Just for anyone's FYI

I have a Alpha brand TPO roof ( it has a textured finish and not smooth) i have been contemplating sealing it because it's 12 years old and i don't want leaks. I found a product called Superior RV Roof and purchased it last year. While reading the small print on the 5 gallon can i saw "not to be used on Alpha brand EPDM roofs" i called the manufacturer and explained that I had a Alpha brand TPO roof and was assured that TPO roof was fine. So just make sure you read the fine print guys and gals! I just put some on a small test patch and it is thick and seems to "skin" over pretty fast. One of the things that impressed me about the product is that it is one part, so no mixing, and it can handle ponding water, and a second coat can be applied up to a week after the first and once the newly applied coating is put down, if it rains within a few hours, the coating is not affected

    Well just got done coating the entire roof, went on smooth no problems at all. Only used about 2 1/2 gallons of the 5 gallons i bought. More than enough to do a second coat next week. Well.... There was one problem, i was in almost direct sunlight and didn't have my sunglasses on.... Darn near went snowblind!

    I thought the one and only good thing about TPO was that recoating isn't necessary.

    Not sure where you go that particular tidbit, but all roofing material degrades under the constant attack of UV rays. The best TPO warranty I could find (on a commercial building) was 25 years.

    The vinyl/plastic of a TPO membrane isn't supposed to deteriorate like EPDM (rubber).

    No one claimed it did. But just because it deteriorates differently doesn't mean it doesn't deteriorate. Nothing is forever. I couldn't find the Alpha warranty, but Dicor's Diflex II TPO has a 12 year warranty (material only, doesn't cover any consequential damage), so the OP's 12 year refresh seems reasonable.

    My Airstream roof comes close.

    You are correct, i did want to refresh the membrane. I called Jayco when I got the RV to confirm the type of roof and manufacturer. They confirmed it was an Alpha TPO roof and that it had a 12 year warranty. But only to the original owner...... Not me.... So that is why I wanted to put the coating on
