Roof Leak

Trailer still appears to be in good condition, but there are signs of a water leak in front right corner of trailer.
No sign of water damage on wall, but front storage has depressed wood floor near hatch door and small pile of yellow "powder" sitting just inside hatch door on ledge. Inside two tissue boxes seem to have absorbed water with discolored tissues all stuck together.

OK, so I'm assuming a roof leak that hopefully just needs some caulking. Any advice on confirming that I have caulked the right place and that leak is just from aged caulking leak?

What kind of caulk should I use?
  • Do a pressurized cabin air leak test would be my suggestion. That may not be the only area where you have failed sealant and/or leaks.

    Dicor self leveling lap sealant is a Forum favorite for sealing on EPDM roofs. Eternabond tape is extremely good, also.
  • If you have a walk-on roof, use the water hose, and also from the ground level in that area.
  • Dicor Self Leveling caulk on the roof.

    Consider covering the seams with Eternabond.
