2016 Thor Vegas Roof Sealant?

[Muggs]

I just came off roof of 2016 Thor Vegas. The original Gray sealant is looking weathered. I think I need to re-seal all the joints.

Has anyone done this? What material was used? Not sure of original supplier of the Gray self leveling stuff.

Thanks in advance.

I believe they make it in gray too.

Use self leveling lap sealant especially for RV roofs as Oneilkeys says. There are several brands. Use this stuff on the roof only and remove the old sealant if it’s badly deteriorated or clean it very thoroughly with mineral spirits before applying new. For sidewall penetrations like windows and light fixtures use polyurethane caulk. It’s harder to find than silicone but works better. It’s quite sticky and not as easy to work as silicone so I sometimes cheat and use the latter on windows and lights. I do however only use the polyurethane for big side seams like front and rear caps or corner edging. Check everything at least 3 or 4 times a year. I need to see that the caulk entirely fills every gap. They really don’t tell you about the need to do this when you purchase but sealing is VERY tentative on these things!

I agree with PeteMH, All of the roof seams need to be the flexable Dicor "self leveling sealent" and anything on the walls (vertacle surface) you can use NON-leveling Dicor (were the walls meet the roof) and I use clear silcone around my windows or any other holes/vents.

I use a tube of that every other year on our Axis. Just go up there and add to areas that look like they need it. I usually use white--it ends up looking grey by the end of the season anyway.

This year I used a tube when replacing the front vent with a fantastic fan..

Yeah Dicor is your friend. Dont wait until you have a problems. Most things on an RV you have to be pro-active to insure less problem and headaches in the long run.

Plus its pretty tastey on crackers.

We do not have any evidence of leaks yet. I ordered the white, also putting covers over vents and is time for spring cleaning. I tend to be proactive with all the horror stories plus I am retired now so taking a little extra time is no issue.

I still hate washing roof. Cannot wait until Grandsons grow a little more.

Yep, the first time I was on the roof was to wash it.... I was a little nervous standing up and walking around. Plus I didnt want to cause any damage (didnt know how strong it would be walking on it).

But since then I been on the roof 10+ time for other things (add stuff, checking on stuff or modifying AC unit etc). So its not such a big deal to me now.

But it would be nice to have a little apprentice. LOL.

I know I’m a broken record on this but you can’t be too proactive on leak prevention! I’m on my roof every couple of months on my hands and knees examining EVERYTHING. I address even the tiniest cracks. On every roof and side seam, if I can’t see an unbroken bed of sealant I’ll fix it until I can. I’ve had water damage and it’s not pretty!
