Green Shield Systems
Green Shield is Garland UK’s range of extensive green roofing systems, combining a proven waterproofing system with a vegetated roof build-up that incorporates drainage, growing medium, and carefully selected planting.
Extensive green roof systems for refurbishment and new build
Green Shield combines Garland UK’s waterproofing system with an extensive vegetated roof build-up, creating a roofing solution that incorporates drainage, growing medium, and carefully selected planting.
The system is suited to projects where stormwater attenuation, biodiversity enhancement, and roof-level environmental objectives form part of the design strategy, while maintaining the primary function of the waterproofing system.

Extensive Green Roofing System Applications
Green Shield systems support diverse environmental priorities across commercial, residential,
education, and public sector developments.
Biodiversity enhancement
The sedum planting layer contributes to biodiversity objectives and can support planning and ecological strategies.
Stormwater management
The substrate and vegetation layer retain and release rainfall gradually, contributing to the management of roof-level surface water.
Thermal performance
The vegetated roof build-up helps moderate temperature fluctuations across the roof assembly, contributing to the performance of the waterproofing system.
Waterproofing protection
The growing medium and vegetation layer provide additional protection from direct UV exposure and thermal cycling across the waterproofing system.
Green Shield Extensive Green Roofing System Configurations
Choosing the right configuration within Garland UK’s extensive green roofing systems depends on the project’s biodiversity objectives, drainage requirements, and maintenance strategy. The Green Shield range includes options for renewable energy integration, low-maintenance sedum planting, wildflower habitat creation, and enhanced stormwater attenuation, allowing the specification to align with both environmental targets and the building’s roof construction. A Garland UK Technical Manager can help identify the right Green Shield configuration for the project.
Solar PV
Combines an extensive sedum roof with integrated solar PV, allowing renewable energy generation and vegetated roof construction within a single roof build-up.
- Integrated extensive green roof and solar PV
- Elevated mounting system above vegetation
- Compatible with coordinated roof design
Sedum
An extensive green roof system using established sedum planting, providing a lightweight vegetated roof suitable for a wide range of refurbishment and new-build applications.
- Extensive sedum planting system
- Lightweight roof build-up
- Low maintenance planting strategy
Wildflower
An extensive green roof system incorporating a selected wildflower planting mix, specified where biodiversity objectives and habitat creation form part of the project design.
- Native and perennial planting selection
- Supports biodiversity and ecological strategies
- Extensive roof build-up with managed maintenance
Storm Defence
Storm Defence combines an extensive green roof with a blue roof attenuation layer, temporarily storing rainfall and releasing it at a controlled rate as part of the building’s drainage strategy.
- Blue roof attenuation beneath the vegetated layer
- Controlled discharge to the drainage network
- Designed for developments with surface water constraints
