To help keep themselves cool, white colored or light-colored clothing are usually worn by people who live in tropical climates. Most people are aware of the fact that light-colored clothing reflects heat and sunlight; whereas dark-colored clothes absorb light and heat. Similar phenomenon is applicable when it comes to buildings, a building with dark-coloured roof will be hotter than one which has a light-colored roof. Roof paint if chosen as a light-color will save on yearly power bills by reducing summer air conditioning costs. Major purpose of any light-colored roof paint is to effectively reflect sun’s energy from the roof surface. Bright white color when used as roof paint, have high emissivity and thereby emit infrared energy. These types of roof paints are considered as cool materials. In comparison to ordinary roofs, painted roofs have reduced roof surface temperature by up to 100 degrees Fahrenheit. Roof paint prevents heat from entering in to the building below. This helps to reduce energy costs, cut maintenance costs, improve occupant comfort, greater roof life cycle and greatly contribute to the reduction of Global Warming. Moreover roof paint serves for another prime reason, extends the roof life by reducing expenses connected to maintenance and replacement. Roofs are possibly the most significant element of a house and habitually the most ignored one. Providing protection to the building and its occupants, roof and roof paint can certainly not be uncared for. As a result the awareness on roof paint and its positive effects on the building and its surrounding are very essential.
