If the reason the caulk and stuff was pasted on the roof was to cover a crack, then you need to be sure the crack has not gotten longer. If you find any cracks in sheet metal, take a small drill bit, maybe 3/16" in size, and drill a hole at the end of the crack. This will keep it from getting longer over time as the road vibrations work on it. Drilling the hole gives a stress relief point aso the crack can't extend from that point. Then recoat, caulk, or Eternabond the roof over the crack to seal it up.
