According to the recent news, climate change is very evident today. We are called to lessen our carbon footprints and move to a more energy-efficient lifestyle. If you’re building your new home and want to take part in the movement, you can consider using a green roof in your new home.
Green Roofing is a vegetative layer that is put atop the roof. Green Roof is both eco-friendly and practical as you take a lot of benefits with it. They are self-sustaining so they to adapt the local environment. Green Roofs have different types: extensive and intensive.
Extensive Green Roofs are a simpler type whose growing medium depth is less than 6 inches and can grow a limited choice of plants. These are lightweight which means it doesn’t require much structural roof framing support.
Intensive Green Roofs are a more complex type of which its growing medium depth is deep enough that it can support small trees, due to its deep soil, it can grow a wide range of plants and habitats. They require more structural framing support to carry the greater weight.
Components of a Green Roofing System:
-Structural Roof Support
-Vapor Control (Waterproofing system)
Benefits of Green Roof:
1. Energy Efficient
The vegetation creates a stronger boundary that lessens the absorption of heat by a significant percentage and it also creates more insulation in your home. This reduction in heat absorption will cost you less in your cooling system during the hot sunny days and locks in the natural heat temperature inside on the cold days. The plants also benefit from this process as they also need the right amount of heat and water to grow.

2. Noise Cancellation
It creates more sound barriers than those usual materials. It absorbs sound, providing a quieter and calmer indoors.
3. Better Water Drainage
Because of the increasing urbanized housing, it also calls for an increase in drainage to be able to accommodate the rainwater to avoid flooding in the area. Green Roofing addresses these issues as plants and substrate accumulate rainwater during the heavy rains and filter it during the process before it releases into the environment, this lessens the amount of stormwater in the local drainage system.

4. Longer roof lifespan
Roofs are the initial barrier of our home against natural elements from getting in our home, but as plants are part of our environment it also benefits from it. The possibility of it being damaged due to rain, wind, or animals is little to none which means that cost for repair and maintenance is lesser over time.
As our community releases more carbon dioxide, it contributes to global warming. Green roofs being present in highly urbanized communities helps filter carbon dioxide and release oxygen into the environment. With plants present, it will also act as a home for birds and other animals.

What is the common challenge it faces?
The most common challenge that green roof faces in Texas is the variety of plants that can work well with the intense weather condition. A study shows that the most native plants in Texas need deeper soil beds in order to adapt to and withstand the harsh environment. You can still push through with your green roof projects as there are advisable plants, shrubs, and flowers that can work well on the roof though limited. As the world evolves, so does the intensive search and methodology to allow more native plants to live on the roof of Texas homes.
