How you qualify for a green roof subsidy:
Do you want to apply for a green roof subsidy? Many municipalities provide subsidies to contribute to climate adaptation. This includes: greening the city, water storage, and saving energy. Installing a green roof can feel like a significant investment, but when you receive compensation for this, it becomes a lot more attractive. Also, the green roof also provides many advantages.
What you should pay attention to:
When applying for a green roof subsidy, the following points are regularly asked;
- The water absorption per square meter. At Marvy Green, we supply the green roofs where the sedum roll system contains a substrate mat of 40mm. This ensures a water absorption of 34 liters per square meter. This also offers a better soil for the plants. The saturated weight then amounts to 59 kilograms per square meter.
- Amount of (sedum) plants in the vegetation blanket. Our vegetation blankets contain 8+ different types.
- The size of the roof and the costs for advice, construction, and the green roof materials as such.
Always check whether you need to apply for the green roof subsidy in advance. In many cases, this can be submitted up to 3 months after placing (or requesting a quotation). Are you unsure about a number of things? You can request a quote from us without obligation
, taking into account the requirements set by the body where the application is submitted.
Where to go to:
Are you going for a green roof subsidy to the local water board or to your municipality? This depends on the place of residence and therefore the subsidies can also differ. In addition, they often refer to the water board as an incentive contribution instead of a subsidy. In most cases, you can quickly get 20% of the costs reimbursed. The overview below shows the procedures of the various municipalities in the Netherlands.

The financial benefits of a green roof:
Indoor temperature drops in the summer.
This of course differs per situation, but on a hot day, the temperature can be 4 degrees Celsius lower than with a normal roof. This is mainly due to the reflection of the sun’s rays from the vegetation.
Electricity consumption decreases in the summer.
If you keep the house cool in the summer by means of an air conditioning unit, you can save about 3 to 7% in energy costs. Less gas consumption in winter. Research has shown that homes from the year 1988 to 2012 have an average of 2% fewer gas costs in winter. This is partly due to the substrate layer that traps air between the vegetation. This provides extra insulation.
Outside temperature drops.
A green roof retains less heat than a black bitumen roof. The evaporation of the retained rainwater also influences the ambient temperature.
Solar panels perform better.
A solar panel performs best at a temperature of 25 degrees Celsius and on a bitumen roof, it is quickly a lot warmer in the summer. On average, a solar panel on a green roof delivers about 6% more energy.
For which other initiatives can you receive funding?
When you apply for a subsidy through the water board or your municipality, you can often also apply for a subsidy for other forms of water collection. Consider, for example, placing a rain barrel.
