Trying to find source of leak from roof

"Vaseline"? Y'think that's a permanent fix?

I have a 2002 National Sea Breeze and I had small leaks along both the front and back seams. I kept adding a little Dicor sealant and it would help, but I didn't get it completely stopped until I cleaned off all of the old caulking and re-caulked all the way across. If I have another leak, I'm going to use the tape that everyone says works wonders, but for now, I don't have any leaks at all.

One other leak that I had was with the skylight in the bathroom. I caulked all around it two times and I would still find a little water on the floor after every rain. The problem was that there was a hairline crack in the middle of the clear plastic dome. I put a little caulking on the crack and that fixed it.

Good luck finding your leak.

Agree with Bud from Moses Lake, tighten the a/c unit down.

Tighten the air conditioner.

Reseal all of the joints and penetrations. Our 08 developed a leak that showed up at the lower front corner of the bedroom slide and once at the rear A/C unit. The leak was a visually undetectable crack or separation of the Dicor at the shower skylight. You are wasting your time trying to pin point the leak.

The strange thing about water leaks is that they can come from some place that is nowhere near where they're coming inside. If water comes through around one if the outside lights in front of the unit, it can pass all the way to the opposite end of the unit and come inside in the rear. Best do like popeye said and bring it to a dealer that can do the pressure test.

A bit more information would be helpful if you're looking for an answer. Where is the water showing up? Around a skylight, vent, ? I just had some leaks around both and had them all resealed. Just when I thought it was done, found another which was coming from the gasket under the roof AC.

What kind of roof do you have on your coach. Is it rubber, fiberglass or what? If it is fiberglass it could be where the one piece roof top meets the sidewall. You might have cracks on the caulking. The same where the front and rear caps meet the top cover. Best thing to do and that way you do not have to worry about leaks ever again is to buy a couple of rolls of Eternabond tape four inches wide and just lay it over the seams on a warm day. But water could also be coming in from a bad seal on your clearance lights, an antenna seal, skylight caulking, TV antenna's.

Now if you have rubber? Not sure!

The bigger or better equipped dealers can put a blower in it and pressurize it and spray soapy water to find the leak(s)
