what type roof do I have?

Recently bought a Keystone Hideout 27DBS and I want to ensure never any leaks! I got on the roof while covering with my adco cover and there is two tiny spots where the Dicor or similar sealant has settled a bit. I could probably not do anything and it would be okay, but I want to hit it with the correct sealant.
My question is do I have the TPO OR EPDM roof? I can describe my roof as a plastic like roof, bright white, an not nearly as slippery as my old rubber like roof on my old Wildwood.
When I rub my hand across rough its not a real smooth texture.
I emailed Keystone to ask them what type of roof do I have and what type of lap sealant should I use and they weren't helpful at all!
My owners manual basically said to just use a sealant to maintain the roof.

    thanks to path1 I watched the following video...

    I then determined I have TPO roof. The local rv store sold me "alpha" self leveling lap sealant saying its the best on the market and better than Dicor. The dicor scared me away and I bought into the more expensive Aplha sealant, because the Dicor tube said NOT compatible with all TPO roofs. Also, the example test spots at the rv store made it look like to me the manufacture used Alpha lap sealant the first time around and not Dicor. It seems after curing Alpha is more flexible ad soft than Dicor, and whats on my roof now seems flexible and soft.
    Any one know a specific type of cleaning agent I need to use on my TPO Roof? And also a maybe a agent I need to wash with a couple times a year?

    It should have said what kind of roof you have along with everything else in or on the TT in the packets of information you should have gotten from the dealer when you picked up the trailer. They usually give you all that along with the different warranties for the appliances, etc. I still have ours as they come in handy sometimes.

    Fwiw, I have an Alpha Ply roof which Alpha considers a TPO roof. I spoke with Alpha and was told Dicor products were fine to use for sealing.

    based on you description, you most likely have TPO roof…
    you could also have one of Alpha system roofs like, Alpha-Ply Roof Membrane or the Superflex Roof Membrane …
    you might want to write to them to see what differences they are… I believe they are different formulations of TOP and may have different maintaining and repair materials…

    Sure sounds like TPO to me. TPO is typically slightly rough textured and EDPM is always smooth as far as I know.
