Enhancing Urban Spaces: Choosing the Right Plants and the Right Systems for Green Roofs in the UK

In an age where sustainability and environmental consciousness are at the forefront of design, green roofs have emerged as a remarkable solution that harmoniously marries architecture and nature. Green roofs, also known as living roofs or eco-roofs, involve the strategic cultivation of vegetation on top buildings, transforming traditional rooftops into thriving ecosystems. As DANOSA UK, we recognise the importance of green roofs in enhancing the urban landscape and their pivotal role in promoting healthier environments.

Selecting the Right Plants for Your UK Green Roof

When it comes to establishing a flourishing green roof in the UK, careful consideration of plant species is crucial. The UK’s climate, characterised by mild winters and warm summers, poses both opportunities and challenges for plant selection. Here are some plant types that are well-suited for thriving green roofs in the UK:

1. Sedum and Sempervivum: These drought-tolerant succulents are often the go-to choice for green roofs due to their adaptability to various climates. They require minimal maintenance, have shallow roots, and can survive in harsh conditions.
2. Wildflowers: Native wildflowers like meadow cranesbill, oxeye daisy, and yarrow are ideal for promoting local biodiversity. They attract pollinators and offer a vibrant burst of colour during the growing season.
3. Grasses: Ornamental grasses such as Festuca and Carex are hardy choices that provide texture and movement to the green roof. They also contribute to stormwater management by efficiently absorbing excess rainwater.
4. Herbs: Low-growing herbs like thyme and oregano are not only aromatic but also resilient. They can withstand wind exposure and contribute to a visually appealing, fragrant rooftop garden.
5. Alpines: Plants from alpine regions, like alpine aster and alpine forget-me-not, are well-suited for UK green roofs due to their ability to thrive in rocky, well-draining conditions.
6. Native Shrubs: Compact native shrubs such as heather and juniper can be strategically placed to add height and structure to the green roof while supporting local wildlife.

Selecting a DANOSA Green Roof System

As manufacturers of construction waterproofing solutions, we have a range of systems for establishing green roofs with specialised products designed especially for living roofs or areas where planting exists. For the green roof itself, we supply either pre-established modular trays or bespoke built up systems:

1. POLYDAN Reinforced Bitumen Membranes for green roofs: Discover the bitumen felt solution for green roofs with our versatile POLYDAN® Reinforced Bituminous Membranes. The GARDEN variant of POLYDAN® has an anti-root modification designed for living roof systems or where planting exists.
2. DURADAN Structural Hot Melt for green roofs: When it comes to ensuring the longevity and effectiveness of green roofs, DURADAN® Hot Melt Structural Waterproofing is an exceptional solution; designed to perform for the entire service life of a building.
3. DANOPOL Single Ply for green roofs: DANOPOL® PVC Single Ply emerges as an excellent choice for Green Roof systems due to its tailored composition and qualities. All DANOPOL® membranes are rootresistant and rot proof as standard.
4. DANOFORCE Cold Applied Liquid Waterproofing for green roofs: DANOFORCE® Cold-Applied Liquid Waterproofing proves advantageous for Green Roof Systems due to its seamless application; the liquid composition allows DANOFORCE® to conform to the contours of the roof, ensuring a watertight seal even in complex areas. The lightweight nature of liquid systems minimises the structural load, making DANOFORCE® a great choice for sustainable and thriving Green Roof systems.

The Green Roof Advantage

Green roofs offer a myriad of benefits that extend beyond mere aesthetics. These innovative installations play a crucial role in improving urban environments by addressing various challenges that cities face today. Here are some of the key advantages of green roofs:

1. Enhanced Thermal Performance: Green roofs act as natural insulators, reducing heat transfer between the building and the surrounding environment. This helps regulate indoor temperatures, leading to energy savings on heating and cooling.
2. Stormwater Management: By absorbing rainwater and slowing its release, green roofs mitigate the burden on stormwater systems, thereby reducing the risk of flooding and erosion.
3. Improved Air Quality: Plants on green roofs absorb pollutants and release oxygen, contributing to cleaner and healthier urban air.
4. Biodiversity Support: These installations create habitat opportunities for birds, insects, and other wildlife that might otherwise struggle to find space in densely populated cities.
5. Noise Reduction: Green roofs have sound-absorbing qualities, helping to diminish urban noise pollution and creating more peaceful environments.
6. Aesthetic Appeal: The visual impact of lush greenery against the backdrop of concrete jungles is unparalleled. Green roofs add charm and character to buildings while integrating seamlessly with the surrounding landscape.
