Plants and Vegetation on a Green Roof

Roofing Solutions That Work

Most everyone today wants to do something they can to help the environment. Carpooling to work, reducing the amount of waste and plastic used, and conserving energy where we can. There is one area that many don’t realize can actually play a big role in the environment and that is your roof. A trend that has long been popular in Europe and is starting to become popular here is green roofing. This is a roofing system that utilizes plants and irrigation systems to provide quality roofing that is preservative, long-lasting and reliable.

Green Roof Construction

What actually is a green roof? Green roofing is a type of commercial and residential roofing where part or all of the structure is covered with vegetation. This is not the bad vegetation like mold or mildew, but carefully curated soil, grass, plants, trees, and more. Additional layers often include things like root barriers as well as drainage and irrigation systems. There are actually two types of green roofs: intensive and extensive.

  • Intensive Green Roofs: These are essentially elevated parks. They can sustain things like shrubs, trees, walkways and benches thanks to the complex structural support. There is usually often irrigation drainage and root protection layers as well.
  • Extensive Green Roofs: These systems are significantly lighter than an intensive roof, weighing only about 15-50 pounds per square foot. This roofing system sustains native ground cover that requires very little maintenance. Extensive green roofs are primarily designed for function and can rarely function as accessible rooftop gardens.

Growing in popularity, green roofs are a great way to invest in a long-term and highly beneficial roofing system.

Green Roof Benefits

Perhaps the number one reason anyone chooses green roofing is because of the increased energy efficiency. When exposed to light, plants absorb 50% of the heat while 30% is actually reflected back. In doing so, this helps to create a cooler space which means that your HVAC system won’t have to work double-time to cool the building. On top of that, there are several other great reasons to install a green roof.

  • Rainwater Drainage: One of the best advantages of a green roof is rainwater and irrigation. This roofing structure absorbs the rainwater which slows down water discharge into the sewer system. This helps to prevent overload which could lead to flooding.
  • Air Purification: Of course, plants convert carbon dioxide into oxygen. In polluted and congested urban areas, this roofing structure can provide incredible air purification benefits. 
  • Extends Roof Life-Span: A green roof will actually help to extend the overall life of your roof. That’s because the plants, walkways, etc. help to protect the actual roofing material from the elements, preventing aging, weathering, and damage.
  • Value: The natural beauty and the overall reduction in energy costs will significantly increase your property value. 
  • Reduces Ambient Noise: On top of everything else, green roofing acts as a sort of barrier or insulation to noise. In areas with a lot of outside ambient noise, this structure can help reduce that.

When it comes to green roof installations and repairs, you need to be sure that you are working with a reliable team of contractors. Just like you would only trust professionals for a fence installation, only rely on the professional contractors with Chisholm Trail Roofing & Construction for a green roof installation.

Green Roof vs Cool Roof

Is there a difference between green roofs and cool roofs? There actually is! As we’ve mentioned already, green roofing is a structure that involves plants, trees, shrubs, and more. The added benefit of the structure is longevity, energy efficiency, and an environmentally friendly system. Cool roofing, on the other hand, is often just a reflective layer of roofing, usually in the form an elastomeric or rubberized material. This structure also provides the added benefit of longevity, energy efficiency and often times environmentally supportive. However, the major differences are obviously the material and installation. A green roof is a system of plants, soil, and materials that are meant to create an environment for multiple purposes. A cool roof is just a layer of reflective rubber that can help cool your space but doesn’t provide much environmental assistance.

Frequently Asked Questions

  • What are the benefits of a green roof?
    • A major benefit is the improvement of stormwater management. Often in urban areas, there is little place for rainwater to go, so it pools and ponds. With a green roof, the water partly absorbed by the grass but is also properly shed from a roof.
  • How long will a green roof last?
    • Depending on what is installed and how well it is maintained, a green roof can last anywhere from 30 to 50 years. Green roofing can actually extend the life of a roof two to three times longer than its typical lifespan. 
  • How much does green roof cost?
    • According to EPA estimates, it could cost anywhere between $10 per square foot for simple extensive roofs and $25 per square foot for intensive roofs. Maintenance would be around 75 cents to $1.50 per square foot. 
  • Do green roofs really work?
    • Studies and surveys show that green roofing does in fact work. They are designed to help cool buildings while also adding oxygen to polluted areas. These roofing systems do in fact provide those benefits.
  • Why are green roofs eco-friendly?
    • They help to reduce the energy costs of buildings, which in turn helps to reduce the amount of energy needed to heat or cool a space. This means there is often less heat generated which can keep areas cool. Green roofs also add oxygen and plant life to areas that may be lacking those features.
