So, here is an update on this project.
I went ahead and had the RV Armor applied and they finished up my project this week. I had new sewer vents put on as well as a new skylight. The other vents were okay.
This was my roof before RV Armor and after Debby and I had cleaned the RV up. It was in bad need of refurbishment.
This is after. The old sealant that was cracking was removed. The old Eternabond type tape was removed. New sealant was put down and then the whole roof was coated with their rubberized coating. Now, no seams up top to leak. They also bring the coating down into the gutter, so the gutter is also covered under the lifetime warranty.
I was worried that I was going to have to have some of my roofing replaced because of the leak I had in one of the front corners. We must have gotten the leak sealed up fairly quick because the roof was still nice and solid. The process itself wasn't all that difficult since I didn't have to have the roof replaced. There may be other products out there that will do essentially the same thing as RV Armor, if folk are interested in doing something similar to their RVs. Basically it was washing the top, removing the old eternabond tape (not compatible with the RV Armor stuff), removing old sealant, putting on new sealant, priming the top, waiting for that to cure (over night) and then putting on the rubberized coating. Time consuming but not difficult. But I am very happy with it.
Now to chase down my electrical gremlin.
