Sticky situation

The roof vents on this newly acquired RV became so sun damaged that they fell apart.
The previous (86 year old) owners’ son, instead of replacing the vents, covered them with black garbage bags and sealed them to the roof with duck tape. Nice.
When I removed the bags the tape was so old it had begun to fall apart, but it left a hard adhesive residue all around the vents. I figured who cares. But, my wife is determined that the roof be spotless. OCD, maybe?
What I need is a safe way to remove the adhesive. It’s thick and hard. I tried WD-40, but at this rate I’ll be done by 2023.
My question is, what is the roof on this unit made of? It is not rubber. At first I thought it was fiberglass, like my old Suncruiser. Now I’m not so sure. It’s hard, but seems to be covered with some sort of fabric.
Before I proceed any further I’d love some input. I don’t want to use any solvents or procedures that might damage the roof.
Thanks, in advance.

    I don’t give a rat about the roof. Who’s gonna see it? Some guy on a highway overpass??
    But, SWMBO has other ideas. Happy wife.......
    Can’t camp yet. Estate still running through the local court. It was in his name only.
    Already did the vents and shrouds. The easy part?
  • What is the model? That might give a clue to the roof.

    Don't start applying chemicals or mechanical removal efforts until you determine the material. You may do more harm than just leaving it alone.
  • New vent covers and apply some forgetaboutit. Tell DW all is ship shape and weather tight. Time to go camping.
  • Fiberglass, when long worn and weather/sun deteriorated will look like a fabric. I'd go with mineral spirits, as previously suggested.
  • 1.) Yes, I used that process (eraser wheel) to remove the goo around one of the vents. I had used it prior to redo all the graphics on my ‘96 Suncruiser. Very familiar with the process.
    It seemed to work fine here, too. A bit hard on the hands is all. But, then I noticed that a small spot of the roof seemed to have wrinkled, as if the heat had loosed the adhesive on some sort of fabric? I finished, being sure not to abrade any one section very long.
    So, if there is a roof covering of some sort I need to be mindful of, I’d like to have that verified before I go any further.

    2.) I may run to Home Depot and get some Caulk-Be-Gone. Worth a shot. Seems less dangerous than stuff with a Xylene or Acetone base. I have a lot of both, but was afraid of damaging the roof integrity.

  • You could try a eraser wheel (from Amazon). I used one to get decals off my new to me boat fiberglass. It did great without any damage to the boat.
  • Mineral spirits remove residues cheaply, but be sure to test for any impact to your roof.
