RV Roof Repair Qustion

A friend call me today, with a question concerning the roof on his RV, he explained that he thinks he has a fiberglass roof. He explains that the roof looks like it is covered with cloth, that has tears in it. He wants to know what he can put on the roof to seal it, and I am at a loss to know what exactly is this cloth looking covering is, so my question is, does any one know what kind of roof he has and what would be best to seal the roof?

Thanks

Johnnie

  • The RV is a 1997 Fleetwood Flair Motorhome, he has sent one pic, which I will post now. I have asked him to send a more detailed picture of the roof, which I will post.

    Below is a more detailed picture of the roof, looks like a rubber roof to me. So what is best to use on this type of roof for repair. He would like to cover the entire roof with some type of sealer.

  • Thanks so much for your replies to this issue, the information requested is forth coming, which I will post. My friend Rusty and I thank you'all again for your help.

  • My guess is TPO also but what generation is anybodys guess… there are a least 5 reformulations of TPO…

    if the trailer is newer and has TPO the sealants needed may be different than with earlier versions… according to Dicor, Dicor Lap Sealant can be used with all EPDM (rubber)… but if your RV has TPO roofing and it was built after 2010, you may need to use the Dicor Ultra Sealant System instead of Lap Sealant to avoid disfiguration and bloating of the roofing that may result from using Lap Sealant….
  • My money is on it being an EPDM (rubber) roof. Fiberglas looks like plastic or Fiberglas, not something with tears in it. Year, make, model would be a great help.

    We'd have to see pics and know for sure if it's fiberglass or rubber and how extensive the damage is. It's possible that Eternabond tape might work if it's not too bad.
