I understand saving money. But what is an ‘Urban Heat Island?’
Have you ever noticed that it’s hotter in cities and larger towns than it is in rural areas? Especially in the evenings? There’s a reason for this. An ‘Urban Heat Island,’ is the term for urban or metropolitan areas that are significantly warmer than their surrounding rural areas due to human activity and building practices. This is in large part due to traditional roofing materials that hold heat in and towards the buildings. Remember science class? Dark colors absorb heat and light reflects it away.
Historically, few home builders or homeowners opted for energy-efficient cool roofs because it used to require the roof to be white. But that’s not the case anymore. Thanks to military research and technology, there are now roofing materials that are darker in color (what homeowners typically prefer), but that also reflect the majority of the sun’s radiation and heat. Heating bills may not change much, but the reduction in cooling costs, especially in climates with hot summers, makes up the difference. These new roofing materials come Energy Star® Rated.
