If you remove the Dicor sealant you should find the mystery leaks. Over time the Dicor can crack and also lose adhesion. In only 5 years I found places where the Dicor was just laying on the roof. Also found a hidden bubble where they poured on the Dicor and there was a bubble in it that did noting to seal. I removed the Dicor to get better adhesion for the Etearnabond tape Found a rusty screw head (water must have gotten in) and a broken off screw. Also found staples that were coming up. All fixed and taped over.
My main thing is, once you have tape, why paint the roof??
