The basic properties of light and heat haven’t changed. People still wear white clothing to stay cooler in hot climates because white reflects the sun’s energy, while black absorbs it.
So why continue to pay the price in higher energy and maintenance costs for that black roof on your building?
If you’re thinking about a commercial cool roof, you need to understand the basics. Like how much of the sun’s energy a white roof reflects, and how long the reflectivity lasts.
Urban Heat Island: Truth and Consequences
You’ve probably heard about the “heat island” effect: the tendency of urban areas to reach temperatures from 3 to 8 degrees Fahrenheit above the surrounding countryside.
But do you know what heat island means for your building’s energy and maintenance costs and what you can do about it?
- Nearly half of the U.S. population lives and works in ” heat islands.”
- 38% of the heat island effect is attributable to dark roofing, which absorbs more sunlight.
- More discomfort, resulting in lost productivity.
- Increased energy cost as air conditioners work harder to keep building cool.
- Higher maintenance expenses due to accelerated aging of building structures.
Cool Roof Solutions for Hot Buildings in Phoenix
White roofing is one of the fastest, easiest, least expensive, and most effective ways to reduce energy consumption in buildings with low-slope and flat roofs. Mostly cool roofs are associated with white roofs because light colors can typically reflect more heat than dark colors. White roofing can be applied to both commercial and residential buildings. For existing roofing, we can also add a solar reflective coating to save energy and reduce heat. If you want to get more information about white roofing services in Arizona, please contact us today!
