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.

How do green roofs affect building temperature?

Green roofs have a significant impact on building temperatures:
  • Insulation: The layers of vegetation and growing medium act as insulation, reducing heat transfer through the roof.
  • Evapotranspiration: Plants release moisture, creating a cooling effect on the roof surface.
  • Shade: The plant canopy provides shade, reducing the amount of direct sunlight hitting the roof.
This results in a cooler building in summer and a warmer building in winter, improving energy efficiency and reducing heating and cooling costs.

Can I have a green roof on a sloped roof?

Yes, green roofs can be installed on sloped roofs, but special considerations are needed:
  • Slope Stability: Ensure the slope is stable enough to support the green roof system. Steeper slopes might require additional structural reinforcement or specialized retaining systems to prevent soil erosion.
  • Drainage: Design a drainage system that effectively handles water runoff on the slope.
  • Plant Selection: Choose plants that are well-suited for sloped conditions and can tolerate the specific sun exposure and drainage patterns of the roof.
A qualified green roof installer experienced in sloped applications can provide appropriate solutions.

What is the difference between intensive and extensive green roofs?

The main difference between intensive and extensive green roofs lies in their depth, planting, and maintenance:
Extensive Green Roofs:
  • Shallower soil depth (typically less than 150mm)
  • Use drought-tolerant, low-maintenance plants like sedums, grasses, and herbs.
  • Lighter weight, requiring less structural support.
  • Not intended for regular foot traffic.
Intensive Green Roofs:
  • Deeper soil depth (150mm or more)
  • Accommodate a wider variety of plants, including shrubs and small trees.
  • Heavier, requiring more structural support.
  • Can be designed for recreational use and foot traffic.

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.
