Water Leaking Over Window and In Lights

Good Evening,

I am glad I found this site, as it appears tough to find good info online about trailers. We have a 2017 154BH JayFlight purchased new. We are first time owners of a TT We live in Washington State and keep the trailer covered in the winter.

This spring, I found a few dripping leaks above the front window on the inside. It was easy to tell the gasket/seal behind the window was worn out (no caulking was used). That was an easy fix. Well, a few days ago, I noticed more water coming in from behind the cabinets on the front above the window. After some inspection, I noticed the front running lights on top (led assembly) were not screwed in fully and the cheap foam gasket was drenched. Furthermore, the hole inside was very wet.

First, should I simply caulk around all the lights and Windows as Jayco didn't/does not do that? Second, repair shop (way too expensive), said I need touch up sealant on the roof and there is a small hole. Any experience with Eternabond Tape for the hole? And, I am struggling to find if I have TPO or EPDM (can't find it in the manual) to use the appropriate roof sealant. Thanks you!

In the meantime, you might want to use the tongue jack to raise the front of the trailer just to try and divert some of the water to the rear.

Using the search function in the gold bar above you can find tons of Etearnabond information and Dicor self leveling caulk info.



Re the front window, mine leaked with every heavy rain. You could literately see outside through the corners. Use Dicor there and finally got it stopped. Caution, not easy to apply as extremely short working time (or no working time!). I went over every light, window and door after that in case of an undetected leak into the frame.



On roof, Etearnabond seems to be a fix for all rubber roofs if applied correctly.

Thanks for the help and direction to search bar. What about over external lights? Seems to me they are just poorly installed and not sealed.

On external lights there are two paths or belt and suspenders.

Take them off and fill the holes with sealant before putting in the screws that hold them on.
Caulk around them to prevent water from getting in.


Or both.

I've used Butyl putty tape (RV dealers have it) as a clearance light backing seal then trim off excess...., then apply a thin bead of silicone caulk alone the top edge of the clearance light/putty tape.
