Roof Center Trim Caulking

[Bill]

Brad -

That is truly ugly.

The TM has weep holes on both sides, at the rear end of those trim pieces. However, the holes are neatly drilled in the trim itself, and they are certainly not just random missing spots in the caulk. To the best of my knowledge, there are no weep holes at the front end of these trim pieces. The picture below shows the weep hole just behind the awning.

Thanks for the picture of the center trim cross section. Good to know, since I have to recaulk mine soon.

On my trailer, the gap between the roof and the awning is well-caulked along its entire length. I think the idea is to keep rainwater from washing crud into the gap, which would drool down the side of the trailer and look bad. My trailer has a rain deflector over the doorway.

Several years ago, we had a discussion of this topic, and it turned out that not all TMs have the rain deflector. We weren't able to determine whether the omission of the rain deflector was intended, or just sloppy assembly.

Here are a few more pics if the area cleaned up and then with some Dicor self leveling lap sealant. Hard to see in the pic but it definitely looks like there is a small hole or something there. Hopefully this stops the leaking.

Note: In the first picture my phone rotated the photo upsidedown. The awning is at the top of the photo and the shell on the bottom. You can kinda see a little protrusion in there much like the weep hole on the front side. I poured water directly in there and it came straight inside the TM. Hopefully i sealed it up good.

Brad, thanks for posting these pics. I discovered some minor mold on the front cabinet, curb side. It's been raining here, so I haven't been able to do much outside, but I was able to open a small gap where the cabinet meets the wall to allow the water to drain away and not get sucked up into the wood.
Your pictures and all of the other comments will let me narrow my inspection, but I will look over the whole roof. I had plans to do this, but this leak underlines the need for a yearly once over to prevent leaks.

Kid,

Yeah, I noticed the wood on the cabinet in that same corner was a little wet from our leak. Luckily don't see any mold. Caught the leak in the first rain, and now found the specific location of the leak during our 2nd rain + using the hose. Hoping that was the only time water got in.

I purchased a product called Permaseal for a bathroom project that headed another direction so I thought I'd try it on my Trail Manor. It's made for pool repairs and I special ordered it through a pool maintenance company, NOT CHEAP, but I'll tell you what. I striped every bit of caulk that had any sort of void, took my time and carefully applied a nice bead and one tube did all the repairs required. This stuff is the s..t.

We've had 2 2720SLs that had roof leaks (a 2001 and a 2006). The '01 model had an encounter with hurricane Matthew and we got the '06 shortly after. The approach that finally worked for me was more extreme than most suggestions and took about 4 hours to do the front and back. As mentioned by several others, caulking can separate from the strip that covers the roof seam. The seam under the strip is not sealed (at least not in 2006). I removed the center strip and as much caulking as possible and replaced it with a 6 inch wide strip of Eternabond. This product is made for repairing flat roofs and comes in a variety of lengths and widths. The sticky side has a thick gooey coating that sticks to anything it touches and doesn't want to release. So it requires some care and patience to apply. I learned to keep a small piece of the release backing handy for use when I need to grab the strip after removing the backing. I believe the roof seam is the primary source of leaks regardless of where the water appears inside.

I was having leaks too, and after reading these posts I was sure the center trim was where mine were coming from. My leak was manifesting itself in the front light fixture. I previously thought I had fixed the leak, but evidently this was a second leak. The first leak was coming around the front of the a/c shroud. There is a dent along the front of the a/c, and water was entering there. After re-caulking this, it fixed that leak, but the other remained. I then removed the center seal trim and replaced it with Eternabond. I haven't had a chance to test it yet, but I'm hopeful this is the solution.

After reading the discussion and seeing some of the questions, I shot a a before and after video to help others understand the issue in the future.

Well done video Ben! Very helpful in showing how you applied the Eternabond tape and new trim on top.

That's exactly what I did (eternabond between roof & trim) and no more leaks.
