thorough and permanently green upgrade

Sempergreen has different solutions for green roof restoration. We can make use of sedum blankets or plant cuttings and can implement different maintenance strategies. We always start by inspecting your roof and acquiring soil samples for lab testing prior to renovation. This way, any potential underlying problem can be identified and addressed first. After that, we prepare for renovation by removing debris, unwanted plant media and netting in damaged areas. Depending on the roof specs and the desired outcome, we offer different remediation options. All of them with a permanent green result.

Storm water management and green roofs

After the first phase of roof inspection and soil testing, our team of experts will remove debris, unwanted plant media and netting in the areas that are in need of restoration. We will loosen and level the growing media to prep for fresh plant cuttings.

Based on our tailored advice, we will deliver, unload and install the fresh plants, restoring the desired coverage in damaged areas. Sempergreen also takes care of the vertical transportation of the plants.

Sedum blankets

The use of sedum blankets as a green roof renovation solution is a guarantee for a succesful green roof. Sempergreen offers sedum blankets for existing roofs as well as new buildings. Various solutions are possible, from lightweight blankets to water detaining sedum roof coverings for stormwater management.
