A green roof instantly brings life, color, and tranquility to any space. Where there was once a grey roof, a lush green oasis emerges in just one day, evolving with the seasons. The carefully pre-grown Sedum plants from Covergreen® immediately grow densely, making the roof look full, uniform, and well-kept from the very first moment.
Besides its natural appearance, a Sedum roof also offers functional benefits. It provides cooling in summer and retains warmth better in winter. At the same time, it buffers rainwater, reduces peak load on the sewage system, and protects the roofing material from sun and temperature fluctuations. As a result, a green roof extends the roof’s lifespan and contributes to a healthier indoor climate.
What makes the Covergreen® system truly unique is that all the layers a green roof needs are combined into one smart cassette. We deliver a ready-to-install system that’s immediately usable and easy to relocate if necessary.
A Sedum roof is more than just a green eye-catcher; it’s a smart, sustainable solution for modern living and working environments.
Climate adaptive: Sedum absorbs rainwater and temporarily retains it. This helps prevent flooding and reduces pressure on drainage systems during heavy rainfall. The plants also provide cooling in summer and insulation in winter, helping maintain a more stable indoor climate.
Instant green result: Covergreen® delivers fully pre-grown cassettes with a mix of resilient Sedum species. This means the roof looks lush and green from day one — no bare spots, no waiting period.
Easy installation: The modular Sedum cassettes are ready for immediate use and simple to install. Thanks to the integrated layers, no complex roof construction is required. This makes the system suitable for both professional installation and DIY applications.
Low maintenance: Sedum plants are succulents that store water in their leaves. They tolerate sun, wind, and drought exceptionally well and need minimal water or nutrients. One or two checks per year are often enough to keep the roof looking great.
Long lifespan: Since Sedum protects the roof membrane from UV radiation, heat, and temperature fluctuations, it significantly extends the roof’s lifetime.
While traditional green roofs are built layer by layer, Covergreen® has completely simplified the process.
Our Sedum cassette contains everything a green roof needs in one compact package: an integrated drainage layer, a substrate layer, and a fully rooted Sedum mat.
The cassette functions as a small ecological unit:
Because all layers are fixed parts of the cassette, installation is simplified. Just place the panels side by side — click, slide, or fit them snugly together — and within a short time, you’ll have a fully covered Sedum roof.
The system is lightweight, durable, and cleverly designed: the trays do not root together, which means they can easily be lifted and replaced. This makes roof maintenance simple. Need to repair something? Just lift the cassettes, perform the work, and place them back — quick, clean, and without damaging the green roof.
The Covergreen® Sedum roof cassette is suitable for almost any flat or slightly sloped roof. Thanks to its light weight and integrated layers, the system can be installed on many existing roofs without structural modifications.
Whether it’s a home, garage, carport, garden shed, or commercial building, a Sedum roof provides a green, vibrant appearance everywhere. The modular design makes it easy to install on both small and large surfaces, with an instantly uniform result.
Sedum plants thrive in full sun but also grow well in partial shade. They adapt easily to different climates: in hot, dry conditions, their leaves turn reddish to protect themselves, and in moist or shaded environments, they regain a fresh green hue. This means the green roof remains attractive all year long, with natural color shifts that follow the seasons.
A green roof and solar panels form an ideal combination. The Sedum plants help cool the roof surface, keeping the temperature around the panels lower, which can increase efficiency by up to 10%. Additionally, the green roof buffers rainwater, reduces glare, and extends the life of the roof membrane.
Each cassette contains a carefully selected mix of succulents (Sedum species), cultivated in our own greenhouses on vegetation mats. These plants are resilient to wind, sun, rain, and drought, and together they create a lively, colorful cover that changes throughout the year.
The mix includes various species such as Sedum Delosperma, Sedum Sexangulare, Sedum Reflexum, Sedum Floriferum, Sedum Album (Minor & Murale), Sedum Spurium, Sedum Acre, Sedum Cauticolum, and Sedum Lydium.
For larger vegetation mats, species such as Sedum Kamtschaticum, Sedum Stoloniferum, Sedum Hybridum, Sedum Coccineum, and Sedum Floriferum are also used.
Each species contributes to a unique and diverse whole, with blooms in various colors and periods. From fresh green tones in spring to warm red and yellow hues in summer and autumn. The Sedum mix attracts bees, butterflies, and other beneficial insects, making the roof not only beautiful but also valuable for biodiversity.
The strength of Sedum lies in its leaves: the thick, fleshy foliage stores water, allowing the plant to survive even during dry periods. Many species are also self-healing — broken leaves root again and grow into new plants. This ensures the roof remains lush and healthy without intensive maintenance.
With this robust and self-regulating vegetation, the Covergreen® Sedum roof stays healthy, strong, and low-maintenance for many years to come.
