Went up on the roof this past weekend, when i first picked up the Rig i noticed some pretty sloppy looking GOOOP spread all over the seam areas of the roof. The roof is fiberglass and in general pretty neat and sound in appearance but this weekend after seeing those seams again, i cant help thinking that there must be some other way to address them. Are all these fiberglass roofs looking the same? how about that Eternabond tape? Nothing is leaking, it just looks like someone went up there with a spatula and cake frosting, thanks Gene....

One more thing to add, my Rig is sitting level but because of the caulk mess, drainage is not able to happen on one corner,so i hold water. I am not sure but if think if i lower the cake batter (caulk) the roof may drain better, Gene

If your roof doesn't leak now...you are in luck. Remember that the sealant around things does tend to dry out and check/crack...probably should be re-coated at some point.

couldn't you take goop off and just fiberglass seams? or does goop expand to keep from cracking? are rubber roofs any better?

What i am looking to find out is how everyone else with a fiberglass roof has the seams treated. My Rig is made by Silver Crown. Renegade, Haulmark, Showhauler, and all the rest, do they use fiberglass roofs, and if so, how are the seams treated? Gene.

I have a translucent fiberglass roof that came on the truck. I sealed the joints with a butylene caulk and then painted the roof with liquid rubber. I was told to use something that can handle the expansion and contraction, thus use
materials that stay flexible after curing.

Our roof is one large sheet of aluminum laminated over plywood and folded over the edges. The edges have a corder molding cap that is sealed with the butylene caulking. This type of caulking is pretty tough stuff and made for these types of applications. With out a tramatic event like an accident or a tree strike it will last a good long time. My last RV was over 15 years old before I had to attend to the roof caulking. It was stored outside in direct sun light and the touch up was minimal. I bet todays materials are even better...

GENECARP, The Renegade roof is FRP and it is connected to the sidewalls with a heavy extrusion. The roof is caulked with "Silaprene" caulk, both during construction and after on the edge of the extrusion. Very good stuff!!
