Maintenance for a living roof needs to be considered from the outset. There is no such thing as a 'no' maintenance roof, green or otherwise. All new commercial buildings are required to have roof and gutter checks twice a year and an extensive green roof can be designed to align with this requirement. The maintenance required will depend on the desired outcome for your green roof.

Maintenance for Extensive Sedum Green Roofs
We recommend biannual visits to our sedum blanket or plug plant roofs to clear any weed infestation, and one application of fertiliser in the early spring, in time for the growing season. Drainage outlets and inspection chambers cleared of vegetation, as with any roof. Ensure riverstone perimeters are clear of dead and live plants. Sedum roofs should maintain their lush, and healthy sedum coverage. Infestations of grass and other weeds will soon die off due to insufficient substrate depth and become unsightly.
Maintenance for Biodiverse Roofs
Biodiverse roofs are generally seen to have lower-maintenance demands, but will still require a visit once or twice a year to cut and remove the seasons growth. This encourages the spread of seed for the next season and removes the dead unsightly flower heads. Drainage channel and gutter clearance to remove any unwanted debris or leaf litter will also be carried out on regular maintenance visits.
The beauty of a Biodiverse living roof is observing the natural progression of the roof through the seasons and over many years. From one season to the next different plants will dominate and subside as the roof finds a balance with its environmental surroundings.
Maintenance for Roof Level Landscapes
Most semi intensive or intensive green roofs are designed with aesthetic appeal or the functionality of normal garden or recreational area which will dictate a more intensive maintenance regime, as would be required in most gardens.
Access to a water point is essential during the establishment stage of most green roof, especially if installation coincides with the hotter dryer Summer months (June- Aug). We suggest on an extensive sedum green roofs a permanent irrigation system is not necessary, but consideration must be paid to the roof and supplementary watering if periods of prolonged drought (2 weeks) occur. The deeper the substrate used the more moisture it can hold to ensure plant survival during dry periods.

Green roofs are said to have originated as far back as the Babylon Gardens, where specialist irrigation systems were used to keep the vegetation lush. Other notable historical uses of green roofs are in Scandinavia, where traditional sod or turf roofs were used for insulation and camouflage.
The modern day green roof originated in Germany in the 1970s. Serious storm water runoff needed a solution and the modern green roof was born. Now with advances in technology green roofs offer more benefits than ever before and prove to be a great alternative to standard roofing.
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.
BREEAM stands for Building Research Establishment Environmental Assessment Method and essentially sets the standard for the best practice in design for large scale developments. It is used to assess the environmental performance of buildings and communities. The addition of a green roof can increase the building’s BREEAM rating by making the building more environmentally friendly. You can learn more about BREEAM and green roofs on our Downloads page.
Yes. Green Roofs are 'Low-Maintenance' not 'No-Maintenance'. Green roof maintenance is generally a very simple process. They are designed so that they will not require endless hours spent on the roof in order to keep them looking at their best. Each type of green roof brings many different benefits to the occupants, the owners and the roof itself, so a little time maintaining the system is advantageous in the long run.
The amount of maintenance needed depends of the type of green roof installed. Sedum roofs require little maintenance; clearing gutters periodically and occasional weeding to clear unwanted self-seeding species are recommended. Biodiverse roofs are designed to be left and to be as natural as possible so maintenance is again minimal with just periodic gutter clearing of organic matter. Wildflower roofs require more maintenance and may need strimming once a year in autumn. We recommend irrigation systems on all steeply sloped systems to ensure they remain at their optimum throughout hot spells of weather. Sky Garden offers a full maintenance package which includes two site visits a year where gutters will be cleared, fertiliser applied, any weeds removed, strimming of vegetation is undertaken and vegetation barriers and fire breaks are cleared of any unwanted vegetation.
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.
