White Roof Materials Are Cooler In the summer

Pale roofing materials are better than dark-coloured ones, according to a recent study. Findings published in Environmental Research, an online electronic journal, reveal that white roofing is more efficient in hot climates and is cooler than the use of black asphalt in the summertime.

The research, which took place in New York City, found that a light colour reduced the temperature of a roof and prolonged its life durability aspects. On the hottest day of the summer in 2011 in NYC, a white roof was 42 degrees Fahrenheit cooler than a black roof which reached 170 degrees Fahrenheit.

The results report that dark buildings absorb more energy from sunlight than light-covered landscapes which reflect more light. City roofs are traditionally black but the scientists' hope that tradespeople in the sector will opt for white membranes when replacing roofs in contrast to painted surfaces.

It is still not known how effectively the light is being reflected back into space, or whether or not it is being absorbed back into the atmosphere, but the study conclusion is that 'bright is the new black.'

One scientist at Columbia University, who was the lead author on the paper detailing the roof study, added that widespread installation of white roofs could cut down energy usage and therefore greenhouse gas emissions.
