Roof Coating - 96 Dynasty
Input is needed. How do you coat your roof? Or, DO YOU coat it at all? I have a few leaks coming in from various spots ... roof vents, lights, shower, down the walls. Not a lot and sometimes none at all. I read that the Dynasty fiberglass roof does not need coated, just around the AC, vents, skylight, and other stuff sticking out. (We will not talk about the front windows coming out and leaking around them at this time.)
Thanks for your time this time, till next time.

Here is a link to the prep, sealing and coating of my then 16 year old fiberglass roof: RVing: The USA is our BIG Backyard: Coating Mel and Paula's RV Roof with Elastomeric Paint

I inspect my roof several times a year and as needed I will repair and cracks in/around the caulk on vents and other openings. I had one leak develop around the fantastic fan, the caulk was cracking so I resealed.
I cleaned the roof last year really good and then put a couple coats of Zep High Traffic Commercial Wax on to prevent the roof from oxidizing. It seems to be holding up really well +10 months into do it.

Mike,
First thing. You have to stop all of the leaks. Not sometime. NOW. Reason: the fiberglass sheeting on your walls is glued to very thin Luan plywood. If water touches that glue, it's delamination time. It's a really poor design.
The roof. Everything that's on that roof is caulked. It's time to remove all the old caulking. If you don't have the time and/or the energy to remove the old caulking, then at least apply a new layer of self leveling caulking to avoid any leaks. Dicor makes a good self leveling caulking for roof work. The self leveling caulking needs to be inspected annually and patched or replaced as needed. Another really good option is to use Eternabond tape. Eternabond tape is basically permanent.
The roof. Once everything is caulked, check the fiberglass for cracking. Eternabond tape is great for crack repairs. Heng's acrylic coating is also great for roof crack repairs. If there's quite a bit of fracturing and cracking from age, then it might be time to consider painting the roof with one of many available roof coatings.
The sidewalls. There's a seam trim joining the roof to the sidewall near the top of the sidewalls. You cannot let that leak at all! Any leakage there will ultimately cause the sidewalls to be destroyed with delamination. Geocell 2300 or Geocell Pro RV are two good choices for caulking this seam. Silkens makes good caulking for this also. All of these should be available at Camping World or most RV dealerships. This seam needs to be inspected annually and caulking repaired/replaced as needed.
Your windows. A quick caulking job along the top of each window with Geocell should solve it for now. If you have to, you can remove each window and replace the factory putty caulking.
Another greatly overlooked cause of water leakage are the front clearance lights above the windshield and the rear clearance lights at the top of the rear cap. The simplest best way to assure these clearance lights are not leaking is to caulk them with clear silicone. I don't like using silicone, because it jeopardizes any future repainting efforts. But silcone is the easiest to remove to get the lenses opened up to service the light bulbs if/when they burn out. And, let me assure you, they do burn out.
Jim
