JJ,
Thank you for your research on this issue. I do live in a colder climate (Michigan) so my roof has not seen the extreme high temperatures of its lifetime. I make sure if and when I replace my roof to get the latest spec TPO material.

And IMO, TPO would be my last choice for my trailer…
there has been plenty written about the shortcomings of TPO… its strong point is its seams that shouldn’t be a problem for RV’s that don’t have seams to begin with… since it last reformulation (2010 or 2011) the industry has been extremely silent without touting that things have been finally resolved… is that a good sign or are they hiding new concerns…
it’s popularity seems to be more along the lines of cost, not quality…
“Longevity
By far the most important aspect that will determine the longevity of a single ply roofing membrane is the method by which the overlapping seams have been attached together. Permanently attached seams are the safest solution, and improper attachment can be the cause of 99% of leaks.
It is difficult to determine the longevity of TPO roofing membranes for a couple of reasons. First, this is a fairly new roofing product, there are no TPO membranes in the US today that are older than 15 years. Second, TPO membranes continue to be an experimental products- they are all in their 2nd, 3rd and in some cases 4th generation of formulations, so it is not possible to definitively say how long any of these will last. Moreover, many TPO products have been pulled off the market in the past both for seam and material failures.”
“Durability
An EPDM roof has a solid reputation for durability. Made of rubber compound, EPDM roofs have been on the market for decades- having properly tapered seams and detailed flashings, an EPDM roof will last up to 25 years. It is recognized in the industry as a dependable roofing material that offers resistance against ultraviolet light, ozone, oxidants and severe weather conditions. An EPDM membrane will also perform better than TPO in colder climates.”
