Greetings !
I have a rubber roof question. I have a 2000 Jayco Qwest 294 J and of course have the rubber roof which is in surprisingly good shape. The previous owner kept up with the seams. My question is is it a Dicor or an Alpha roof ? The newer Jayco's seem to use the Alpha not sure about the older ones. The products to take care of these roofs tend to be different in some cases. I tried contacting Jayco but got no response, probably because it is an older unit and their information doesn't go back that far. My owners manual just states I have a rubber roof. No much help there,LOL Thanks
I'm not 100% sure but I think they say if the underside is black, its EPDM (alpha), if not it's TPO (Dicor). You can check the underside by removing a vent to see the underside of the roofing material. Actually the newer jayco's use diflex II roofing which is a Dicor TPO product.
I doubt its TPO due to the age, I was told Alpha and Dicor both made EPDM roofs. The Alpha has more of a beige color while the Dicor tends to be more white. Problem is on an older unit like mine with UV damage it hard to tell color. Also who knows it may have been recoated, I know I did my wilderness twice in it's lifetime. Issue is the coatings and some of the sealers I have been reading are not compatible with the Alpha roofs, but work with Dicor.
