It details the common causes of wood damage on Newmars and shows a completed sprayed rv roof. Every authorized applicator is an RV roof repair specialist and knows how to handle the roof repair of all makes and models.
Some leaks aren’t noticeable
This coach owner did not know he had a leak until he went to have a new satellite dish installed. As you can see, instead of being nice and flat like a typical Newmar roof, this roof is wavy and has many dips that are holding water. In most cases with a Newmar, the roof will look like this and the owner hasn’t seen any water inside, so they aren’t aware that they even have a leak.

Water wicked into RV roof from cotton backing of vinyl roof.
The reason why a Newmar owner won’t see water inside has to do with how the roof is constructed. The top membrane has a cotton backing. If there is any place on the roof where the cotton is exposed it wicks in the water. Below the wood is a vinyl wallpaper. This backing stops the water from showing up inside. The end result is the wood swells and starts to rot. Here this damage started at the air conditioner and wicked out to the sides.
Here’s an example of the back side of the vinyl lining with the cotton backing. This is around a TV antenna, which is a common area for water to start to wick, along with here at the edge of a skylight where cracks can allow water to get through to that cotton backing.
This is the vinyl wallpaper on the back side of the wood that stops the water from showing up inside. As you can see, the insulation is dry but the wood has been rotting between the two layers and it just slowly keeps expanding until your whole roof is rotted. It just becomes wavy and this is what gives you that look.
Here’s another view of the vinyl that’s on the located on the backside of the wood that stops the water. And here’s the vinyl roof membrane with the rotted wood.
RV Roof repair is part of our process
The first step we take at FlexArmor authorized locations it’s starting to remove all the rotted wood, cutting out everything that’s bad, getting it all out of there, and making sure you have dry insulation. Your whole unit is wrapped in plastic to protect. We install all the new wood, and all your fixtures, and make sure that everything’s lined back up inside so that when we’re all done you’ve inside vents all work properly.

I own a 1975 GMC Eleganza motorcoach. It has an aluminium roof approximately 26 feet long.
It has a latter, roof pod, 2 ac units, 2 roof vents and antenna.
It also has seams front, rear and sides along the roof.
Will everything be removed to apply your product ? Not sure how this will be applied.
What is your estimate for my motorcoach ?
Jude: FlexArmor is sprayed on to your RV roof. The A/C units will be removed before application and then reinstalled. All the caulking will be removed since it will no longer be necessary.
