Disadvantages You Should Know

While it is highly advantageous, green roofs benefits aren’t immune from disadvantages. Living roofs require more than just a dedicated team of gardeners and retainers. Additionally, they require the following physical and qualitative improvements to install and function successfully.

Additional Building Weight Reinforcement
