RV roof & window water leak repair

[don meyer]

Goodmorning, We recently bought a user Hi-Low trailer. We are very happy with the construction, but it shows signs of water leaks.

I removed the worst window & removed the old caulking from the molding where roof & side panels meet.

I caulked these areas with ProflexRV caulk.

I should of joined the forum sooner To ask, but is this a good caulk to use?

Thanks Don

I have never heard of Proflex RV caulk so I did a search here on the forum. Here is a link to one of the 4 other threads that mention it....
I hope it helps...
Oh..I should welcome you to iRV2!

Actually first of all you need to use the rope type caulk for the windows. It normally comes in a 25 or 50 foot roll and you put it completely around the window before install. Then after install and snugged up clean up the excess and use a NON silicone type caulk around the top and two sides. Done deal. Your roof is probably covered with a Dicor rubber type material? So get yourself the proper stuff. Dicor lap seal is probably one of the better.

My roof is alum & the sides are fiberglass. Proflexrv caulk I thought was made for this???
The windows were installed at the factory with the a soft puddy type
caulk, probably the rope tape discussed above, so maybe I used the wrong stuff on the window.
Does anyone know if the Proflexrv caulk(sold at Camping world)will work on windows or should I remove the window & re-do with the rope type soft caulk?

Please help, I have 2 days to go before rain.

Thanks, Don

Take the windows out and redo it. Yes I was talking about the gray putty tape. Like I said generally it is sold in 25 or 50 foot rolls. Years ago I bought a 50 foot roll and used it all around one of my old trailers resealing the windows. Easy to work with and it is inexpensive. This is the only permanent fix IMHO.
