EPDM or TPO roof

[swaldow]

I need to repair the seals on the roof of my 2013 Salem 26Tbud but I don't know what type of roof it has. I've looked all over the internet and can't find anything that tells me exactly what it is. I want to make sure I purchase the correct sealer. Does anyone have this information? Thank you in advance.

If you drop a vent trim and look at the back of the material EPDM will be black. Not so with TPO. I think this is correct.

This is correct, drop the trim off to be sure, take no one's word, it could be disasters for you and have to replace the whole thing.
