Green roofs can be used in many situations from bin store or shed roofs, through to full domestic and commercial buildings and garden structures. It is recommended that the roof should support at least 47kg-80kgm2 additional weight depending on the design.

Measure the total space to be covered by the green roof including factors such as access, drainage and any potential obstructions such as vents, chimneys or solar panels. Your sedum should equate to this entire space allowing for some overlap and waste to ensure full coverage during installation. More advice can be found on our helpful guide.

If in doubt, please contact us and one of our team will come back to you as quickly as possible.

Once you have the complete measurements and design in mind, its time to order. Using the Sedum Supply online store you can select all the elements required to create your green roof or wall. For flat or large roof installations, our sedum roof packs contain everything you need while our SMART box modular system provides a complete solution in a slot tray style preferable for square or rectangle designs with little obstacles and hard to reach areas.

Complete your project with our aluminium edging system and additional pebble packs if required. We will work with you to ensure smooth delivery to your chosen location.

Before beginning installation, ensure your roof if fully clean and in good condition. Additional waterproofing membrane is advised to fully protect the roof structure from water damage. Once complete, cover the roof with an effective drainage layer to prevent water buildup. Follow this with a layer of lightweight growing medium providing good water retention to support sedum plants. Applied as an even layer across the entire roof space, it will support the health of sedum or wildflower plants.

SMART box installations due to modular design do not require installation of growing medium or drainage layer as these are part of the product design. Simple slot each module into place once the roof is fully prepared for installation.

Our sedum plants are selected due to their performance potential and shallow root. There are up to 12 – 14 varieties of sedum within our range and we can offer advice on the best varieties to meet your project needs. Did you know you can even add wildflower seeds to your sedum roof to add more seasonal colour and biodiversity? Sedum turf is placed across the roof similar to lawn turn. Once in place and established the green roof will become a blanket of colour adjusting throughout the seasons.

Once planted, we recommend watering the entire roof to aid plant health and monitor daily for the first week in case required additional watering – or longer during hotter, drier periods. Once established, the roof will only require regular checks for any potential issues such as drainage, and maintain with some pruning, fertiliser or additional watering as required.
