BarneyS & Goostoff,
Thank you both for the good words. Very much appreciated.
And Goostoff, you are very welcome. Wow, I'm humbled by your response.
If you need any help or pointers on roof repair or replacement of a bad area, just ask. And the coatings, I have a "lot" on the Henry's and the Crazy Seal to share if wanted if you decide to go that way. These coatings once applied, correctly, can last the life of the camper for your use and they deal with the failing caulk issues. They also $$$ more. But, before going this route, ask and understand all that is needed to make it come out that way.
I have seen the Dicor 2 part acrylic coating and it is OK, especially if you go over new good sound caulking. The coating deals with restoring the wearing shed layer of the EPDM. However, the joints where the caulk is, is where some of the thinner coatings can have issues. Long term flexing in the caulk areas can raise havoc on some coatings, by your going new caulk really helps under the this type of coating. Also make sure you do not have any ponding water areas on the roof as they can break down acrylic coatings over time. The cost is a lot less, but the life of the product is not as long. This all comes down to, how long do you want the roof to last, can you get up there and deal with it on the shorter life, and the cost benefit.
Anything to do with a camper roof has + & -'s. Even by going with a new roof replacement done the same way the OEM's did them, have the caulking joints as the failure mode early in the life cycle, along with high annual maintenance. And even then, the thin membrane only lasts so long before it needs to be coated or replaced. The coatings systems help, some better then others. The RV industry did not make campers to last as long as some of us like to use them.
I have lots of pictures etc. and details to share for a fellow camper bud to help, if needed.
Hope you roof project comes out well.
John
