Green roof systems for sustainable design

Complete, layered green roof systems that support biodiversity, manage rainwater and extend roof life.

Green roofing systems. A range designed to suit a wide variety of buildings, budgets and installation methods.

From lightweight extensive roofs and deeper planted systems to integrated biosolar solutions and modular trays for smaller properties, the gRoof range enables green roofing to be specified in a way that suits both structural constraints and project ambitions.

gRoof Eco extensive green roof

gRoof Eco

A lightweight, extensive system where structural capacity, cost and simplicity matter most. Shallow medium, low-maintenance planting, minimal load.

Lightweight, extensive
gRoof Natural wildflower green roof

gRoof Natural

A deeper-planting system for wildflowers, grasses and perennials. More substrate depth, more biodiversity and water retention.

gRoof Biosolar green roof with integrated solar

gRoof Biosolar

Vegetation and photovoltaics in one roof, no penetrations. Surface cooling lifts module efficiency and cuts stormwater runoff.

gRoof Modular tray-based green roof

gRoof Modular

Pre-grown trays for small residential roofs, extensions and outbuildings. Quick, low-disruption installation without a full build-up.

The benefits of green roofing. Measurable performance alongside long-term environmental value.

By combining vegetation with engineered roof build-ups, gRoof transforms unused roof space into a functional asset that supports drainage, durability, biodiversity and building efficiency.

Thermal regulation

Vegetated roofs help regulate roof surface temperatures through shading and evapotranspiration. This decreases heat gain during summer, reduces temperature extremes affecting the waterproofing layer, and enhances internal comfort, especially on flat roofs exposed to direct sunlight.

Biodiversity and ecological value

gRoof systems create valuable habitats in built environments by supporting a wide range of plant species, insects, and pollinators. From low-maintenance sedum roofs to more diverse planted systems, gRoof helps restore ecological functions to roof spaces that would otherwise remain inactive.

Rainwater management

Our green roofs retain and slow the release of rainfall, reducing peak runoff and pressure on drainage systems. Stored water is gradually released through evaporation and controlled discharge, helping to meet sustainable drainage requirements while lowering the risk of surface water overload.

Energy performance

On biosolar installations, vegetation helps cool the surrounding roof surface, which can support photovoltaic efficiency during warmer periods. Combining green roofing with solar generation allows roof areas to deliver both environmental and energy benefits from a single footprint.

Sustainability

gRoof systems support planning objectives related to sustainability, biodiversity net gain, and climate resilience. Whether specified to meet local authority requirements or long-term environmental goals, gRoof offers a practical and scalable pathway to greener building design.

Roof protection

By protecting the waterproofing layer from UV exposure, temperature fluctuations, and mechanical wear, gRoof systems help prolong the roof's lifespan and decrease long-term maintenance requirements. This protective layer enhances durability and reduces the risk of early roof refurbishment.

  • Residential

    Green roofing suits homes, extensions, garages, and multi-plot developments. Our gRoof Modular and Eco systems offer a simple solution for all residential roofing of all sizes.

  • Commercial and industrial

    Flat roofs on commercial and industrial buildings offer significant opportunities for green roofing. Our gRoof systems help manage rainwater, protect roof membranes, and enhance the long-term performance of large, often underused roofs.

  • Education and public sector

    Schools, colleges, universities, and civic buildings increasingly adopt green roofs for sustainability. Green roofs support environmental goals, biodiversity, and long-term roof protection.

  • Healthcare

    Hospitals, clinics, and community buildings benefit from green roofs' thermal regulation, drainage, and aesthetics. In overlooked or visible areas, gRoof systems can boost wellbeing and environmental quality.

  • New build and retrofits

    Allbase green roof systems can be used in new developments or adapted for existing buildings based on structural assessment. Light options enable green roofing during refurbishments, while deeper systems are suitable for new builds from the start.
