I’ve seen many articles over the past several months, and several in the last couple of weeks, including this article in the New York Times, all of which discuss the energy advantages to a white, as opposed to the traditional black, roof.
If your association is facing a re-roofing project, you should look into the potential advantages of white roofing over black. There may even be tax advantages in choosing to go with white.
Similarly, if your architectural/design guidelines deal with roofing colors, you might want to add white as an option. (Along with getting rid of the clothesline, solar panel and awning prohibitions.)
