Why silver and not white?
- crazygringo 3y agoGood question. I can't easily find an answer, but this page at least seems to describes the type of silver roof common on old NYC buildings: https://flatroofdoc.com/silver-coating-protecting-a-rubber-roof/amp/ https://flatroofdoc.com/silver-coating-protecting-a-rubber-r... Elsewhere I find a claim that the aluminum paint used was a 20th century thing, but now white paint is preferred as being more reflective.
