Recently, the secretary of energy has come out with a statement saying that $40 billion dollars is spent annually to cool buildings in the United States. Dr. Chu said this large amount of money can be dramatically decreased if Americans just paint their roofs white!
The idea is that white does not absorb as much heat as a non-reflective darker color. The result from a mass change of roofing color across America will reduce global warming, reflect sunlight back into space, and the most immediate and most practical to homeowners- save on energy bills!
If you think a white roof is tacky, another great option that is arguably better than painting your roof, is to replace it with a highly reflective metal roof. This will reduce monthly bill dramatically.
Taxpayers! please note: “Between January 1, 2009 and December 21, 2010, may be eligible for a tax credit worth 30 percent of the installation costs (materials only) up to $1,500 per home.”
