EPDM or TPO roof

[hldurham]

I have a 2004 Forest River Wildwood T26FK model (California manufactured) Does anyone know what type of rubber is on this model?Just doing some maintenance on the roof. I bought the TT used so don't know much about roofing. some of the Dicor is developing hairline cracks so I want to make sure I know which material I have. Any input would be appreciated.

Epdm is rubber.
Tpo is poly plastic. "Thermoplastic polyolefin"

Epdm is glued and taped
Tpo is heat welded

If my epdm roof ever needs replaced it will defiantly be tpo instead of epdm

http://http://www.rtnroofing.com/articles/511.htm tpo shrinks and cracks a worn out epdm roof if coated with the Safe-t-plex elastomeric acrylic rv roof system along with the tape-kote 4" fiber backed seam tape you will have a maintenance free rv roof for 20+ years.
