Fiberglass as a replacement for EPDM

Thanks for all of the feedback. I guess I did not think how much the 3/8" plywood flexes between roof trusses (16" O.C. or 24" O.C.). Doing more than 2 layers would be cost prohibitive.

Several RV dealers that I contacted mentioned a product called Peel & Seal.. The dealers did not want to order standard RV rolled roofing..

It is a sticky rubber backed material with a thin layer of aluminum foil on the top.

This product looks very promising !

This is the second year on this material and so far has fixed my leaking issues...

We need an annual report ! I would say if it lasts 10+ years, it is a winner !

If I was going to ever face redoing my roof again, it WILL be a one piece sheet of heavy aluminum. Lasts much longer than an rubber or soft roofing.

"Heavy" aluminum ? While I do think aluminum with as few seams as possible is probably the best solution, material cost and installation would be very challenging !

I covered my TC plywood roof with aluminum sheet 0.025 gage (25 mil/22 gauge ?). Used very expensive Evercoat tube epoxy @ 70$ a piece, to glue all edges down. To save money, I also used exterior carpet adhesive in the middle of these panels. Still dam expensive but it should last forever.

Do you recall what type of aluminum it was (60xx or 52xx or ????)

THESE guys used to sell .050 thickness rolled aluminum roofing cut to the length you specified..

They do still sell roofing aluminum but looks like you will have seams in order to get it done.

The biggest issue with aluminum is the shipping, must ship truck freight and with truck freight unless you have a dock and a forklift unloading might be pretty darn tricky, not to mention the higher shipping cost involved.

Installing aluminum is easier than laying down a rubber roof once you get the roll on the roof. Nothing to glue, just roll out, center, roll on the putty, then fold down the edges over the wall siding, reinstall the trim..

While were I work does have a dock and forklifts, the company sort of frowns on employees having large things sent there and local RV dealers did not want to get involved with special ordering rolled aluminum..

I would have kept the rolled aluminum on my trailer but the previous owner decided to use a air nailer during a failed attempt to rebuild the trailer.. Thousands of neat little pin holes where they shot brad nails through the roof..

If the peal and seal gives me any trouble, I WILL be checking with a local custom horse trailer manufacturer to see if they would be willing to get me what I seek..

That rubber roofing is simply a short lived cheap product, meant for the average short life of most RVs which is 10-15 yrs.. Aluminum if nobody does anything stupid like sending brad nails through it can easily last 30 or more years..
