Greenrooftops is a UK grower and supplier of simple, low-maintenance green roof systems for homes, sheds, garden rooms and other outbuildings. Founded by grower Tim Riley, the brand brings growing expertise to roof projects by preparing its sedum modules on the farm, so customers receive ready-to-install products without needing specialist skills. Its fully grown sedum trays click together and include drainage, a water reservoir and growing substrate, providing immediate coverage and colour.

The trays feature 16 hardy sedum varieties selected for British and Northern European conditions, with blooms that change through the warmer months and can support bees and butterflies. Greenrooftops also sells sedum blankets, complete green roof systems, underlay matting, aluminium edge trims and corners, slow-release fertiliser and pebbles. Products are delivered across the UK, and the company offers guidance on roof maintenance and sedum varieties.

The system was selected for the Grand Designs Wirral project in 2016. Greenrooftops aims to make adding a living roof more accessible, practical and straightforward for householders and garden-building owners
