Hello,

I've had my '06 29' Chalet (which is the rental version of the Outlook) for a couple years now. It came without an awning or ladder so I was always under the impression that it had a rubber roof since it is a base model. I was almost to the point of ordering and applying rubber roof sealant until I decided to replace the useless OEM antenna (looks like a flying saucer) with a King Jack antenna, which btw works well.

After removing the old antenna and cleaning that area I took a closer look and saw that the roof is fiberglass. I then got my buffer and some fiberglass buffing compound and cleaned the area. Next I used a 2 1/4" hole saw to cut the hole for the new antenna. The composition of the roof from top to bottom is as follows, fiberglass laminated to thin lauan laminated to aluminum laminated to a couple inches of Styrofoam laminated to thin lauan with headliner material glued to that.

I consider it good news that the roof is fiberglass and besides being a little bit dirty, appears to be in excellent condition. I do have a couple questions since I'm not an expert on this type of roof. Am I correct in assuming this is better roof than the rubber roof? Is there any maintenance to be performed on a fiberglass roof besides keeping an eye on the self leveling sealant? Is it common to find fiberglass roofs Minis of this vintage?

Thanks

The only drawback to the Winnebago fiberglass roof is the joint between the roof and side rail. The 'caulk' is also the adhesive that holds the fiberglass in place. If not properly maintained, a wind or driving the RV can cause the roof to peel off. Use the search box at the top of the page with the Google logo to find other threads on this fiberglass roof issue.

Thanks, I did find some conversations on fiberglass roofs. What is a good caulk to use on the side rail joint?

I would go to the Winnebago website and look under the "Resources" tab at the top of the page. There is a sealant call out sheet for each model they build.

I would "Google" the sealants they recommend and find out what type they are. Compatible sealants can be found at local home improvement stores. They may not be the same brand, but will work fine as long as they are the same type. If any of them are Silicone be sure to clean off ALL the old sealant before applying new.

MoonDog,
Take a good look at the link & video below. It's from Lichtsinn RV which, is a company that is right down the street from Winnebago. They get all their guidance DIRECTLY from Winnebago. See what they recommend/say about what to use on that cove corner.

Scott,
That is a really good video and it likely saved me from wasting a lot of time by doing it wrong. I'm in the process of ordering the material. Looks like a bit of a chore but probably easier than coating a rubber roof. Can't thank you enough.
