    Why Choose A Modular Green Roof?

    March 24th, 2020

    The introduction of the new improved M-TRAY® modular green roofing system to the UK market has made it easier than ever before to install a green roof.

    This pre-grown sedum green roof product is supplied in easy-to-handle plastic tray units.

    A fully established, mature garden roof system can be installed quickly and easily on difficult-to-access roofs by hand without the mess and disruption associated with traditional extensive green roof systems.

    What Benefits Are Offered By A Modular Green Roof?

    The main advantages of modular over roll-out green roof systems include convenience and speed of installation, futureproofing, and the delivery of instant results.

    All the elements required for a successful green roof have been measured and installed into the M-Tray® modules at the nursery.

    Users can feel confident that the plants, growing medium and filtration components are suitable and compatible, and at the correct level to give strong, healthy growth over the long term.

    The trays are grown for a period of at least 6 months and all will have been through at least one spring growing season; so the plants are well established, healthy and strong, and fully integrated into the substrate (unlike sedum blankets, which are not).

    Mess and disruption are big issues with roll-out systems.

    Moving bags of aggregate-based substrate onto rooftops is fraught with risk – the aggregate goes everywhere and as it is so granular, it can damage waterproofing membranes very easily. Sedum blankets are also supplied rolled up, so the plants get damaged during the transport and installation process.

    This is not the case with the M-Tray® modules.

    A Myriad of Benefits

    Growing plants on your roof may initially sound a little unorthodox, but it presents a myriad of benefits to the modern homeowner, with increased energy efficiency being a primary advantage.

    Offering Energy Efficient Qualities

    Whilst there can be little doubt that the installation of a modular garden roof system can greatly improve the aesthetics of a standard roof, the benefits do not stop there as it green roofs actually offer a variety of benefits including:

    • Increased Roof Lifespan
    • Energy Reduction
    • Reduced Urban Heat Island Effect (UHIE)
    • Increasing Biodiversity and Wildlife
    • Improved Air and Water Quality
    • Reduced Sound Transfer

    The advances made in the design of the new M-Tray® model have created a number of key advantages including:

    • Deeper cavities for extra root growth
    • Optimum drainage leading to stronger plant growth
    • More established vegetation at point of installation
    • More efficient transport and packaging
    • Exactly 4 units per m2
    • Easier to carry trays with smooth handles


    • A closer connection between trays for more seamless plant growth
    • No sharp edges, less risk to the membrane
    • Nothing spills out, less mess
    • Made from recycled plastic with the recycled substrate
    • Less packaging, less waste
    • UK designed and manufactured in the UK

    Our unique M-Tray® has been specifically developed to make sedum roof installation that much easier with minimum disruption to both the plants and the structure it is going onto.
