Critics have suggested white roofs do.

How do white roofs reduce smog.

It has long been known that installing white roofs helps reduce heat buildup in cities. But new research indicates that making surfaces more light reflecting can have a significant impact on lowering extreme temperatures not just in cities but in rural areas as well. The first is reduced air conditioning costs which can drop 15 to 20 percent. Known simply as cool roofing this process is designed to reduce the solar radiation.

A white roof project is low cost easy to implement relieves stress on the power grid cuts down on smog and creates tangible change for individuals our communities and even globally reports the group which is looking to expand its work across the country significantly in 2013 and expand internationally in 2014. A lighter colored roof will reflect as much as 80 percent of the solar radiation that hits your house back into space. This roof type may not be as eco friendly as meets the eye. In metropolitan areas white roofs also help reduce smog levels by lowering city temperatures.

In 2017 more than 3 000 city rooftops were painted using both white lime and a special reflective coating. Black roofing is also responsible for heating our waterways. Don t jump on the white roof bandwagon just yet however. The second benefit is more cosmic.

In urban areas white roofs also help lower smog levels by lowering local temperatures which tend to be higher due to the large proportion of paved surfaces. The latter tends to be higher in urban areas due to the mass heat absorption from paved roads.
