The waterproofing of the soil coming from the urbanization interferes directly in the hydrological cycle, since the scenario previously covered by the vegetation gives space to the waterproofed scenery of the asphalt and the concrete. This causes a reduction in the infiltration of precipitated water, leading to increased runoff and flooding. The objective of this work was to compare experimentally the hydrological performance and costs of green roof of polyethylene terephthalate - PET (TV I) with commercial green roof (TV II) using asbestos cement roof as standard. The performance of TV I was slightly higher than the performance of TV II for the delay of the runoff. In addition to this, the cost of the roof constructed with PET is less than the cost of the commercial green roof, disregarding the costs of manufacturingand assembling the green roofs. In this context, it can be stated that the green roof can contribute significantly to the reduction of floods and that the use of recyclable materials in the construction of green roofs proves to be a viable alternative both environmentally and economically
