Green Roofing Design, Installation and Maintenance Specialists

Green and brown roofing is often referred to as living roofs and they have become much more popular in recent years. Many now consider them a viable commercial roofing option that not only provides the required functionality of roofing but also offers environmental benefits. Green roofs come in a variety of types that are designed to improve the visual appearance of a building or particular area of a building and they are often used as a feature on terraces, podiums or similar environments. Brown roofs typically have a less complicated structure and offer a wide range of environmental benefits that serve the community and wildlife.

Green roofs are typically used for many types of commercial buildings on substrates such as podiums, large terraces and areas that need waterproofing. They effectively seal and waterproof commercial spaces while also adding a unique visual appearance providing significant environmental benefits. These roofing systems are very efficient in maintaining consistent temperature levels inside while also acting as a shield against effects from the sun or other weather elements. Additionally they have excellent water retention capabilities that range anywhere from 40% up to a maximum of 95% retention based on the exact style and application used.

  • Shields the building or area from the sun and other weather elements
