Let’s talk roof maintenance.

Let’s talk roof maintenance.

The story goes like this:

I would notice white streaks on the side of my coach after the a/c had been running and the condensation was running down the sides. At first I was just annoyed and woud wipe it off and didn’t put to much thought to it.


Fast forward to my current Florida trip and the first time I was really caught I the rain while not driving the coach. I now notice white streak everywhere and have cleaned them off ( they pretty much wipe off) and having put some thought to it then realized what was happening was that this white chalky streaking is from my white roof.


The roof appears to be in perfect shape other than the chalky streaking.

So the question is roof maintenance.


Such as what types of cleaners to use ? And protectants ?

Should I just use tri sodium phosphate and a product like AmorAll after cleaning ?


I know I could go to Camping world and get the product they recommend; however I want to hear what the experienced folks here at iRV2 have to say first


Thanks in advance

There are many threads on this, my 2 cents

I would only wash my roof a couple of times a year and had the same problem.

Early last year I finally bit the bullet and really cleaned the roof using a mixture of Awesome In one bottle and tide and a little bleach in another bottle. I used a heavy bristle brush and got 90% of the dirt and mold off. I then took a small pressure washer and hit the stubborn spots, with some assistance from a stiffer hand brush.

Got the roof really really really clean, I mean whiter then new

I then, after much research and deliberation (there are many choices), decided to use Zep Commercial Floor Wax sold at many locations, I bought at Home Depot, I put on 2 coats. I used a small sponge roller on a long handle so it went on fast.

I was impressed with how we it looked and no more white streaks. About 6 months later I cleaned the roof again, not nearly as dirty, and applied another coat of Zep. The roof still looks good and since it is easier to clean and service it is easier to keep up.

I assume your roof is fiberglass?
I did the same as Jim did above last year, except I put 5 coats of Zep commercial floor wax on mine. Still shines and looks brand new a year later.
I also applied it to the skylight & vent covers, shine like new!

I recently had my roof coated with Nyalic. I expect many years of protection. it is easy to re-coat as well.

I suspect the a/c condensate tubes are plugged. You mentioned that a/c condensate was running down the side of your roof. That shouldn't happen. Regarding the roof itself the op have great ideas.

Painted mine with white marine epoxy...rolled on. Easy and eliminated the streaks/ The center (white) section of your roof is unpainted so you need to do one of the above choices to seal/protect it.


Some require reapplication, some more permanent, the choice is yours.

Funny that you mention the drain tubes for the evap cores.

They do drain, but I suspect that they don’t drain properly and are somewhat restricted because i do see water draining down the sides of the coach in many different places just from the a/c alone ( with no rain)

If this were a car? I would not hesitate to blow compressed air up the drain tubes to make sure they are FULLY open, clogging evap drains are pretty common in automotive a/c

I suspect that would not be a issue to blow compressed air back thru the condensation drain tubes , but would anyone with knowledge of the roof system care to elaborate as to whether this would damaged anything? I suspect not, but would like to check first

Wouldn't hurt a thing. Go for it.

On my coach the condensation drain had a splice/union up near the filter in the ceiling. I took this apart and used compressed air to clean mine out.

No drain tubes on mine. Anyone retrofit theirs. The water just runs off the roof.

Dicor for me. Self leveling and/or regular calking.

Clean your roof good and when it's dry, take Cheap sponge mop and put on 2 coats of Mop & Glo. It will take less than 10 minutes to put on a coat, and you will love it.
Nice and shiny and no more white stuff..

I do this spring & fall & love the results
