Rubber Roof Coating on Fiberglass roof

Thanks

As usual there is someone trying to make money off me for something I don't need. Thanks guys

Please only use products appropriate for RV use. Your RV has a fiberglass roof which really should never need any coating. The seams should use a self leveling caulk such as Dicor or eternabond - which were invented specifically for Rv's. Gaco is for houses. Your Rv is not a house. Houses do not have fiberglass roofs. it also contains petroleum which will cause a lot of issues to an RV finish and seams. Your wash guy does not seem to know what he is talking about when it comes to RV roofs.

I have to ask, do you have an issue with your roof? Is it cracked and/or leaking? A fiberglass roof is pretty much a forever kind of thing provided it's maintained and should never need to be covered with anything. Seems like everyone here is telling you the same thing, Dicor or eternabond on the seams and that's it. Your wash guy is trying to sell you something you don't need - or want. And if you still are skeptical, I have ocean front property in AZ for sale. Please PM me for details.

is it worth it, or leave as is ?

Thanks guys

Roofer says he is using silicone Gaco roof coating

Research Dicor Fiberglass Roof Sealant

Better to dust off and nuke the RV from orbit then to rubber coat that roof. But Eternabond on the endcap seams and to replace any of the self-leveling sealant that's aged out would be good.

Oh, I just did my roof not long ago...the endcap seams anyway, here's the write up...Roof work

I'm still able to work up there, for right now anyway. I have to do the side seams here soon (based on age and mileage) with Eternabond, and then replace the self-leveling goop someday. Right now the seals are still in excellent condition.

Don't do it. The coating will turn gray, flake off in pieces, get soft and leaves, pine needles, and stuff will stick to it and you will find it much harder to keep clean than the original fiberglass.

X2, also it will "bleed" down your coach when it gets older.

Or maybe he's hoping OP doesn't know what's he's talking about. ;)
