrape off whatever is loose and recoat with either the elastomeric roof coating [latex] or fibered aluminum roof paint [oil base] I'm not sure what the silicone paint you referred to is.
