Also, a layer of good insulation should be a lot more effective than this color-changing tile. Insulation will always work in the correct direction - keeps the house warm in winter, and keeps it cool in summer. ]]>Oct 9th 2009 12:23PMhttp://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/http://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/
But planting a big tree is hard (and expensive). You can plant a small tree and wait 30 years for it to grow big enough to shade the roof on your two-story house. In the meantime, I think these roofing tiles could help in some regions. In most of California, for instance, ice dams aren't a concern, so I'd rather have the roof be black in the winter there.]]>Oct 9th 2009 12:41PMhttp://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/http://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/
If it makes sense to use a white roof coating in the Summer, then it makes sense to use a black coating in the Winter (for those of us who have real Winters). I know two people who changed out their home's roof from dark to light. Sure, they saved SOME money during the sunny and hot season, but they spent more during the cold season. And yes, that's adjusted for the increase in cost per unit of energy. However, the extra cost for the white roofing will not be compensated for until well beyond the expected life of the material.

White roofs are only effective areas where there is a significant period of SUNNY weather. HOT weather won't make a difference to a white roof.

Also, why isn't everyone worried about the reflected heat causing atmospheric problems? It's been proven that reflected heat does cause problems. Think about the entire state of California blanketed with white roofs. What kind of meteorological impact will that have?]]>Oct 9th 2009 3:11PMhttp://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/http://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/Oct 9th 2009 3:37PMhttp://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/http://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/Oct 9th 2009 12:47PMhttp://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/http://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/Oct 9th 2009 1:00PMhttp://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/http://www.engadget.com/2009/10/09/roof-tiles-change-color-based-on-the-temperature-your-houses-m/
