Blue roofs tend to occur on large open roof spaces with high capture capacity, normally seen in commercial development, with wide gutters and a robust waterproof tanking membrane.
The Sky Garden blue roof system, when integrated with a green roof, can effectively capture, treat, and store water, gradually releasing it into the drainage network. This
makes the Sky Garden blue roof system a valuable component of the comprehensive Sustainable Drainage Systems (SuDS) management for any development.
Our Blue Roof design is fully backed by Professional Indemnity insurance, and we will support you throughout the design process from initial inquiry to installation. Each of our quotations is tailored specifically to the requirements of the development.Features and benefits

Blue roofs are suitable for new build but generally too heavy for refurbishment. Roof pitches up to 15° can be greened but over 15° retention and irrigation are required.
MAINTENANCE
We would recommend that pre-handover inspections and cleaning of all flow control outlets and overflow chambers is carried out. Routine inspections should include:
• Monthly inspections of flow control chambers and overflow chambers extending to quarterly inspections after 6 months.
• Visual inspection of landscaped surfaces and green roof surfaces on an 8-10 week basis extending to 6 monthly inspections after 6 months.
• All silt and debris to be removed from chambers as required and maintenance records kept.
• Full system inspection after major rainfall events. -

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.
-
What is the steepest pitch I can have a green roof on?
Sky Garden’s drainage board and soil retention systems have been specifically designed to be used on steeply sloping roofs. We can offer green roofs on any pitch from flat to vertical and can install green walls.
