Roof Leak - 2019 Aspire

[Darrin77]

Roof leak in yesterday's rain storm here in CT.

2019 Aspire 42 DEQ

Water was coming through the front light fixture in the living room. Not terrible!

Nothing like climbing a ladder in pouring rain and 45mph winds!

I got to it quickly and took down the light fixture. I had to make the 2" diameter hole (that was only there to feed to wires to the light fixture) about 10 inches square to access and remove more wet insulation, check for further moisture, and direct a fan to blow air into the space to dry it out. It helped to pull down 7 recessed ceiling lights so the air had room to exit.

I moved the coach so I was on just enough of a slope to allow water to roll off the passenger side and slightly toward the rear of the coach.


My question is about the roof exterior and next steps. I just purchased this darn thing (I love it, btw) one month ago, and it looks like all the sealant is good. I'll check the front AC to see if drains are clear.

Any other places I should be inspecting? I know I can call Entegra for this next question... what's the best prep process and the sealant Entegra recommends if I need to lay down additional sealing over existing sealant?

My gut says soft scrub brush, water, Dawn, some diluted Simple Green, and a final clean with microfiber cloth and denatured alcohol.

Thoughts?

Thx.

check all things with sealant.
dont look at them finger them to see if they are loose all around.
Nuflex 311 is the sealant to use , not easy to find in black, check entegra parts for price, Winnebago also use it, i have been using white was easier to find.

my last leak was the vents and wire caps, sealant looked good but the sealant was not adhered to the sides letting water in.

All good stuff! Thank you.

I've got a white roof on my coach.

Your leak sounds like it's near the front of the coach, the marker lights there have been a common leak point also. The newer ones like yours seem to be less prone to the issue, but on my 2013 I have had them leak not necessarily from where they are bedded but from the fixture itself, water would get behind the lens and flow down the wiring.

The NuFlex 311 is a flowable silicone and Entegra started using it (in lieu of Dicor) around 2016 or so. My coach roof is white also but Entegra used black NuFlex.

Professional leak testers use high volume fans to create a positive air pressure inside the rig then spray the suspect leak areas outside with soapy water and look for bubbles. Google around for assorted DIY options.

Fortunately I've not had any serious leaks (yet) but often wondered if running the maxair roof fans in reverse (blowing inward) at full blast would create enough pressure to find a leak that way.

Although you have a leak to find, we tend to level our coaches too much. When rain is predicted, raise the front a little and the door side as well. Keep the water flowing off the back and away from the door.
