Looking strictly at the economic costs and benefits of three different roof types -- black, white and "green" (or vegetated) -- researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span. While the high installation cost of green roofs sets them back in economic terms, their environmental and amenity benefits may at least partially mitigate their financial burden.
