Green roofs, sedum roofs, living roofs – so many names for the same thing. Here on our questions & answers page, you can find answers to the most common questions about our sedum roofs.
If you can’t find an answer to your question, then contact us here for more information.
Sedum roofs are roofs covered with sedum plants, a type of stonecrop, which are particularly suitable for the harsh conditions roofs are often exposed to. These plants are known for their ability to thrive in varied weather conditions, including strong sunlight, strong wind and extreme temperatures. Therefore, they are also excellent for the Danish climate, which is known to vary a great deal throughout the year, with high and low temperatures.
With roof slopes of over 15 degrees, support profiles must be used to keep the sedum trays in place.
Please contact Nature Impact for guidance on support profiles.
We don’t sell sedum roofs to private individuals, but you can contact your local carpenter, roofer or timber supplier. They are sure to assist you further with your request.
The sedum plants are placed in relatively shallow trays with a growth medium, and need to be fertilised twice a year as recommended.
You can read what type of fertiliser you should use for your sedum roof in our operation and maintenance plan. You can buy fertiliser for sedum from Nature Impact. There is also the option of a service agreement, whereby we regularly fertilise and tend your sedum roof.
Once we have delivered the sedum trays, the green roof should be laid within 48 hours to avoid drying out and damage to the growth medium.
The weight is always measured in the roof’s saturated state, i.e. the heaviest weight. Nature Impact’s 60 mm sedum trays weigh 50 kg per m2.
The weight of the 80 mm sedum trays is 65 kg per m2.
It’s always a good idea to have the bearing capacity of the rafters checked before laying a green roof, so you are sure the construction can bear the weight of the sedum roof.
It’s difficult to give a clear answer to how much a sedum roof costs, as the price depends on several factors. The size of the project and the mounting costs in particular are decisive for the overall price. Contact us to discuss what a sedum roof from Nature Impact costs.
