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.
