Adventurer shower skylight leaks

[Yojimi]

Hello,
Can anyone give me guidance on sealing cracks on a shower skylight on an old Adventurer? What did you use? Appreciate your help.

Order up some Eternabond. You’re likely dealing with “straight” edges and that’s probably best for that. It’s likely that you currently have Dicor self leveling on there now. You’d nee to scrape that off.

I like the Dicor self leveling on horizontal like this. It will require removal of the old and I go with cleaning the area very well also. Depending on how old, I might also consider replacing the skylight at the same time. They do age and will eventually crack, so how proactive one gets is often a question. But much of the work of replacing will be getting the old sealer off, so there is something to be said for doing the whole now rather than waiting but there is no guarantee of how long the old one might last, either.
I find one of the multi-purpose tools with a scraper blade is really worthwhile. Getting the old off is a bummer, while putting the new caulk on is just pretty easy.

It's not clear to me from your post exactly what's cracked, the dome or the mounting flange? If the dome itself is cracked, Eternabond is a good temporary fix but replacement is the way to go. If the flanges need re-sealing, Eternabond is a good solution, both short-term and long-term.

Note that you don't need to buy an exact replacement (expensive). Any RV skylight that is big enough to cover the opening should work. With your inner skylight in place, you'll never know the difference. I wish I'd figured this out before I went the exact replacement route.

Take care of this asap. Mine was leaking long before I bought it and I had to replace a pretty large section of the bathroom ceiling's plywood along with replacing a few inches of the plywood under the fiberglass roof around the edges of the skylight. In order to replace the ceiling plywood, I had to remove the fabric headliner so I replaced it with FRP paneling from Lowes:

This is actually an improvement over the original fabric, which IMHO doesn't belong in a bathroom and shower.

It's not clear to me if it's the actual dome that's leaking or the mounting flange. If it's the dome that's cracked, Eternabond tape should work as a temporary fix but replacement will be necessary. A leaking skylight can cause extensive damage. My skylight dome had been repaired by the former owner but the repair had failed at some point and caused extensive damage to the bathroom ceiling and the roof plywood around the edges of the opening.

These domes are susceptible to cracking from low branches hitting them when driving under trees. I've been toying with the idea of installing some sort of protective grid, or possibly just a guard at the front edge to deflect any branches upward long enough for the skylight to get clear.

Exact replacements are expensive ($200+) but any RV skylight of similar proportions should work as long as it's large enough to cover the opening. Once your inner skylight is in place, you'll never know the difference. I wish I'd figured this out before ordering and installing an exact replacement.

Thanks for the heads up about Eternabond that should keep me dry until I can get a replacement.

The old sealant will be hard to get off. I thought that I may try using my Dremel tool and alcohol to cut the sealer. A new skylight is $200 + and shipping.

Thanks for the ideas on the repair and replacement.

I recently replaced the skylight on my 06 Sightseer. I ordered an aftermarket version, skylight sealant (butyl) and a tube of self leveling sealant. All for around $160.00 vs. the OEM version for around $600.00.


It was pretty easy to replace. Luckily the sealant comes off fairly easy because of the fiberglass roof. Make sure you clean the roof with mineral spirits where the butyl sealer goes. Also, don't use the four metal corner braces from the original skylight. You will need to buy some self drilling screws (stainless from Lowes). Finally apply self leveling sealant along the flange and the srew heads. Easy job!

We have a 2000 adventure and I replaced the skylight with an aftermarket - $179.00 plus taxes and shipping. For sealing all roof and gutter needs, I use a product called Through The Roof. Its a construction roof repair and sealer. Its $20.00 per quart and I sealed the new skylight, around all vents each end cap and both sides of the gutter. I also use it to reseal each year. I apply it with a small foam paint brush. Been doing this for two years and no problem
