  • Popular FAQs

    • Can I still have solar panels?
      Yes. Green roofs can be designed to fit around solar panels or the panels can fit on top of the roof. This can not only increase the efficiency of the solar panels, but the shade created by the solar panels can increase biodiversity of the underlying green roof. Special care must be taken when selecting plants to be installed in the shaded areas to ensure they grow well in low light conditions.
    • Do I need planning permission?
      Most green roofs can be installed with no planning permission, however some do require it. This depends on the location, type of building, height etc and should be consulted before installation. Green roofs are increasingly mandatory for new developments. Planning consent can stipulate that the area must blend into the surrounding landscape or mimic the water runoff of nearby Greenfield sites. Green roofs can allow constructors to overcome these terms.
    • Can I choose what plants to have?
      Sky Garden’s seed and blanket mixes have been specifically designed to work well on green roofs. The thin, low nutrient substrate and exposure can make it hard for some plants to grow well. However we do offer bespoke plants and systems, especially on intensive green roofs. For a full quote and design brief for a bespoke system please contact our sales team.
    • Do I need to water my green roof?
      Sedum is used because it is drought resistant and very hardy. Under normal circumstances the roof should not need regular watering. However, live material must be irrigated immediately following installation. This irrigation must continue in the first few months following installation and again in especially hot and dry periods. Sky Garden recommends full saturation of the system once a week in these periods.
    • How much does a green roof cost?
      Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
