Apart from their attractive appearance, green roofs offer numerous clear ecological and economical benefits, provided, of course, that the correct system build-up is employed to ensure long-term success. Green roofs are worth it, from installations on small garage roofs, right up to installations on large industrial surfaces. Ecological benefits Economical benefits

Temperatures on the roof surface have an effect on the indoor building temperature; in turn, this contributes to the amount of energy required to heat or cool the building. The additional vegetation layer over the roof acts as a buffer between indoor and outdoor temperatures. As well, during summer months plants will transform heat and soil moisture into humidity which in turn cools the surrounding environment, including the building. During cooler months, the buffering capacity of the green roof provides insulation against heat loss through the building roof. Accredited thermally insulating drainage layers add to the insulating capacity of the green roof and therefore, help maximize insulation benefits. By reducing temperature fluctuations within the building, less energy and less cost is required for temperature regulation.

It has been proven that green roofs can insulate up to 3 dB for internal sound insulation, and up to 8 dB for reflective sound. The layers of the green roof build-up, such as, substrate, plants, and trapped air, help to provide insulation of sound waves. Expressed in figures this might not be very impressive, but a noise reduction of 10 dB appears to the human ear as a noise reduction of 50 %. This can be especially advantageous for buildings near airports, or perennial machine activity as well as for noisy discotheques. In addition, high frequency electromagnetic radiation from mobile stations can also be effectively shielded.
