What type of roof do I have

I just purchased my first RV a 2019 Miramar 34.2 and am trying to learn as much as possible. I would like to have on hand what is needed for maintenance and repairs . I would like to go on and get sealant but am not sure what I should get. It appears to be a rubber roof. What type of sealant should I use? I purchased EternaBond tape to have on hand if needed? Is Eternabond okay to use on this type of roof? Thanks for your help.

The roof is thermoplastic polyolefin (TPO). I use Dicor self-leveling sealant.

Thank you. That's what I thought but didn't want to use it and find out I was wrong.

Eternabond is safe to use on your TPO (thermoplastic polyolefin) roof. TPO is good material that requires little maintenance beyond visual inspections from time to time. Lots of info regarding maintenance if you look beyond the use as an RV roofing material and more with commercial applications which is where probably 95% of the TPO made ends up.

Regarding sealants I've replace 95% of the liquid based sealant on my roof with Eternabond tape and in the few areas that tape wasn't ideal I used EternaCaulk or Microsealant. The service life of all three is in excess of the 15 year warranty, they are safe for TPO and EPDM roofs and will probably outlast the coach under it.

Dicor sealants? All I can say is Dicor sealants are not your friend and will fail without warning causing a leak and the associated RV cancer that water damage is.
