To get on the roof, place a piece of plywood or other sheet goods on the roof to spread your weight out. Remove the silicone you put on the trailer. 3M makes an excellent caulk remover, apply it on the caulk, place saran wrap on it, and wait overnight. The caulk will come off with light brushing or scraping. Follow up that with mineral spirits to remove the last bits of silicone. Apply Dicor or Eternabond tape.
I will absolutely guarantee that the silicone sealer you used will leak and the bond will break. No silicone, please.
