Best Roof Material?
I am looking to up-grade my 5er. What roof material should I look for? EPDM, TPO or Fiberglass?
It costs me $300 a year to have the roof on my 5er cleaned and conditioned.
Do the rubber roofs flex where fiberglass will crack?

If your only choice is TPO or EPDM, go TPO.
I don't know if fiberglass tends to crack or not, but I definitely prefer TPO.

Why TPO?

It's not EPDM.
Not near as much upkeep on the roof material itself. EPDM sun rots and chalks where as TPO would eventually sun rot, but doesn't degrade the same. That's mainly it. And cheaper.
Both are pretty tough. The big thing is the actual installation of the roofing. I've seen Carriage's that use TPO but didn't get installed well, and were coming out from under the caps.
Also, the sealant used is a big deal. I am starting to prefer Sikaflex 715 over Dicor 501LSW.

I experienced a problem with the roof material on my 5th wheel slide-almost choked when I discovered the cost to replace the rubber roof. After reading an article in Trailer Life, about a motorhome company using spray on bed liner for their roofing material, I discovered Gator-Hyde bed liner already knows about this and has done many rv roofs.
They applied 3 coats on my slide and cost about 1/3 what a replacement rubber roof was quoted. I am very satisfied with it. IIRC should a problem develop they will correct it for free.
Disclaimer, i am only a satisfied customer and have no stake in any bed liner company, Gator-Hyde included.

I think Peterson started doing that as a standard choice?
But the reason it's cheaper is because all you have to do is clean and apply. No removal of roofing/decking/cleaning/prepping/sealing/etc. Just a quicker process.

What is it that costs so much? Can't see it. Remove acs, vents,etc, trim pull off old. cleanup and, glue, roll out, sealant, trim, cut out for acs, etc. caulk. Looks like a 2 man job for a day maybe two

How much time do you figure it would take you? Say 10 hrs for two people for two days, that's 40 hrs right?
What is your shops rate? This area is 95/hr.
And you CAN just glue right back down but all that old decking has old glue, dirt, dust, and pieces of wood sticking up ready to poke a hole in your new roofing. Gotta do something with that.

Shop wanted 5,000 to replace a floor on one of my slide outs. Replaced it myself in 2 days. Cost less than 200. Most of these shops are just riff offs. If I keep my unit long enough to replace roof I'll do that too.

Depends on what was in it and how big it was, but most floors we do are 2-3k range.
And of course it only cost you supplies without a mark up to yourself, your labor is free.
Did you pull the slide out?

I've seen a video of a company the removed existing rubber/TPO/EPDM roof and then coats the roof with a truck bed liner type of coating. Don't know longevity etc but sounds like a long term solution to roof replacement with only a wash needed for maintenance.

"Do the rubber roofs flex where fiberglass will crack?"....7 years and no cracks in my 2 piece fiberglass roof....costs me only time to clean annually.

Fiberglass should hold up the best and is the most puncture resisted. There is a company in Jacksonville FL that coats roofs with a 15-20 year product.
