2000 Safari Class C Filon roof

[ranger378]

Hello All
There are so many roof products out there and they all seem wrong for me. What is the best way to treat or maintain a FILON roof?
The roof is attached around the edges and floats everywhere else. The roof is 16 years old. I'm afraid if I use the wrong stuff I will ruin it. I currently have no leaks but the roof is definitely in need of attention. Has anyone had success treating or coating their filon roof?
Thanks!

White marine epoxy. Right to the painted edge on the roll. A good clear coat on the painted rolled edge.

When that thin Filon starts showing lots of glass threads leaks will not be far behind.

No treatment needed for the material, it is what is the side walls for most RVs. You are looking at 10s of years, maybe 100s of years, before it weathers through, in the worst possible UV exposure conditions.

Wash the roof if the appearance bothers you, otherwise driving through rain cleans it.

What you need to take care of are the roof seams (sides and ends) and caulking for all the openings cut through the roof material. Edge seam maintenance needs care in particular, because if an edge lifts when traveling at high speed, the material is strong enough that the whole roof panel can lift, while roofing materials of lesser strength might just tear away locally.
