I would paint the roof white with a single stage automotive paint like an Argosy.
It will last 20 to 40+ yrs depending on how much exposure it gets and it wont cover up your rivet lines which I think are important to see.

Ceramiflex is a commercial roof coating, meant to go on metal roofs. Does not need extensive prep, just a clean dry roof. On mine the po had gunked up just about every rivet head with a nice dollup of silicone caulk, so I used a wire wheel to remove all that before I painted it. 2 coats would be a minimum, its fairly thin, but covers well and has small ceramic particles in it to help reflect heat and I would guess provide durability. It is elastomeric, meaning it will stretch with the expansion of the roof and not crack.

I've had it on for well over a year, no issues with streaking. It will darken a bit over time with dirt, but is still much brighter and cooler. You can recoat it as necessary, I did when I replaced the old AC unit last year.

It only comes in 5 gallon buckets. Did I mention it is a commercial product? It aint cheap, I think I paid about 200 for it. You have to get it from a roofing supplier, at least that is where mine came from. They had to order it. So far, absolutely no regrets with it. I'm sure other products will work too, just cant say whether they would work as well.

Automotive white, is a very good paint.

But, you need to sand, not scuff, but sand into the metal. Then spray a flexible primer on the metal. Let the primer age out for a day or two, and then apply 2 coats of the white.

That method will assure a absolute bond, and last about 40 years, or more.

I don't do the painting any more, but those that I have painted, using the above methods, are still around, and as good as day one.

I used a white Imron 3500 HG.

About a half gallon at about $105 a gallon.

Works great for helping to cool things down, covered with one coat, i doubt it will ever streak down the sides.

It can be brushed, rolled , or sprayed.

White Roof - Surface Coating

I researched this issue some, but not completely last week, and have some info and questions:
Ceramoflex is distributed by Sealoflex, and their primary distributor is in Charleston, SC. It is a water-based product, with" "nano"-sized spheres of ceramic, that aids in the heat reflection results. The SC technicians really know their product, but they are used to selling it to people with 5,000 SF roofs. Does anybody have a West Coast Distributor of this material?

Some of the distributors suggested a "solvent" based EPDM for the roof - elastomeric polymer dual? membrane, like an acrylic, not a polyurethane, that would be more compatible with the original AirStream white paint, that I do not want to have to sand off.

So, here are some of the other alternatives:

Imron 3500 HG

Dicor Elastomeric

Sealoflex Top Coat CT

Henry's Bright Whit Roof Elastomeric "Coating" which is not truly an Elastomeric

White Auto Paint with sanding and Primer

Any Others???
It would be nice to have a full technical basis of the proper choice at a cost of ~ an average of about $200/ 5 gallons.

We all want to do this only once, and do it right! Right!

Any elucidating comments???

Imo, the roof just being white is going to make the biggest difference.

A few weeks ago I bought a gallon of the Imron 3500 for less than $110.

You could paint the roof of an Airstream with a Half gallon no problem.

Whatever you use sand the roof well so it will adhere properly.

Wink Roof Coating - White

OK, and Thanks!!

A few ideas: At about $110/gallon, that's $550/ 5 gallons; and I am hearing that it takes 1(+) gallon per 100 SF for ONE coat, and you need at least 2 coats, which is about a minimum of 3 gallons for 2 coats on a 22 to 24 foot length Airstream. So that's a $300 coating cost (3 Gallons), plus materials (rollers, plastic shrouding, roof wash/prep, etc.). So this roof coating is a serious decision, right?

It is very interesting that the majority of the 1920s to 1930s travel trailers (see "Trailerama" by Phil Noyes - 49 Travel Trailer Distributors!!) had WHITE roofs, (down to the window ledges). There really is no doubt that a good Bright White roof will lower indoor temps about 15 (+) degrees from ambient.

The real decision factor is the additional roof protection that the coating offers, and longevity of the coating, over how much time, against the costs/labor effort, for which product is best. I'm still trying to figure that out!! I am 60, and I only want to do this once, like you all (y'all) while I am agile!!

Ideas/Input?? Any great technical info is welcome!!
JF

Is the Verdict In? Does Painting the Roof Cool Things?

No, It took about a quart to paint my 31 footers roof.

The half gallon I mentioned above was generous enough to allow for way more paint than is needed.

There is a half gallon on this truck counting the inside of the bed. The stuff covers like mad. Click image for larger version

This truck has one coat of paint.

With five gallons I could paint two of these and have paint left over.

As far as durability goes, I painted the red trailer about four years ago, it still looks every bit as good as the day I took this picture.

If you sand the surface well, this stuff will stick, and I promise you it WILL last.

If you look real close at this picture you can just make out the area that I painted my roof.

I had to compromise between shiny aluminum and painted area. If I had to do it over again I would paint further down the sides, not to the windows, but somewhere in between there.

When I lay one hand on the white and the other on the aluminum, I can tell a big difference in direct sunlight.

Paint, applied to sanded aluminum, will not stay in place very long.

Sanding, very well, of course is a must, but then a good flexible primer must be used to assure longevity for the white paint.

Time, has more than proven that fact.

I have 25 years experience that says sanding alone well does the job just fine.

IMHO the reason self etching primer is seen as essential is that OEMs prefer not to sand, and use the etch as a labor saver.

The biggest enemy of paint over aluminum is too thick of a film, this magnifies the problems of aluminum expansion and contraction.

The etch primer wont hurt anything, and in fact may help some with adhesion, but imo it is not needed so long as the aluminum is well sanded.
If used, it should be used in very very thin coats.

Acids or self etching primers should NEVER be used on an Airstream.

The small amount of acid can and does get under the rivet heads, and in time, will eat through the paint and then you have a nice horrible water leak.

History has shouted that out for many decades.
