One thing I have noticed in recent years during railfanning - where I like to be on a bridge above the tracks if possible - is that I am seeing cars which presumably had galvanized steel (unpainted) originally but after years of service, and perhaps some fork-lift driver "oops" events, the roofs have become dented and perhaps not even entirely watertight any more, and a gray sealant has been "painted" on the roofs (indeed I have even seen roofs where the "paint brushes" were set down and fastened into the sealant and are still there!) as part of the coopering process. That sealant is the same dull silver gray as duct tape. The color may be similar to unpainted galvanized steel but the texture is entirely different!
I have seen entire boxcar roofs coopered in this manner but I have also seen the sealant just applied to joints between the metal panel segments on the roof

There are also a lot of uninsulated boxcars with plug doors.
The builders of RBLs that I can think of are PCF, FGE, Evans, and CBQ.
Eel River Models and later Rail Shop also made a 12' door car. The side sills are different than the ExactRail car. The ERM/RS 12' door car is a model of SP class B-100-35. The ER car is a model of SP class B-100-49.

RBLs or in plain-speak, bunkerless refrigerator cars, are actually very heavily insulated boxcars. The roofs of these cars are usually a light color to reduce solar radiance heat gain which means white or light grey. The Eel River models mentioned are models of the Pacific Car and Foundry (PC&F or more recently PACCAR) and the major differences, just like the prototypes, are in the door widths, 10 or 12 feet. These cars were mainly employed hauling Coors beer from Golden, CO.
The Eel River model was offered as a "flat" kit which means the roof, floor, ends and sides are all seperate pieces which assemble to form the carbody. The later model by Exact Rail is a 12' door, ready-to-roll car. Excellent and informative articles for someone in the hobby less than 20 years appeared in the April 2000 issue of "Model Railroader" magazine and, the November/December 1981 issue of the now-defunct "Mainline Modeler" magazine.
The PC&F RBLs were operated by western roads such as ATSF (Santa Fe), BN (Burlington Northern), D&RGW (Rio Grande), MP (Missouri Pacific), SP (Southern Pacific), SSW Cotton Belt), and WP (Western Pacific). When empty, they always went back to Golden for another load of "Colorado Kool-Aid".
PC&F was not the only builder of RBLs. A hint what appears to be a regular boxcar might be a RBL is the presence of a plug door. If a plug door is present, check the AAR car code next to the "CAPY" or, "LD LMT" line in the car data to determine if it is an "X" type boxcar or an "R".

Somebody new to model railroading probably has no idea about the Eel River cars. For those new they are cars similar to the RBLs made by ExactRail but not the same cars. They were last made by Rail Shop models several years ago.
When I have seen RBLs that BNSF repainted it appeared they also painted the roof (no they did not appear to be rusted).
Rule 1: This is my railroad.
Rule 2: I make the rules.
Rule 3: Illuminating discussion of prototype history, equipment and operating practices is always welcome, but in the event of visitor-perceived anacronisms, detail descrepancies or operating errors, consult RULE 1!
Saffron Springs Are all modern boxcar roofs silver / galvanised steel?
Are all modern boxcar roofs silver / galvanised steel?
Yes.
Saffron SpringsShould i paint the roofs silver to be more prototypical or do some cars have the same color roof and sides?
It's quite common for roofs to be unpainted; some roofs might get painted/oversprayed, but they're still galvanized steel underneath.

Overmod Over the years I have seen references to roof coatings reducing heat gain or deterioration of 'membrane' on car roofs, though. I kept the reference I made accordingly -- but modelers should keep dhusman's point in mind.

That doesn't really sound like your references are talking about steel roofs...

I do not model the modern era, but I still paint my roofs lots of different colors and use all kinds of weathering patterns.
I see the roofs of my models all the time, and I want some variety to look at!

The idea of "silver roofs" is to not spend the money to buy paint to paint them. The roofs are made of plain galvanized metal because it doesn't need paint and since its the roof, nobody sees it.

One idea of silver roofs is to cut down thermal gain from solar radiation. Where that is not a factor (or unimportant to penny-pinching car ownership) expect something else to be used -- mastic to seal leaks? Paint with good rust coverage? Paint gotten cheaply, or 'on hand' from some other use? Good aluminum paint can be expensive...
I reccommend you use Google Earth to "fly" over a fair-sized railroad yard near you. Most recent construction boxcar roofs will appear a light grey color, similar to oxidized, unpainted galvanized steel, much like a chain-link fence. Older car roofs will appear an overall rust brown. Older roofs that have had repairs done will usually appear rust brown, with a grey sealant applied to the panel seams.
Some have the same color as the sides. If you don't have a place near you where you can safely railfan, check out youtube railcams

I model in N scale and micro trains boxcars generally have the same color body and roof. Should i paint the roofs silver to be more prototypical or do some cars have the same color roof and sides?
Thanks guys.
