My TPO Roof (thermopolyolifin) is about as good today as the day I bought the camper 13 years ago, in fact I can’t even see a difference…When not in use, the truck camper has been ‘mostly’ (but not always) covered, yet gets used regularly, I’d estimate that between two different vehicles it has about 185k miles on it, including plenty of NV high desert camping…So it’s not quite clear to me why one would seek to avoid TPO??

3 tons Unfamiliarity, and not enough knowledge on the subject.

First thanks to IAMICHABOD that link told me I have an EPDM roof - Now the follow up question - what adhesive is the correct one to repair a section of the roof?
Thanks!

How big of a section are you needing to repair? If it's a tear, get Eternabond tape. If it's a small hole, the I would use Eternabond and then Dicor self levelling.

I got a pinhole last october and by the time I had found out about the hole, I had a bubble (like the top of a 747) of the 5er.
Since the Trailer is 12 years old - for the time being i just want to reattach the existing roof (except for the single hole - the roof is in decent shape) the existing EPDM back the wood substrate.
As Doug Pointed out in another email - because of the age of the 5er - If I was going to do it right, I would replace the entire roof - but for the time being I need to seal it up so I can use it for the season.
So my question is: What is the correct type of adhesive to use to attach epdm to the wood substrate of the roof?

The ONLY CORRECT way to attach a TPO/EPDM roof to the roof is to pull the OLD off and redeck(overlay) the existing wood deck. Then use EPDM/TPO approved adhesive. If you attempt to install new TPO/EPDM over the existing wood after removing the old, the new glue will not adhere correctly to the old decking and you will have hundreds of little bumps under the new roof material. Below is the link for the adhesive. Doug
PS, Use the link and use that glue to do your repair. What I do for your type is to cut out the square area and remove the rubber. Cut a slightly larger piece of rubber and glue in place and then use Eternabond around the perimeter.

https://dicorproducts.com/product/water-based-bonding-adhesive/ THAT is why I like reading your posts. As simple as it is I wouldn't have thought of doing it that way but it would definitely work better than what I would have done.
I would have cut a slit at the bubbled part, laid it down flat and put Eternabond on the cut part to seal it. I still wouldn't have the repair glued down doing that, even though it would be sealed.
I am also a lousy carpenter. ![[emoticon]](https://forums.motorhome.com/sharedcontent/cfb/images/wink.gif "wink")

Doug,
As always, thank you so much for the guidance and advice.
I was thinking exactly the same idea for resealing it after it was reattached.
Eternabond, and once it's all together (with new wood underneath) I was going to put one of the roof coatings (hengs, henry, etc) - of course, not knowing which one to use, If I'm in for an inch, I'm in for a mile. I'll ask.
Which has been the best performing coating that you've used?
Thanks!
josh
