Introduction: There are many types of roofs. There are slate roofs and cement roofs. For our exit project in 8th grade we are seeing if a living roof is more efficient than a regular roof. A living roof is a roof that has plants such as wild flowers and or moss. These roofs absorb harmful chemicals such as carbon monoxide and purifies them and the surrounding air. In the summer it absorbs up to 5% of the heat that really keeps you cool. In the winter it insulates you from the cold very well. It lasts twice as long and when it brakes it does not cost nearly as much.
