I don't know if you've ever re-roofed your house, but choice in roof color is influenced greatly by where you live - light colors often chosen in southern areas to reflect the heat and keep the attic cooler (thus the house), dark in the north (helps heat the house in winter, etc)
Most city roofs have flat, black, asphalted roofs. Trouble is, there's not a good substitute for black roofing asphalt. So another "thing" becoming very popular is roof gardens - even things like planting a whole acre of roof in short wildflowers. Stops the heat reflectivity of the black roofs. Keeps the building insulated all seasons. Helps with rain runoff/flooding locally, too
