gRoof Eco
A lightweight, extensive system where structural capacity, cost and simplicity matter most. Shallow medium, low-maintenance planting, minimal load.
Lightweight, extensiveGreen roof systems for sustainable design
Complete, layered green roof systems that support biodiversity, manage rainwater and extend roof life.
Living roof system, LeedsSystems
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 Natural
A deeper-planting system for wildflowers, grasses and perennials. More substrate depth, more biodiversity and water retention.
Deep planting, biodiverse
gRoof Biosolar
Vegetation and photovoltaics in one roof, no penetrations. Surface cooling lifts module efficiency and cuts stormwater runoff.
Green and solar
gRoof Modular
Pre-grown trays for small residential roofs, extensions and outbuildings. Quick, low-disruption installation without a full build-up.
Tray-based, domesticgRoof system properties
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.
Services
Installation, maintenance and support. Green roofing delivered with confidence, from planning through to ongoing care.
Allbase's range of green roofing systems is supported by a comprehensive selection of products and services, including advanced liquid-applied roofing solutions, Solar PV systems, technical services, installation, and maintenance plans. This integrated approach ensures gRoof projects can be delivered consistently, efficiently, and with confidence, from initial planning through to ongoing care.
Approved Installers
gRoof systems can be installed by approved roofing contractors experienced in green roof construction and flat roof detailing. Each system is supplied as a complete, coordinated build-up, helping to reduce on-site complexity and ensure consistent installation quality.
Learn moreMaintenance & Aftercare
All our gRoof systems are designed to be low maintenance, with inspection and care requirements tailored to the chosen system and planting type. Regular checks support healthy vegetation growth, clear drainage paths, and long-term roof performance.
