This is good in areas like cities where they can be affected by blackouts and brownouts due to too many buildings retaining heat. This is dangerous when there is a heatwave, as air quality goes down.
Cool roofs lower electrical demand, which is a very good thing at peak heat times of the day. This is when electrical systems can become overloaded with air cooling devices such as air conditioners.
In some cases, a installing a Cool Roof could result in utility rebates. Saving money is never a bad thing.
