They keep your house cool in the summer and warm in the winter. In the summer, it’s like living underneath a cave. Plants and greenery help absorb the sun’s rays. In the winter, the green roof provides insulation and breaks up the cool air.
2) Green roofs prevent floods
Green roofs hold on to water. Preventing it from reaching the city below all at once.
