Water leak around Dish wires

Interesting timing. :). I have 2 50' rolls already on the way. I have a 35' TT at the deer lease that I'm going to seal as well. Not sure what else I will use 100' of Eternabond on, LOL.

My rooftop sat cables are protected and sealed where they penetrate the roof with a Winwgard cable entry plate with grooves in it for each wire. When I added additional cables for the cell and sat radio antennas, I just ran a bead of Dicor in each groove and a bead where the plate seats on the roof. After screwing the plate down, I sealed the screw heads and the plate edges.

This is the plate I have, but they also have them with different numbers of grooves:

Thanks, Dutch. That is a great design & should fix my issue. I will have to check into this.

I thought I had the same issue a few years ago. I tried to fix it for 2 years until I discovered a pinhole in center of the caulk around the roof mounted spot light. Water wil always find the path of least resistance ......

Thanks, everyone.
I use Dicor and know it is the cables because I've seen it. I fixed it once before & that lasted a couple years. Since I have 2 cables going through the hole, I'm thinking it's tough to get a good seal between the 2 & it wicks between them. I really think it has to do with the darn Texas heat and age of the Dicor also & I just need to replace it more often. I had an RV repair shop owner tell me that caulking should be replaced every year if the RV sits in the Texas sun. Not a bad idea to protect our baby!!

Here is what I'm building to protect against that sun & I'm going to replace all caulking here in the next few months that I didn't get to this past fall. :)

Could be the leak is from another source and just running down those cables. I would get a dealer to perform a pressure test.

clean the area and use Dicor self leveling caulk and you shouldn't have any more problems. If you have used other types of caulk in that area remove it first. You really don't need any electrical boxes on your roof to seal it

What are you using for caulk?

The best I have done here which is usually on the side of the trailer and not on the flat roof is to mount one of these PVC electrical junction boxes that has a weather tight lid on it. Drill out a large hole in bottom of the junction box. You would want this to come out on the inside into a ceiling mounted cabinet etc. You actually mounted another PVC box here on the inside and continue your PVC FLEX hose with your RG cables inside to where ever they are suppose to go to... Then use PVC flex lines to gain entrance to the junction box from the side holes. All wiring is enclosed now and sealed from the weather to give tight seal against water leaks. All of this is extra work but will solve your water leak problem.

I do this same idea routing all of Battery DC cabling all over my trailer. Running FLEX PVC is best for the inside runs and maybe solid PVC lines for the outside runs for appearance...

LOWES makes all different types of these PVC junction boxes with multiple ports. I really don't have any problems here in our sun from UV's but that may be a problem for high sun areas.
