Flat roof 0-5°
Flat roofs are ideal as green roof. The system structure for a flat, water-retaining green roof consists of a drainage layer with filterfleece, extensive roof garden substrate, and a vegetation blanket.
Green Roof
There is often little space for greenery in urban areas. An ideal solution for this is greenery on the roof. A green roof is not only appealing to look at, it also offers many other advantages, such as water buffering, temperature regulation, sound insulation, air purification and it also encourages biodiversity. It's not just a Sedum roof that can be attractive, have you considered herbs on your roof, or vegetation specially selected to attract bees and butterflies? We are happy to advise you about the best application for your project.
Green Roof for:
System structures
Shallow pitched roof 5-25°
The structure of a shallow pitched green roof differs slightly from the structure of a flat roof. Because water runs off the roof more quickly, a thicker substrate layer is needed. The substrate gives the correct dose of nutrition to the plants and so ensures your green roof is indeed green.
Steeply pitched roof 25-45°
Sempergreen has the perfect solution for pitched roofs. The Sedum-mix blanket type T has plastic reinforcement top and bottom. This makes this vegetation blanket – in combination with the correct system structure – very suitable for (steeply) pitched applications. Read here about how you can transform your pitched roof into a sustainable green roof.
Lightweight
Sometimes a flat roof support structure requires a lightweight green roof. Our special lightweight structure for flat roofs transforms your grey roof, with a pitch of 0 to 15 degrees, into a sustainable green roof almost instantly.
Biodiverse roof
When construction is underway, the ecosystem is disturbed. With a biodiverse roof you can contribute to maintaining biodiversity in the urban environment. Join Sempergreen and do your part to counter bee mortality, opt for a green roof with a Bees & Butterflies blanket.
