We've compiled some valuable information to help you decide whether a green roof is right for you! Also, we'll cover how to maintain your green roof.

Costs of a green roof

The costs of a green roof depend on its size and how much vegetation is required. Roofs that are not structurally reinforced will cost less than those that need to be strengthened. In addition to plants, green roofs can also feature decorative elements such as benches and water fountains. Although green roofs come in many forms and varieties, costs vary widely depending on the materials used and the number of plants per square foot. There are many benefits of having a green roof, so it's essential to weigh the benefits and disadvantages of this type of roof before making the final decision.

Benefits of a green roof

The use of a green roof has many benefits. First, they reduce air pollution. Many of the pollutants in the air are harmful to human health, causing symptoms such as asthma and allergic reactions. In addition, green roofs are great for regulating temperature, which helps reduce energy costs year-round. Another benefit is that they reduce the risk of deforestation, which results in decreased vegetation. Moreover, green roofs can eliminate the need for rain gutters and reduce the overall maintenance of a building.

Maintenance requirements of a green roof

While extensive green roofs require little maintenance, intensive rooftops require more attention. Annual inspections will suffice for the first two years. Spring and autumn maintenance is recommended for the third year. Depending on the green roof's characteristics, it might also require irrigation or other mechanical means. In some cases, the maintenance requirements can be automated. Ultimately, the benefits outweigh the costs. If you're considering a green roof for your commercial property, the benefits are likely to outweigh the maintenance requirements.

Plants that can be used on a green roof

Succulent plants are an excellent choice for green roofs. These plants store excess water and minimize transpiration. Popular succulents include Sedum, Euphorbia, Sempervivum, and Delosperma. Listed below are some recommended species and growers. Check out this article, "16 Spectacular Green Roofs Around World," for some great ideas!
