When the PRR was using plain-steel sheet for their lap-seamed roofs, they seemed to have less paint flaking problems than when they went to galvanized roofing (immediate post-war).
Do you mean the PRR did not used galvanized roofing until World War II?? It is evident from Railway Age that many roads were using galvanized steel back in the days of inside and outside metal roofing. That dates back to around 1905.
