Green Roofs

A green roof is a rooftop that is covered with living plants. Instead of just shingles or metal, the roof has soil and grass on top. Green roofs look beautiful and help the environment. They can be found on homes, schools, and tall city buildings.

What Grows Up There

Green roofs can have grass, flowers, herbs, and even small bushes. The plants sit on top of special layers that keep water out of the building. Some green roofs are like tiny parks where people can walk around. Others are just filled with plants that do not need much care. Bees and butterflies love to visit them.

Why They Are Good

Green roofs keep buildings cooler in summer and warmer in winter. They soak up rainwater so less water floods the streets. The plants also clean the air by taking in carbon dioxide. In busy cities, green roofs give birds and insects a safe home. They help make cities healthier places to live.
