In fact, using a cool roof that efficiently reflects visible and infrared light from the sun-and also radiate heat at night-is one of the most important energy cost-savings strategies in locations with hot climates, such as Las Vegas.
In lowering the surface temperature by reflecting heat from the sun, a durable and highly reflective bright-white coating helps ensure a long roof service life with minimal maintenance, decreases air-conditioning load and reduces energy consumption by as much as 18 to 26 percent.
Not only does this heat transfer to the interior of the building, but it also accelerates the deterioration of the roofing materials. Most conventional roofing materials absorb solar radiation, causing a rise in surface temperature.
