Green Roof Installation FAQs

Looking for reliable information about green roof installations? Find answers to common questions and get connected with experienced green roof installers in UK.

What is the difference between a green roof and a roof garden?

The terms 'green roof' and 'roof garden' are often used interchangeably, but there is a subtle distinction:
Green Roof: Primarily designed for environmental benefits, such as stormwater management, energy efficiency, and improved air quality. May have limited access and be primarily for aesthetic purposes.
Roof Garden: Primarily designed for recreational use, featuring walkways, seating areas, and a wider variety of plants. Requires more structural support and maintenance.
Essentially, a roof garden is a type of green roof designed for active use, while a green roof may or may not be accessible for recreation.

How do I maintain a green roof?

Green roofs require regular maintenance to thrive. The level of maintenance depends on the type of green roof system and the chosen plants. General maintenance tasks include:
  • Watering: During dry periods, supplemental watering might be necessary, especially during the establishment phase of the plants.
  • Fertilizing: Regular fertilization ensures the plants have the nutrients they need for healthy growth.
  • Weeding: Remove any weeds that may sprout up in the growing medium.
  • Pruning: Prune plants as needed to maintain their shape and prevent overgrowth.
  • Inspection: Inspect the roof and drainage system regularly for any signs of leaks or blockages.
Consider a maintenance contract with your green roof installer or a landscaping company specializing in rooftop gardens to ensure proper care.

What are the different types of green roofs?

Green roofs are categorized into two main types:
  • Extensive Green Roofs: Feature shallow soil depths (typically 100mm or less) and low-maintenance plants like sedums, grasses, and herbs. They are lightweight and require minimal structural support, making them suitable for a wide range of buildings.
  • Intensive Green Roofs: Have deeper soil depths (150mm or more) and can accommodate a wider variety of plants, including shrubs and small trees. They require more structural support and maintenance, often resembling traditional gardens.
The choice between intensive and extensive depends on the roof's structural capacity, budget, and desired aesthetic and functionality.

How do I know if my roof can support a green roof?

Before installing a green roof, it's essential to have a structural engineer assess your roof's load-bearing capacity to ensure it can handle the additional weight. The weight of a green roof can vary depending on the type of system, the soil depth, and the saturation level of the growing medium. The structural engineer will evaluate the roof's design, framing, and supporting elements to determine if it needs reinforcement or modifications to accommodate the green roof's weight.
