The EPDM (I think it is EPDM) roof on my 2004 Outfitter TC is coming unglued from whatever is underneath it. I see several areas that are lifting up. None are raised more than 1/4" but they show up....
Yes keep a close eye on it and take occasional photos with your cell phone to see if it is getting worse. See no need for drastic action at this point but make sure no gaps or teares around the roof edges and double check the edge caulking that it is still good condition. I had a few of those on my roof for years with no adverse effects but I also recoated by roof with fresh EDPM once a year. It was fun in early morning cool hours. Cheers
