spray on roof

seems to me thats a quick fix and cheap for them. BUT in 1979 we built a new home with spray on rubber something on the cement block, our house has never leaked a round the foundation.

Here is one company and some information. I don't know about on here, but there are many folks that have used the various products available on many of the manufacturers forums.

there is a recent thread about a product used instead of rhino lining. IMHO anything would be an upgrade from rubber EPDM.

Vortex is similar to Rhino and LineX spray on liners.

I've read posts on several RV forums where the Bed Liner products including Herculiner (DIY paint on/roll on) works very well to seal the roofs and provide a long term solution as a EPDM replacement.

You can get Herculiner at auto parts stores and online.

I like rvroof.com, but they are only in Florida. Next would be the Rhino liner (the RV elastomer type, not the bedliner, as the bedliner doesn't stretch/flex and isn't made to stop leaks.)

IMHO, anything is an upgrade from TPO/EPDM. I've even wondered about the 48 inch wide rolls of Eternabond for a roof.

Thank you all for your input and help! Is there anyone out there that has had one of these roofs installed?

I did not have a spray on roof installed, I used the roll on Herculiner, and it worked well. However it is very strong chemicals, and the smell was around for at least a week. I installed Herculiner. For a 30' roof, it took 5 gallons. $125 a gallon, and another $300 or so in supplies, chemical resistant gloves, suit, chemical respirator, ect.

So long as they aren't cheap at the seams I think it would be big step up for you. That stuff is tough.
