Roof re-caulking

If you are physically able to get up on your roof you can remove the separated caulk and just re caulk, I can't see a 6 year old MH being that bad. Some times the caulk may crack somewhat just re caulk over the cracks. People have their favorite caulk but Dicor, Geocell and others out there all work fine. I have not used the Eternabond tape or other similar tapes but folks on here say they work good also. I would save the $1000 for gas.

If you can post some pictures we’d be able to give you a more accurate indication if you can apply Dicor right over the existing caulk or if you should remove. Either way, unless you are not physically able to do the job that is a lot of money to do the job.

I am a huge fan of eternabond

I'll try to send some pics. What's the best way to post images?

by separation, do you mean lifting off of the roof material. or splitting. unless original caulk is still sticking well, remove it.

More splitting. I'll try to post pictures, if I can figure out how to do that.

Yes, it probley does need to be re done after six years. By the time you experience a leak the damage is on the way. It's not rocket science if you are able to do it yourself. Choose the correct caulking.

If you can't do it yourself, contact a mobile RV Tech and get another opinion.

I acquired my 2006 Hurricane (also a Thor product) used in 2011 and pretty much all the roof seals had degraded and needed attention. Six hours of labor is about right but the labor rate at potentially $150 an hours is a bit high even for CA. You could certainly add additional sealant if you don't mind the "bigger the glob the better the job" look.

Removing old and resealing isn't difficult and there are Youtube videos which will help show a few tricks to make the job a bit easier. Lot easier then sealing a bathroom shower considering it doesn't have to look perfect just has to be weather tight. If you plan to attempt two words of caution NO RTV. Don't ask why not since this post is already getting long just NO.

I'm also a fan of Eternabond tape. The stuff is expensive at getting close to $1 a foot but once installed the tape will probably out last everything under it.

I have been just wiping clean with a damp rag and just going over the old caulk for 12 years now.

If existing is loose or pealing up then yes I would be removing at least the loose areas and caulk over.
