Green roofing is divided into three categories based on the depth of the planting and the level of upkeep required: intensive, semi-intensive, and extensive. Extensive roofs can support 10 to 25 pounds of plant per square foot, intensive roofs 80 to 150 pounds, and semi-intensive roofs anywhere in between. An intense green roof is more like a rooftop garden, requiring a lot of work, irrigation, and feeding to keep plants with roots that reach deep into the soil (7 to 24 inches). Water features, such as small ponds, are included in some. In contrast, extensive roofs are designed to be self-sustaining, with 1.6 to 5 inches of soil and only once-yearly weeding. If the roof is difficult to access, a large roof is often the best option.
What Is A Green Roof
An extensive green roof is more like a rooftop garden, requiring a lot of work, irrigation, and feeding to keep plants with roots that reach deep into the soil (7 to 24 inches). Water features, such as small ponds, are included in some. In contrast, extensive roofs are designed to be self-sustaining, with 1.6 to 5 inches of soil and only once-yearly weeding. If the roof is difficult to access, a large roof is often the best option.
Here are four reasons to install a living roof:
Decreases bills and raises the value of the building
Although installing a green roof on a building can be costly, the benefits provided by the green roof should result in future financial savings, such as reduced energy bills and roof maintenance costs. A building with a green roof has also been found to have a higher rental value than nearby buildings.
Enhances the appearance of a property
Green roofs can host a wide range of plants, from succulent Sedums to floral perennials and even dwarf trees, depending on the depth of the substrate. All of this vegetation enhances the appearance of a structure from both the exterior and the inside.
Energy efficiency
Installing a green roof can dramatically reduce energy expenses, which should appeal to ecologically conscious households. Furthermore, by allowing a garden of fruits, veggies, and edible plants to grow on your roof, you and your family can save money on groceries as well as time and energy. This is especially true for people who live in urban areas with limited green space.
Reduce Rainwater runoff
If you live in an area with a lot of rain, a green roof is a great option. This is due to the fact that it can assist in catching and reducing rainwater flow. Too much rainwater runoff can penetrate into the earth and produce erosion, which is harmful to housing foundations. Not only that, but too much runoff can damage the plants in the area. Because green roofs are covered in plants, the existing leaves, roots, and soil allow water to evaporate and return to the atmosphere rather than fall to the ground surrounding your home.
