A green roof is not only an investment in sustainability, but also provides clear financial benefits. You benefit from both short-term and long-term savings and increases in value:
Lower energy costs – natural insulation reduces heating and cooling costs by up to 12% per year.
Longer roof life – vegetation protects against UV rays and temperature fluctuations, extending the life of the roofing material by up to 20 years.
Higher home value – a green roof contributes to a better energy label and a more attractive appearance, which can increase the resale value by 2-4%.
Grants – many municipalities reimburse up to 50% of construction costs….
Ecological benefits green roof
A green roof makes an important contribution to the environment. Vegetation retains rainwater, reducing flooding during peak rainstorms. Plants on the roof filter particulate matter from the air and convert CO₂ into oxygen, making for a cleaner living environment. In addition, a green roof cools the city and increases biodiversity by providing food and hiding places for bees and butterflies.

Comfort & health
In addition to the visible benefits, you’ll notice a green roof indoors. It dampens sounds from outside, making your home or office feel quieter. On hot days, it stays several degrees cooler inside, making you less dependent on air conditioning. This makes for a more stable and healthier indoor climate and greater living comfort throughout the year.
Features of a green roof
A green roof has several properties that determine how it functions and the benefits you experience. It improves insulation, buffers and slows water runoff, and creates a more pleasant indoor climate. There are also practical aspects, such as walkability, drawbacks and proper edge finishing with roof gravel, for example. Together, these features make a green roof a sustainable and comfortable choice.
Frequently asked questions: benefits green roof
A green roof can save up to 12% on energy costs through better insulation. It also extends the life of the roofing material, which delays expensive replacement. With subsidies available for green roofs, the return on investment is even faster.
Plants on the roof collect rainwater, filter particulate matter from the air and provide cooling. Biodiversity also increases as birds and insects find food and hiding places.
Yes, definitely. A green roof acts as a sound absorber and provides a more stable indoor temperature. It stays cooler in the summer, and it retains heat better in the winter.
Many municipalities encourage the construction of green roofs. Often up to 50% of the cost is reimbursed. Check our grants page for current opportunities.
A properly installed green roof lasts an average of 40 to 60 years. This is considerably longer than a traditional roof, because the vegetation protects the roof covering from sunlight, wind and temperature changes. However, regular maintenance is important to achieve this lifespan.
