hi, new member 2001 class C chalet reseal the entire roof?

[leisure]

thank you for the add. I have been reading up on roof sealants and I am so confused on what to use . I have a 2001 class C chalet. We bought it used and I feel I should reseal the entire roof but unsure what the best to use is. I am pretty sure it is a fiberglass roof. any help would be great.

Thanks:

Here are a couple of useful links:

If things are in relatively bad condition, it's best to remove the fixture (vent, etc.), clean up all of the old sealant, re-seal and re-mount. I think you'll find that the most commonly used Winnebago part number will cross-reference to Manus Bond 75-AM sealant.

If things look to be in relatively good shape, you can clean things up and use Eternabond tape to cover all of the mounting flanges, extending over the edges to the roof. Personally this is what I chose to do. You'll find some nay-sayers but most of us who've done this are happy with it.

Whatever you choose to do, remember that gooping on globs of sealant over old sealant isn't going to do the job. You're never going to see gobs of sealant on a well-kept sailboat. In fact, you're going to be hard pressed to see any sealant since it's all between the fittings and the deck. Even the screw heads are shiny metal, the sealant is under them and in the screw hole.

And, although many will disagree, despite it's popularity, Dicor is not formulated for fiberglass roofs and is only specified by Winnebago for the rubber roofs on it's towables. Will it work, probably, but why not use what Winnebago specifies for its fiberglass roofs?

thank you for the great information. I am going to get it all stripped down and start from scratch. I think that is the best for me at this point. At least I know I got everything covered.(hopefully) wish me luck!!

Good idea and, if you add Eternabond, you shouldn't have to be concerned about it for years to come.

I agree with BobC. I used Eternabond on the roof of my first RV and it worked well for 12 years until I sold the RV. Did have to redo a place or two over the years, but for the most part, it's maintenance free.

I've also added Eternabond to my new to me Winnie roof. End caps and all along the roof edges for now, but eventually, I'll do all around the fixtures. For now, they're in really good condition. Not sure if the C models have the issue, but the Class A's are known to have the fiberglass roof rip apart or rip off if the caulking along the edges isn't keep in excellent condition.

Here's a link to my blog post about what I've done to my roofs, may or may not apply to your situation: Weatherizing my RV...
