I guess it is a roof leak - now what

Several months ago I noticed that my wife's BedBuddy was damp when I pulled it out of the top shelf of the "closet" on her side of the bed. I checked around to see if there was water elsewhere in the closet but everything was dry and there were no stains indicating a leak. I figured that maybe the BedBudy was put away hot and the dampness was just condensation. Over the next few months I kept checking and it never was damp again.

Today I was out in the trailer and looking for something and I opened up the closet door and went to move some sweatshirts on that top shelf. They were both pretty wet so I pulled them out and started investigating. Just a note - we've had over 4" of rain in the last week and the TT sits in the driveway in a slight nose down orientation) There was no pooled water but there were a couple drops of water on the curved part of the ceiling near the back of the closet (forward relative to TT). Next I got out the ladder and climbed up to have a look at the roof. Pictures below show the seams as they are today - ugly but they look like they are intact.

I plan on buying a roll of EternaBond and sealing the joint between the TT front skin and the roof. I will also likely seal the side to roof joint at the same time just to be preemptive against future leaks.

So here's a couple questions - do I need to peel back the interior wall to check/dry out what may be there as well? We live in the San Diego area and soon the temps will rise and the humidity will drop - would that dry things out satisfactorily without removing the wall & ceiling panels in that area? Last but not least, the current sealing goop looks OK - not cracked or gapped - do you think this is where the water got in or is there more to investigate?

TT is almost a year out of warranty so this is all on us to fix.

on the first photo I would take a razor blade and shave off the tops of those clumps of sealant to make it as level as possible, then use maybe two strips of 3" Eternabond, enough to have about 1 inch plastered flat on each side with an overlap of maybe 1/2 inch where the two strips join. It is hard to judge the width you need, maybe just a 4 inch wide Eternabond... you have to be the judge...

Be sure to clean the area well... I used paint thinner, (which really cut the gunk on the roof) then quickly followed by 90% isopropol alcohol (IPA) to remove all traces of the thinner... when dry then apply the Eternabond in 3 foot sections, overlapping the edges, and rolling it down with a wallpaper edge roller.

I describe in detail here...

I would certainly aim a fan into the inside area to dry as quickly and throughly as possible.

roofs seldom leak. It is the junctions and attachments that leak.

That pile of caulk on the roof concerns me. I doubt it came from the factory that way.

The pile of more stuff on stuff is not a good plan.

Roofs are either rubber or plastic. Nothing really bonds to rubber very well. Not forever. Plastic uses glue that does often sort of melt the plastics together.

Check your front clearance and marker lights as well.

I had a similar situation with a previous TT, actually woke up one day with water dripping on my forehead!

After I found the leak, like you have, and re-caulked, I also had the same concerns...mainly mold or mildew going forward.

My investigations, with the manufacturer made me feel fairly confident that the wall boards, insulation, etc. would not soak up or maintain a lot of moisture.

To be sure, I ran a dehumidifier for a couple months and let it drain directly into the grey water sink drain.

I never did have any problem with peeling, or bubbles in the interior paneling.

I'm sure you're just looking to find a comfort level, so that's my story.

Good luck

Thanks all, I appreciate the suggestions.

rsdata - I put the fan in there earlier this morning and will let it blow for a few days. So do you think peeling back the interior skin is unnecessary in my case? 4" tape will give me the 1" overlap - and thanks for the suggestion on shaving the lumps off.

Tom - we bought it new from a dealer in Riverside CA and that's exactly how it looked when we got it. There were/are plenty of build quality issues with this trailer so no surprise the sealing looks bad.

Bob - I hadn't thought about that but I'll pull the clearance light nearest the wet cabinet and see what it looks like

When I did mine, I was able to get a fair amount of the caulking off by peeling it carefully using a plastic scrapper. I had globs of sealant that would extend up to 2" from the seam. Then I used a knife to trim it down.

That is a pretty sloppy sealant job, I'd almost be certain that is where your water is coming in. Trim down as others have suggested and put some tape on yourself being mindful of where you are directing water with it. If you're handy, nobody will do the job as carefully as you will when its your own stuff. I second the suggestion of checking marker lights, we have a friend who developed a leak at the light and it went unnoticed until the interior panels started warping.

I wouldn't worry too much about the moisture in the walls if you caught early and there are no signs of damage to the wall boards. Once you stop the water intrusion, it dry out especially if you have a fan or dehumidifier in there to recirculate air around.

+2 Eternabond tape

Sticky stuff, once you peel it off the roll you get one chance to put it into position. If it sticks to itself, i.e. both sticky sides then throw that section away.

Looks like they were piling caulk on top of the hold down screws. Uniform spacing.
