TPO vs Fiberglass Roofs good-bad-ugly

We are trying to compare the two roof types. Would like to hear from owners of both good and bad.

I believe all higher end coaches have either fiberglass or aluminum.

We have had both in our 40+ years of RVing, and realy have no preference. At least not one that would make the roof a deal breaker on purchase.

I had fiberglass that was an extra cost option and I had no problems or complaints.

I wanted the strength to prevent tears and holes from tree branches.

Most feel fiberglass is the better choice all around. We also have had both, and did put a rip on our TPO from a tree branch that would not have affected a fiberglass roof at all.

I have a 25 year old rig with fiberglass and I would bet the way it looks its never had a coat of any additional material. And while it has fibers showing and makes your pants itch if you crawl on it. I only has problems at the seams near the edges of the roof where it caps the siding. And there I added Eatarbon tape...

So what I'm hearing the TPO roof system is a good choice for a entry level coach.

Smile TPO vs Fiberglass Roofs

I have had both. I much prefer fibreglass for the reasons already stated. I would caution you to really have the roof inspected if you are considering a used coach with a rubber roof. My experience with rubber was not a good one therefore for me I will only look at fibreglass. I have only owned 3 coaches , 1 rubber and 2 fiberglass.

TPO is not EPDM - totally different materials; therefore, a TPO membrane is not a "rubber roof". The TPO roof on our 5th wheel (see signature) has given us no problems whatsoever in almost 10 years of ownership, doesn't chalk or streak and still looks about like it did when new. No complaints at all here with TPO.

Ditto what RustyJC said. TPO is a completely different roof from EPDM. I have TPO and like it. It's white so it reflects heat well, and is sort of like a hard plastic. Easy to clean and doesn't streak down the sides of my MH. It's one piece and I've completely sealed around the edges with Eternabond. Pretty maintenance free so far.

I had the same question. If you google tpo vs fiberglass rv roof there is plenty of info. When I read it, at the time, it was about a even for supporters. I have had TPO for >10 years, 2 coaches and have been very happy.
