I didn’t know how to determine the type of roofing. Thanks for the video! I haven’t cleaned the roof of my RV because I’ve heard a lot of rumours that one should not do that. Many people think it’s better to let the top build its “layer of protection” from all the stuff that falls onto it and the dust. I can understand it to some extent, but now the roof of my RV is just too dirty, and I want it clean before I put it to rest for the winter. That’s why I’m getting it to sparklewash.com
this week to clean it properly inside and out. I will tell the guys there that the roof is made of EPDM. They should know what to do with it.
