This is not as simple as just tossing some grass seed on the roof of your home, of course, but the basic principle is the same. Offsetting The Urban Heat Island Effect Green roofing systems, such as the M-TRAY® green roofing system, can also help to offset the urban heat island effect. Because cities are full of roads, roofs, and parking lots, they tend to absorb a lot of sunlight, making them several degrees warmer than the surrounding country. By putting a green roof in place, you can help to offset this effect and start to cool your city back down again to a more reasonable temperature. Green roofs can absorb both dust and pollutant gases and also offer water attenuation qualities (up to 50% at 100mm depth). They also cool buildings rather than having the hard surfaces radiate heat out at night. There is also evid
