The most obvious benefit of installing a cool roof is your energy savings. Since cool roofs do not absorb as much heat from the sun, your home will be colder. This means you will not have to use your air conditioning as much during summer months. Who doesn't want to save money? If you're using less electricity, you're contributing less to the peak demand for it. This can help reduce power outages as well as avoid those peak demand rates. Lower energy rates means you'd be paying even less with a cool roof because you're consuming less at a lower rate. What's not to like about that?

If you and your neighbors installed cool roofs, you could reduce your local air temperature. Have you heard of the urban heat island effect? An "urban heat island" is a densely populated area that is lacking natural moisture as a result of infrastructure in the place of vegetation and open spaces. This lack of moisture causes a surface, such as a roof, to increase its temperature to 50-90 degrees Fahrenheit hotter than the actual air. Cool roofs can significantly reduce this effect, especially in mass quantities, by putting off less heat than darker, traditional roofs.

Decreasing your roof's temperature can also extend its life. When a dark roof absorbs heat, it stresses the construction and as a result, shortens its lifespan. Of course, a lot of a roof's life expectancy is related to the materials it's built with. However, regardless of the material, if a roof is absorbing less heat, it won't deteriorate as quickly.



BENEFITS

  • Save on annual electricity bills by reducing summer air conditioning costs.
  • Save peak electricity demand costs if you have time-of-use metering.
  • Reduce roof maintenance and replacement expenses by extending roof life.
  • Increase indoor comfort in summer by reduction of infrared conversion from visible light.
  • Reduce the “heat island effect” in cities and suburbs.
  • Reduce air pollution and smog formation.
  • Reduce roofing waste added to landfills.
