light colored roofing

Urban heat island profile

white colored roof s 20 degrees celsius cooler than dark colored roof. see experiment below using an infrared camera.

spot 1 (white color) = 42.9 deg c

spot 3 (black color) = 64.8 deg c

painting ur roof w/ a high albedo (light colored & reflective) coating can help lower the air-conditioning expenses since dark colored roof absorbs the sun’s heat. in tropical countries like the phils., dark colored roofs should be avoided since we don’t want to heat our house coz we don’t have winter snow anyway.

dark colored roofs also contribute to ‘urban heat island effect’…..

so paint ur roof white for a cooler world…..
