Green Roofs

All our flat roof garden buildings are offered with the option of a beautiful, sustainable living green sedum roof.  A green sedum roof will give great pleasure to watch as it grows and develops and is very long-lasting when properly cared for. For garden offices or garden studios, to be used throughout the year, a green roof offers excellent insulation properties, reducing the power required for heating and air-conditioning. A green roof also absorbs rainwater and, importantly, attracts beneficial garden wildlife such as butterflies, ladybirds & bees.

Mr T, from London: "I am delighted with my green roof.  As a professional artist, it is important that my studio has a stable temperature all year round to prevent damage to my work.  The insulation properties have been far better than I imagined".

Design & installation of your green roof

A green roof will need to be specified at the design stage of your garden building to enable us to add any additional strengthening if required.  

Our installation team will install a waterproof membrane (EPDM) with a drainage outlet (ideal for rainwater harvesting). On top of the waterproof membrane, a drainage board with a moisture retentive fleece & weed suppressant is fitted to ensure a steady supply of water to the roots and prevent water runoff.  Next, a layer of growing medium is installed, followed by a pre-grown sedum blanket.  

Self-assembly of green sedum roofs

If you would like to self assemble your building, then we can supply & deliver your green roof anywhere in the UK.

Green Sedum Roof care and maintenance

Your Green Roof will provide an attractive, low maintenance feature for years to come! But it is important to note that a sedum roof thrives in full sun or partial shade. They are not suitable for areas in full shade or under tree canopies.

Watering will be required, especially during periods of dry weather.
A slow-release granular fertiliser applied in Spring is all that is required.
From time to time weeds will sow themselves within the sedum, these are easily removed throughout the year when our team install we aim for a 95% coverage, bare patches will soon be covered as the sedum grows and establishes itself.
