Green Roofs

Why choose a green roof?

• Make better use of roof space
  Transform otherwise unused areas into green, functional or recreational spaces.
• Manage stormwater naturally
  Vegetation and growing media retain and delay rainwater, helping reduce pressure on drainage systems.
• Support biodiversity
  Create habitats for plants, insects and other species – particularly valuable in dense urban environments.
• Create better urban environments
  Add greenery to buildings and help create more attractive and liveable surroundings.
• Protect the roof construction
  The green roof build-up protects the waterproofing membrane from direct UV exposure and temperature fluctuations.
• Add value to the building
  Combine reliable waterproofing with attractive, usable roof areas that can enhance the overall value and quality of a development.

Ballasted or green roofs can be used for recreational areas or roof gardens. These solutions give architects and builders a lot of freedom for aesthetic design and contribute to more natural surroundings through the use of pebbles or vegetation. Green areas and roof terraces increase value both for property developers and those who live in or use the buildings. The weight of the ballast requires the load-bearing structure to be engineered for this purpose.

Some types of green roofs commonly used is:

Extensive Green Roofs: These are lightweight and low-maintenance green roofs that typically have a shallow soil depth of around 2-6 inches. They are suitable for industrial buildings due to their cost-effectiveness and ability to handle harsh environmental conditions. Extensive green roofs usually consist of hardy, drought-tolerant plants such as sedums and mosses.

Intensive Green Roofs: Intensive green roofs are more like traditional gardens and can support a wider variety of plants, including shrubs, trees, and even small water features. They require a deeper soil depth, usually 6 inches or more, and can accommodate human activity. However, they are heavier and more expensive to install and maintain compared to extensive green roofs.
