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.
