Apply for funding for green roofs

Green roofs are not only beautiful, they also store rainwater, relieve the burden on the sewage system, cool the environment, reduce noise and air pollutants, protect the roof and create valuable habitats for plants and insects. Against this background, the senatorial authority supports the greening of roofs with subsidies.

Funding is available for the installation of green roofs of 10 m² or more on new buildings and for retrofitting existing roofs with extensive or intensive greening. All costs incurred in connection with the measure from the upper edge of the roof waterproofing are eligible. Measures to improve the load-bearing capacity of roofs in connection with green roofs are also eligible for funding.

Funding is available for up to 25% of the eligible costs of greening, up to a maximum of EUR 5,000. The maximum funding amount per square meter of greened area is 45 euros.

If the rooting layer is at least 15 cm high or rain retention is at least 70 %, up to 30 % of the eligible costs of a plant are subsidized, up to a maximum of 6,000 euros. In this case, the maximum funding amount per m² of greened area is 50 euros.

If a planting or design that promotes biodiversity is provided with a rootable layer of at least 10 cm (at least one diverse planting with a flowering period over the entire vegetation period, other options: "mounds" with substrate, nesting opportunities for insects, etc.), the funding is increased by EUR 5 per m² of greened area. This bonus amounts to a maximum of 1,500 euros per grant per plot.

If unexpected additional costs arise during the construction phase, a subsequent approval can be applied for in writing. However, the maximum subsidy amount of 5,000 euros may not be exceeded. Personal contributions are not taken into account for the subsidy.
