Coating a TPO (vinyl) Roof

[TeryT]

Our TT is 13 years old. The vinyl TPO roof is still in decent shape, even though it sits out in the Phoenix heat (mostly) year round. Lately I've been wondering what to do when the vinyl starts going south.

From what info I've gathered, it looks like replacement would be in the $3-4k range for this trailer, which is 7.5' x 20'.

I then got excited because I read about people using "Liquid Rubber" (or Liquid Roof?) by ProGuard. Has anyone used this product on a TPO RV roof, and what has been the result? (somewhere I read that TPO roofs might require a special version of this product . . .)

Also, what is the coverage rate?

Thanks!

Thanks. So it looks like that product is just a few years old. Have you used it? It says it can keep the RV "up to 20 degrees cooler."

Does it have to be professionally applied, since it's a spray on?

Also, any idea of cost?

Rhino Lining RV Roof

I haven't used it but do a search, lots of previous discussion.
makes a permanent fix, not a band aid.

A previous quote said this about Rhino:

myself and several others have put rhino/linex etc. over plywood decking in toyhaulers and cargo trailers. We all have mixed feeling on it. Unlike in a truck bed, adhesion is not a strong point. while it's almost impossible to get these off a scuffed up metal base, over plywood adhesion is marginal. if it starts to come loose at an edge it is not hard at all to pull it off by hand. Thats after the installers claimed they have specific directions from rhino/linex etc. on how to install over plywood and it will stick as well as a truck bed.

yes it makes a good floor coating, easy to clean, great for toyhaulers, etc. but we all have to be careful about adhesion issues.

In all the cases it seemed to adhere real well for a few years, then after temp cycling, vibration etc. lifting at the corners

Oh that's interesting - Proguard advertises their "Liquid Roof" as the only liquid rubber product . . . hmmm

How long ago did you do your roof?
