Who is it for?

This subsidy is for owners of a home or property (such as as business, school, neighbourhood centre or housing corporation) and for homeowners associations (VvE).


You have until 31 December 2021 to apply for the subsidy. Once the subsidy funds have been used up, the measures will stop and you will no longer be able to apply. This will be published on this page.

First check if your roof is suitable for a ‘green roof’. You can discuss this with a certified (roofing) company. Is your roof suitable? Then you can have your green roof constructed. You will only get a subsidy if you have the green roof constructed according to the conditions below. You can apply for a subsidy once the work is finished.

  • The green roof should be constructed in accordance with the building regulations. You need a permit if:

    • a structural adaptation is needed for the green roof
    • the building is listed as a monument or has protected status and the green roof is visible from the street. Check at the city district office whether you need a building permit and whether the building has protected status.
  • The roof surface you will be planting is at least 6 square metres (m2).
  • The green roof must have a minimum storage capacity of 18 litres of water per square metre.
  • The roof slope is not more than 35° (degrees). There are special roofing kits on the market for slanted roofs to prevent the plants from sliding off. You are advised to consult a certified company in order to select the right green roofing kit.
  • The green roof must have at least 1 layer on top of the existing roofing to form a physical barrier in order to prevent root penetration (root barrier membrane).

For the construction of a ‘green roof’ you can get € 25 per square metre of green roof up to a maximum of 50% of the construction costs. The maximum total amount is € 20,000 per application.

    Needed for the application

    Send the following documents with your application:

    • a final invoice (bill) from the supplier or builder who constructed the green roof, or receipts if you constructed your green roof yourself. This invoice must show that:

      • 1 root barrier membrane was constructed on top of the existing roofing layer
      • the water storage capacity of the green roof is at least 18 litres per square metre
    • a photo of the roof without vegetation and a photo of the green roof
    • a declaration by the builder confirming that the roof satisfies the conditions
    • a copy of the most recent bank statement showing that the bank account is in the applicant’s name

      When to construct the roof

      You can construct a green roof almost all year round. You can consult with your supplier to determine the best time for you.

      Combine with subsidy for roof, floor and/or external wall insulation

      In addition to the subsidy for a green roof you can also apply for the subsidy for roof, floor and/or external wall insulation. The combination of roof insulation with a green roof on top makes for a well-insulated home.
