The Rizoma system for non-walkable green roofs transitables
Composition of the Rizoma system for non-walkable green roofs (GENERIC CONSTRUCTION DETAIL)
- WEIGHT AT SATURATION: 46 kg/m² + vegetation
- WATER STORAGE: 30 l/m²
- SLOPE: 1-5%. 5-100% with polyurethane membrane waterproofing
- DRAINAGE CAPACITY: In ISO 12958 600 l/min/m
- COMPRESSION STRENGTH: UNE-EN 826:2013 > 10 kPa (at 10% deformation).
- DURABILITY: lifetime warranty
The Rizoma system is a very lightweight and low-thickness vegetal cover that can be placed on flat or sloping surfaces due to the adhesion of the substrate to the lower layers of the system itself.
The Rizoma system uses the latest technology in synthetic substrates, rock wool panels perform the functions of a retaining, draining, and substrate layer with only 4 cm of thickness. On top of them, species of the Sedum genus or grass in sods are placed, obtaining a total substrate thickness of 7 cm. In this case, a buried drip irrigation system is used.

Discover some ideas to combine your non-walkable green roof and improve its use.
Benefits of having a non-walkable green roof
REDUCTION OF THE URBAN HEAT ISLAND EFFECT
The surface temperature of green roofs typically does not exceed 30°C, as opposed to conventional roofs that can reach 70°C.
REDUCTION OF SURFACE RUNOFF
Green roofs store rainwater in the layers with a retention function, reducing the volume of water that needs to be evacuated during precipitation.
IMPROVED THERMAL INSULATION
Green roofs have high thermal inertia thanks to the water in the substrate, and benefit from protection against wind and shading from the vegetation.
IMPROVED ACOUSTIC INSULATION
The vegetative layer (plants + substrate) reduces noise through the absorption of sound waves in the substrate and reflection in the vegetation.
IMPROVED AIR QUALITY
Plants are able to absorb certain volatile toxic elements in the air, converting them into organic matter.
ENABLEMENT OF NEW URBAN GREEN SPACES
Thanks to green roofs, unused spaces on buildings can have a second chance to go green.
INCREASED LIFESPAN OF WATERPROOFING
Green roofs reduce movements due to expansions and contractions, and the substrate protects the membrane from ultraviolet rays.
PROMOTION OF NATIVE SPECIES
Green roofs allow for the use of virtually any plant species, including native ones.
Not only will planted species benefit from this new space, but the fauna is also part of the biodiversity that this nature-based solution promotes.
Discover step by step the layers that a Rizoma non-walkable green roof needs and how it is built.
Frequently Asked Questions
What is the most suitable system for my project or home?
When planning a green roof, in addition to everything explained, we also need to take into account the following points:
- The budget. Depending on the estimated cost, we will opt for one system or another.
- The load that the slab supports. If we have a slab with little resistance, we will look for lightweight solutions.
- Orientation. It is very important when choosing our vegetative cover.
- Inclination. If we exceed certain degrees of inclination, additional drainage and soil support systems must be considered.
- Transport of materials to the roof.
It is important to consider this point to choose systems that are easy to transport in case of difficult access.
At SingularGreen, we will advise you on the best system or design custom solutions for your case.
Can I have a non-accessible green roof without maintenance or irrigation?
Low maintenance green roofs typically use species of Sedum and succulents that do not require any irrigation.
However, they can and often are colonized by invasive species that do not guarantee the initial aesthetic finish, which can be solved by removing these invasive species annually.
What uses can I give to a RIZOMA vegetative roof?
A Rizoma vegetative roof is not compatible with activities that involve constant use (only maintenance).
This is because the inert and hydroponic substrate used in our system is not designed to be walked on as it loses its properties.
But having said that, we invite you to rethink that fifth façade and design combined spaces (walkable and non-walkable).
How many years of useful life does a green roof have?
In Germany, according to a report on construction damage, it was shown that while 80% of flat roofs present the first damages after 5 years of construction, a green roof, with a correct choice of waterproofing and good execution of the joints, has an almost endless useful life.
Can water enter the house with a green roof?
No, if good waterproofing is carried out with the correct materials.
We have to take into account that asphalt sheets, the most commonly used waterproofing products, are susceptible to being perforated by roots and causing moisture problems.
To avoid filtration problems, PVC or EPDM sheets should be installed and the joints made correctly.
The maintenance of non-walkable green roofs is very simple and we explain it briefly in the following video
