In accordance with the cases that used the technique, it was found that extensive green roofs are more used due to the lower cost and ease of maintenance, it is also concluded that green roofs are efficient for the reduction of heat islands, due to the reduction of CO2 in the atmosphere by evapotranspiration, increase in air humidity, are also advantageous in terms of thermal comfort and acting as an aid to reduce electrical energy. In addition to a great measure for improving urban drainage with the expansion of permeable areas and avoiding: flooding, flash floods, water erosion and flooding. It is concluded that green roofs have a great positive impact, cooperating for sustainability, reducing the impacts caused by civil construction and generating greater comfort and economy for users.
