GREEN ROOFING: EVERYTHING YOU NEED TO KNOW

What is GREEN ROOFING?

A green roof is an addition to an existing roof that allows for the growth of flora. The type of green roof that you choose will determine whether the plants are modular or have drainage layers. To ensure that the structure is safe and unaffected, green roofs must include some important features such as root repellent and waterproofing.

DIFFERENT TYPES GREEN ROOFING

There are two main types of green roofing: extensive and intensive. The amount of vegetation used determines which type you choose. Green roofs with extensive green can support up 25 pounds of vegetation per square feet, while intensive green roofs can accommodate 150 pounds.

The amount of work required to maintain each style is another factor that distinguishes them from each other. As the name implies, intensive green roofs require more effort to maintain as it involves keeping different types of plants separated and maintaining a garden. However, extensive green roofs can be left to grow naturally without any restrictions, taking care of their plants as they would in nature. They only require yearly fertilization and weeding.

Private homeowners can choose the flowers they would like to see in the intensive format. This allows them to create the look that they desire. Because extensive green roofs are meant to be accessed only for their annual maintenance, they naturally become overgrown. It is therefore more difficult to navigate extensive green roofs, so people can’t enjoy the area’s flora.

Layering is used in both green roofs. This creates a foundation for planters by using various soils, mats and other materials to retain nutrients and force out waste products. These layers create a soil profile that is replicated, which allows liquid to flow through the system safely and also provides nutrients for the plants.

Comprehensive roofing is a new type of green roofing that has been developed through recent research and advances. This type of roofing is designed to support many different plants. It is also more flexible than intensive roofing.

BENEFITS OF GREEN ROOFING

There are many reasons that a person might want a green roof, including the improvement of their home and community.

COMMUNITY BENEFITS INVOLVEMENT:

  • A green roof can reduce stormwater runoff and the strain on local sewer systems.
  • Green roofs are a great way to reduce heat loss in urban areas by covering the most radiant surfaces.
  • These plants not only prevent the spread of smog, dust, but also capture many pollutants in the air.
  • The community can enjoy green roofs as public spaces such as gardens and recreational areas.
  • Because of the work and money involved in the installation of green roofs in a community, it can lead to an increase in jobs and revenue for local business.

HOMEOWNERS CAN ALSO RECEIVE PERSONAL BENEFITS, WHETHER THEY ARE LOCATED IN URBAN or RURAL SETTINGS.

  • Green roofs reduce noise by creating a natural barrier.
  • Your roof is protected by plants so it is less exposed to the elements. This allows the roof membrane to last longer than if left unprotected.
  • Green roofs can reduce your heating costs by reducing the energy required. This will save you money.
  • Green roofs help protect your home from fire.
  • Green roofs are a way to reduce the waste produced by your home. They use waste products that would otherwise go into landfills and also extend the life of other household products such as an HVAC system.
  • You can increase the value of your house by adding a green roof. Your home will also be more attractive due to its increased efficiency.

NEGATIVES OF GREEN ROOFING

Green roofing is an option that will benefit your community and you, but it can also be costly. This can result in unexpected expenses.

  • Green roof insurance is essential due to the possibility of droughts and unforeseen storms. However, it is also expensive.
  • If the roof is too heavy, it could lead to liability issues.
  • Repairs will be required for any damage caused by the plants, such as roots getting into the roofing shingles.

DEVELOPMENT OF GREEN ROOFS

Long ago, the first green roof was invented. The Hanging Gardens of Babylon in Babylon, 500 B.C., is the oldest known example. The structure was constructed on stonework using tar and reeds for the lower protective layers.

The modern method for building green roofs was developed in Germany in the 1960s. This led to the layering system we use today. Although this practice is quite common in Europe, it is just now that it is becoming more popular in the United States.

Because technology has advanced, modern green roofs are also different from ancient ones. Today’s green roofs are made from soils, three types of fabrics, drainage plates, mats, and three other layers. These drainage systems are also different from the previous versions because they use the soil’s natural tendencies to direct the water in ways that make it easier to maintain.

Engineers and scientists are still trying to find the best green roofing methods. This research focuses on the different ways that green roofs can be constructed in different environments and climates, as well as the size at which they can be made.

THE COST OF GREEN ROOFS

Green roofs cost between $15-$25 per square foot for intensive roofs and $10-20 for extended roofs. The soil and concentrates used to grow the plants are a large part of the cost. The cost of individual plants will vary depending on whether they are to be planted or pre-grown using a vegetation mat. It may also impact the availability and ease of getting the materials you need. Although none of these parts are difficult to find, it may be costly to transport them to your home.

Contrast this with the current cost of a green roofing in Germany, which is between $8 and $15 per square feet. This is due to both the innovation in the U.S. industry and technology and the rise in custom projects that are associated with this market.

It is important to consider long-term maintenance when determining a budget. This may not be necessary if you have a large green roof. However, it can still be costly depending on how big your project is. This is usually a free service that is included with certain companies’ services. However, the average cost per square foot is between $0.75 to $1.50.
