Green Roofs
Supporting nature and people with vegetated areas on flat roofs. Better for everyone and better for the environment.
Green roofs for new build construction and existing buildings
Green roofs deliver varying levels of benefits to a building, people, the environment, and sustainability. A green roof can be advanced with a solar PV array for renewable energy generation and a blue roof to assist in the prevention of localised flooding for stormwater attenuation.
A green roof is specified for many different reasons encompassing increasing outdoor spaces to enhance the building's use, satisfy planning conditions, meet targets for retaining and supporting biodiversity and net zero, and oppose climate change.
On retrofit projects weight loading is a key consideration and some extensive green roofs can be confirmed as suitable without additional support to the roof structure.
We have adopted the new Code for Construction Product Information (CCPI) across our roofing portfolio to have information assessed for accuracy and clarity to ensure specifiers can rely on the information when selecting a Bauder blue roof solution.

Six steps is all it takes
Brief and consultation
You give us your remit either at your office or on site. We will discuss the green roof project; site suitability, level of access required, falls and drainage, weight loadings, performance expectations, preferred system application, your budget and how the programme of works can be formulated.
Roof review
Upon determining that a green roof is a suitable and practical addition to your building we will perform a detailed appraisal of all roof areas to fully assess the design considerations. Once the vegetation finish has been decided the structural and design considerations, and green roof components can they be proposed.
Report, design and specification service
Designing to protect the building's construction and flat roof waterproofing is vital when delivering a green roof as many additional forces can affect the structure. The detailed report and specification package you will receive takes into account these factors and not only answers your original brief but also meets the needs of the building.
Contractor selection
The Bauder approved contractors best placed to deliver your green roof will competitively price and tender for your project. Our national network of contractors undergo a rigorous selection process and their installers are trained specifically in the application of our systems, so you are ensured expert installation.
Installation of the green roof solution
Once the Bauder approved contractor has been appointed, a pre-contract meeting will make sure that the project delivery is well coordinated. The works are closely monitored by Bauder site technicians with regular inspections and 'live' time reports to ensure quality and waterproof integrity of the roof.
Sign off, guarantee and maintenance
A full final inspection is completed on the works by our site technician team following rigorous approval criteria before the guarantee is issued. Our comprehensive range of guarantee packages fulfil cover requirements for the project (dependent on system/product selection).
Green roof solutions
A Bauder green roof combines the finished planting scheme with its supportive components and a secure waterproofing system all covered by a single guarantee.
We have different system categories depending on the green roof finish you want to achieve, and all can be specified in unison on one roof area. Choose from:
- BauderEXTENSIVE - Lightweight, low maintenance, vegetation swathes for instant greening of the roof
- BauderBIODIVERSE - Creating substitute habitats for flora, insects and fauna
- BauderINTENSIVE - Accessible rooftop gardens and recreational spaces
- BauderHARDSCAPE - Pedestrian and vehicular access areas or for a full roof area
BauderEXTENSIVE
Extensive green roofs are designed to be low-maintenance, lightweight systems with no general access. Typically, they have thin layers of substrate to keep depth and weight to a minimum. A substrate-based green roof will often incorporate a mixed vegetation scheme chosen to suit the project and location. Extensive green roofs are delivered for a variety of reasons, the most popular being for biodiversity and meeting a Biodiversity Action Plan (BAP).
BauderBIODIVERSE
A biodiverse roof aims to replicate as far as is practical the ecological requirements of the local area. The natural habitats created are designed to support a variety of plants, birds, animals and invertebrates. The careful design and construction of these habitats is key to conforming to the local Biodiversity Action Plan (BAP) or the site's Urban Greening Factor (UGF) commitment.
BauderINTENSIVE
Designed for publicly accessed rooftops and podiums that need to have high-quality, reliable landscape build ups. Garden planting schemes require greater depths of substrate and the overall weight of the solution dictates the construction of the supporting structure and the green roof components required to sustain the vegetation.
BauderHARDSCAPE
Used predominantly on courtyard podiums with heavy vehicular access where keeping the total build-up height of the system and providing a completely flat paved surface is important in helping reduce construction costs. This can be particularly effective when used to provide a permeable paving system.
Including a photovoltaic solution or blue roof
Suitable for extensive green roofs, and blue roofs when a vegetated finish is specified, our BauderSOLAR G LIGHT PV solution uses the substrate as the ballasting mechanism to secure the array to the roof.
We also have our BauderSOLAR F flat roof solar PV solution where a green roof finish isn't required.
The BauderBLUE STORMsub is a blue roof with a vegetated finish can be specified for SuDS and stormwater attenuation.
Additional support
Our ethos is to support you through every stage of your project, from concept and design to system selection, installation, inspection, sign-off, guarantee and beyond. We don't just supply products to a distributor - we collaborate with you and care about the success of the projects you deliver.
