This way, you enjoy a sustainable roof for years to come, with a 10-year warranty on the underlay.

A green roof starts at the bottom

By Smienk Dakwerken

Why do we first examine what lies beneath the greenery before installing sedum? Because a sedum roof is only as good as the roofing underneath. If there is an outdated layer underneath, you are introducing problems.

We check whether the bitumen roofing ensures it is still watertight and root-resistant, and renews these where necessary. On top of this, we lay the structure of drainage, substrate, and sedum. This gives you a green roof that insulates and changes color with the seasons, without any surprises underneath.

The benefits of a sedum roof

The benefits

A sedum roof provides extra insulation, keeps your roof cooler on hot days, and protects the roofing against UV and weather, extending its lifespan. Additionally, it buffers rainwater, relieving the strain on the drainage system, and it is beneficial for bees and butterflies. Moreover, a green roof simply looks beautiful.

Sedum roof install on your flat roof

The construction

We install sedum using sedum cassettes or as a separate structure with drainage and substrate, tailored to the load-bearing capacity of your roof. A sedum roof is suitable for most flat roofs, provided the structure can support the weight. We assess this in advance so that you can be certain your roof is ready.

Subsidy for a green roof

Save with a subsidy

Many municipalities provide subsidies for the installation of a green roof or sedum roof, as it contributes to water retention and cooling. The regulations and amounts vary by municipality and change regularly. We inform you about the possibilities in your municipality so that you do not miss out on any subsidies.

How much does a cost sedum roof?

Clear rates

The costs depend on the surface area, the structure, and whether the sub-base needs to be renewed. After a free inspection, you will know exactly what is possible, what it costs, and which subsidies you can apply for. You will receive a fixed price in writing, with no surprises. The inspection is free and without obligation.

We work with premium brands

For long-lasting results, we work exclusively with proven quality brands, including Monier, Wienerberger, and Bitasco.

        Excellent roofing work and craftsmanship. The collaboration went well; often things don't go according to plan on projects, but we resolved it perfectly. Thanks also for the extra service; we got the unblocking of another gutter included, which saves us some climbing around. I look forward to having them back for my next roofing project.

        Little. Checking once or twice a year and lightly fertilizing is usually sufficient. Sedum is a strong, drought-resistant plant.
        Only if it is still waterproof and root-resistant. If the sublayer is aged, we renew it first; otherwise, you will create problems.
