would ya/could ya use Flexseal on the roof??

[mcal63775]

Having just watched the commercial for the product called Flexseal, a thick liquid that turns into a "flexible rubber sealant". It can be ordered in black or white. I am seriously thinking about putting it on my rubber roof which needs, in my opinion, replaced. A couple of coats rolled on the roof with a paint roller and brushed on along the edges. Do you think it is a good idea? Ideas? Pros and cons? 33 foot Coachmen with two AC units on top.

It isn't cheap, but a lot less than a destroyed RV after a rubber roof leak that you don't find until your rig is destroyed.

After experiencing a rubber roof failure that fortunately I caught before any major damage occurred, I consider a new roof just the cost necessary to build an RV roof correctly the first time. If I were buying a new RV today I would have the roof sprayed before I ever moved into it or even used it. No more rubber membrane to fail, caulking seams to fail, etc. No more getting on the roof a couple of times a year to try to see where the next leak will come from.

The cost of the RV Flex Armor roof can be slightly different at each of their install locations. I had mine done in Jackson, MS and it was $170.00/linear foot. Not cheap I agree, but worth every cent to me.

I can now hear the TV when it is raining because of the extra roof thickness and my a/c's actually cycle on/off even in Florida on a 90 degree day.

If you do a search of the MSDS sheet on Flexseal, you will find that it contains a significant amount of petroleum products in it. Anything that would not be affected by petroleum or asphalt products would be fine for using Flexseal.

If you have a fiberglass roof Dicor Self Leveling Caulk works really well. Interesting comments on the flexseal, I also bought a can of that when it first came out but never used it on anything!

Fiberglass or aluminum, maybe. A soft material roof, never. I have concerns about material compatibility.

I receintly purchased a can of Flexseal, and then ended up not using it. So now I am in the process of fixing up my tool shed, replacing rotten wood, missing shingles and new paint. I used over a dozen tubes of old caulking sealers on it, then ran out. I didn't want to purchase anything new, because I've simply got too much old stuff laying around from previous projects. So I decided to give the Flexseal a try. Well, it did spray and closed up cracks, but almost as fast as it dried, it was subject to pealing right off. I ended up slapping some paint on top of it right away to seal the Flexseal, so it wouldn't peal off any more. It worked, and under that left over spray paint is a rubber protection, sealing those cracks (until the paint chips off).

So my "shed of many colors" fix is finished, and I started painting it all one color tonight. So, it's now rebuilt and sealed pretty good.

But on the roof of my travel trailer? After what I just experienced with it ... NEVER!

For the OP. It is worth it to purchase a single can and experiment with it on various surfaces and then judge for yourself. Lowe's now sells it in the paint section. That's where I got my can.

Will I use it again? Probably not!

I used it on a couple of corner pieces that have cracked. It needs a rough surface to stick. Seems to work OK in the cracks I wanted it in though. Will peel off irrespective of other issues it might have.

and if any moisture is trapped underneath it will bubble up when the water turns to steam on a hot day. Even if you use white

This has been discussed on the forum several times. Most agree, it is not a good idea to use Flex Seal on rubber roofs.

I believe it's a petroleum based product that is not good for the roof.
