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 butterfiles, 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 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 run off.  Next a layer of growing medium is installed, followed by a pre-grown sedum blanket.  

Self assembly of green roofs

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

Pricing

All pricing is inclusive of VAT and is based upon the standard floor area.  Just ask us for a quote.

Green 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 green 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 yearWhen our team install we aim for a 95% coverage, bare patches will soon be covered as the sedum grows and establishes itself

Miss Watson, Bristol

“ You recently installed a garden building for us in Wells. It is now fully up and running as a workshop and my husband has spent many happy hours there already on various DIY projects. On your recommendation we used Thorndown Paint which was excellent - beautiful colours (Sedge Green), easy to apply and a lovely finish. You will see from the photos that this building looks as though it was meant to be here, nestled under the shade of a silver birch…”
