Let it grow: exclusive and sustainable green roofs
As more and more open land is closed in, greenery on roofs is gaining importance as a way of replacing lost natural areas. They extend the durability of the roof membrane and have an equalising effect on the building's climate. They usually consist of low-growing, resilient and low-maintenance wild plants and herbs. We will gladly advise you on extensive roof vegetation and transport the ideal substrate onto your roof.
Colourful and living roof vegetation
We accept delivery of old roof tiles free of charge. They are collected and broken up by a crusher and screened twice a year. The crushed tile granules are mixed with bark compost to create our certified W+A Dachgrün Plus substrate. An ecologically expedient solution!

Our seeding mixes
It is important to choose a suitable seed mix with drought-tolerant indigenous wild herbs, possibly supplemented with sedum shoots. We offer different roof mixtures with various plants. One of the most important attributes after seeding is patience. It takes 4-8 weeks before the first seedlings becomes visible depending on the seeding time and the weather. At least three quarters of the roof surface should be covered by living plants after two vegetation seasons.
