We are looking at buying a Forest River Lexington motorhome. We have noticed that some companies list a TPO roof. Can anyone tell me what type of roof this is and how it compares to the fiberglass?

Thanks.

I don't consider forest river to be a "premium" builder and fiberglass is superior to TPO which of course is at least acceptable, in contrast with rubber.

wide open statement, how about some specifics?
Model, reason for blanket statement including where the fault was, dealership or FR.
Did you buy new or after it was abused?

I would not own another rubber roof RV. I have had a Holiday Rambler with aluminum roof and that was a verey good roof. I now have TPO roof and while better than rubber, it ain't fiberglas or aluminum. Winnebage had some problems with fibreglas roof blowing off at one point.

A key reason we chose Winnebago when we bought our new motorhome last summer was because of the fiberglass roof. My travel trailer had a TPO roof. Fiberglass is easier to keep clean so less black streaks on the side of your MH.
I worked in the RV service business for a couple of years, and while I can't give you specifics I would not buy any Forest River product. Mostly its fit and finish issues.
While some might be able to overlook seemingly "minor" issues like this, it's not a minor issue when fit and finish problems include cabinets not securely attached to the walls and ceiling, or exterior moldings poorly attached allowing water leaks. Perhaps Forest River quality control has improved over the last couple of years. I'm sure you'll find Forest River owners who are completely satisfied with their unit.

I had a Holiday Rambler with an aluminum roof and I would'nt have another one. The roof developed small pin holes and started leaking. The HR salesman I talked to said that was common with aluminum roofs after a few years and the only way to fix it is replace the roof.

My 1988 Winnebago has an aluminum roof. No pinholes or any other problems.

All roof problems I have had over 20+ years of ownership have been water leaks due to aging of seals along the edges and skylight. For this reason, I want my next motorhome (if the Winnie ever wears out) to have a fiberglass roof that overlaps down the sides (and ideally overlaps or is fiberglass-bonded to the front and rear caps too)

I've looked as some rubber roofed coaches in dealer lots, and they look awful to me. Serious wrinkles and bubbles where they round the edge along the sides. And these were brand new coaches.

I also looked at the Forest River Lexington. The fiberglass roof is superior to the TPO roof and it's available in the non-GTS model. The TPO roof is a good product and will give you many years of trouble free service. Repairing a TPO roof is not an expensive project. What it comes down to is affordability.
When you look at the Lexi roof you will see more seams then other manufacturer have and that was a problem for me. Since the competition was the same price and equal or better quality, I went with the other brand. Only time will prove me right or not-right. (I'm never wrong)

Problem with the TPO is you are supposed to r&r the caulk every 2 to 3 years. Very few folks do it. Which is fine, but then they act surprised when it leaks after 5 years.
