Patching a PPO rubber roof?

Totally incorrect according to the Whole Building Design Guide which is the resource used by architects.

"Thermoplastic polyolefin (TPO)

TPO is the latest thermoplastic membrane introduced into the marketplace....It is formulated from polypropylene, polyethylene or other olefinic materials...."

"Ethylene propylene diene monomer or terpolymer (EPDM):

EPDM is a synthetic rubber sheet...."

TPO seams are heat welded, EPDM seams are taped or glued. They are different materials. TPO is more expensive and a superior product.

I run a rubber roof for years, just carried a 4" roll of eternabond w/ me.
IMO, there would never be a reason to replace a rubber roof,....not as long as a 12" and 24" roll of eternabond is available.

What is a PPO rubber roof? There is TPO which is more like vinyl and EPDM which is rubber.

eternabond, done deal

Another vote for Eternabond. Great stuff.

Eternabond tape will take care of it.

I put a dicor patch on the roof in 2004. It was still on and in good shape in 2012 when I traded the trailer.

Moved from Forum Technical Support

I would suggest Eternabond tape. Once its stuck it wont come loose.
