How To Maintain Your Green Roof
Green, living roofs are designed to be very low maintenance, with only a few simple tasks needed throughout the year. The main roof maintenance requirements involve checking the surface two or three times a year to keep the vegetation healthy and attractive.
When installing your sedum roof, it is important to use our Sedum Care products during the early stages. These products provide the nutrients your sedum plants need to take root and grow into a strong, thriving living roof. Regular watering is not usually necessary once the plants are established, as sedum is a hardy species that can tolerate different weather conditions.
Twice a year, usually in April and September, you should remove any weeds that may have appeared and inspect the drainage outlets to make sure they are clear. The maintenance requirements for sedum roofs and intensive green roofs are quite minimal compared to traditional roof gardens, and the plants are tough enough to be walked on briefly while you carry out these checks.

Roof Inspection
We recommend you inspect your Sedum roof at least twice a year, usually in Spring and Autumn. You’ll be checking for weeds and seeds carried by the wind and removing leaves and moss to ensure gutters and drains are free flowing. To encourage a healthy habitat and to strengthen the natural biodiversity of the roof, we do not recommend the use of chemical pesticides. You may need to inspect your roof and the guttering more regularly if you live in a particularly green and leafy area.
Fertilization
To cultivate healthy, strong plant growth and to ensure an even supply of nutrients you should fertilise your sedum roof twice a year (preferably in late April and early September). We offer a range of mineral and organic fertilisers. To find out more, download our maintenance guide from the link above
Watering
A well-rooted sedum roof generally does not require any additional water, unless experiencing extreme, continuous hot and dry weather conditions.
