The local government of Hamme is offering a subsidy for the installation of green roofs, amounting to €15 per square meter.

Green roofs, which are roofs primarily covered with living plants resistant to wind, heat, frost, and drought, are now eligible for a subsidy. Installing a green roof can provide financial compensation.
To qualify, the green roof must include a drainage layer, a substrate layer, and a vegetation layer. The building must be used mainly for private purposes. The applicant must be the owner or tenant (with the owner's consent). Previous subsidies for the same green roof are not permitted. The green roof must be maintained for at least ten years. The maximum subsidized area is 50 m², and terraces or intensive green roofs are excluded.
Applications are submitted online via a form. The college of mayor and aldermen reviews the application. Upon approval, a local government employee will conduct an on-site inspection. After all checks are completed, the subsidy will be disbursed.
The subsidy amount is €15 per square meter. Through this measure, the local government aims to encourage the installation of extensive green roofs, which require little maintenance and often do not need adapted roof structures.
