Transform your rooftop into a living, breathing ecosystem. A green roof (sedum roof) is one of the smartest investments you can make for your property in IJlst. Through Hovenier FRL, you gain access to certified specialists who design and install green roofs specifically engineered for the Frisian climate.
A green roof (sedum roof) is a layered system covered with vegetation that improves insulation, manages rainwater, and protects the underlying roof structure. Before installation, specialists assess whether your roof is suitable.
A fully saturated green roof typically weighs around 75–80 kg per m². The structure must be able to support this load safely.
Green roofs are most commonly installed on flat roofs, but can also be applied to slightly sloped roofs (up to approximately 35 degrees).
In a region where rainfall levels can be significant, proper drainage is essential to prevent water buildup and long-term damage.
Existing materials such as bitumen or EPDM are checked to ensure they are still in good condition and resistant to root penetration.
From lightweight sedum roofs to intensive green roofs with larger plants and shrubs. The right type depends on your roof structure and goals.
Many municipalities offer subsidies for green roofs. A specialist can advise you on current schemes, permits, and eligibility.
