Dec 14, 2010-Department of Energy implements cool roof technology and directs all DOE offices to do the same.
Americans spend $40 billion to cool buildings. This is one-sixth of all the energy consumed in the U.S. The Environmental Protection Agency says that over 90 percent of the roofs in the United States are dark colored. Dark roofs absorb heat, make buildings hotter than necessary and lead to higher energy use and CO2 emissions. This is very uncool.
The alternative to a dark hot roof is a light cool roof because the white color of cool roof coatings reflect 90% of solar thermal energy and,therefore, absorb less heat.

In fact, scientists at the Lawrence Berkeley National Laboratory in Berkeley, California estimate that permanently retrofitting urban roofs and pavements in the tropical and temperate regions of the world with solar-reflective materials would offset 44 billion tonnes of emitted CO2, worth $1.1 trillion at $25/tonne.
Cool roof coatings, depending on the type of coating selected, will extend the life of your roof 10 or 20 years and carry warranties against leaking.They are applicable to almost any kind of roofing material – bitumen, tile, cement, tar, shingle included.
With cost at just a few dollars a square foot, these coatings are a smart alternative to re-roofing that will SAVE you money. Cool roof coatings make Sense and Cents!
