How can we purpose the rooftops of our cities for a sustainable future?
Groofer transforms your grey roof into a greenroof onto which other sustainable solutions can easily be installed. This allows you to purpose your roof to meet your requirements and the heat and energy-use of your building. It is possible to add elements at later date, preparing your roof for sustainable additions to your building in the future. The size of Groofer is scalable, making it suitable for all roofsizes.
The lightweight and modulair system can be installed in one day on almost all flat roofs, quickly and at low-cost.
Groofer turns unused rooftops into multipurpose rooftops that decrease energy demand, provide renewable energy, assists biodiversity and buffer rainwater, to make for a greener future!

Using the widely available number of grey roofs of our cities is key for a better and sustainable world. A solution like Groofer makes this possible for Amsterdam.

Solar roofs are an important sustainability strategy, and so are living roofs; we need more of both. This system could help revolutionize the industry by letting property owners install both inexpensively and flexibly.”
Dr. Roland Ortt
Professor Urban Innovation Management at Bold Cities Erasmus University Rotterdam
Paviljoen III is an enthusiastic organisation on an important mission: to transform every grey roof to a sustainable multi-purpose roof.
One installation-day van Groofer
Let's go up!
Groofer is installed within 1 day. All components are easily delivered to the roof using a ladder lift.
Installation
Beforehand we determine together with you the components of your Groofer. Do you want to insulate, generate sustainable energy of heat, help biodiversity or store water?
And done!
The only thing left to do is to enjoy all the advantages of your sustainable greenroof.
What do greenroofs do for our cities?
The cooling effect of a greenroof has a positive effect on the efficiency of your solar panels. The efficiency increase is 6% on average, but can reach 20% on hot days.**
Increase solar efficiency
During the summer your roofsurface van reach temperatures of up to 85 degrees Celcius. A greenroof reduces the heat flow on your rooft with 75%!* A greenroof reduces the temperature in- and outside your building.
Passive cooling
Greenroofs provide a place of shelter for insects, bees and birds. They also work as steppingstones, connecting larger green areas of cities and allowing animals to travel.
Help biodiversity
We are experiencing more frequent and heavier rainfall. This leads to flooding and waterdamages in a city environment. Greenroofs store and buffer rainwater, to help fight this problem.
Store rainwater
During hot summer days, our cities can measure up to 5 degrees Celsius warmer tah surrounding rural areas. This phenomena is called the Heat-Island-Effect. The cooling properties of a greenroof help make our cities more comfortable during summer.
Decrease heat-stress
A greenroof contributes to the quality of life in our cities. Research shows that a green environment has a positive effect on our health. On top of that, increases a greenroof the value of your building.
Aesthetic value
A grey roof reflects sound. This leads to noice nuisance, especially in a city landscape. A greenroof absorpts sound. Ideal when combined with a heatpump.
Noise absorption
A greenroof protects your roof surface from the heat and UV-radiation of the sun. A greenroof can double the lifespand of your roof, and in some cases even triple! You will earn your green roof back within 8 to 21 years.***

Vangen van fijnstof en CO2
Planten vangen fijnstof op, en slaan CO2 op tijdens hun groei.
Do you want to see for yourself?
You can see our system on the office building of The Green Village in Delft. Come see how the PavilionRoof tranforms a grey roof into a green/solar roof.
Or is Amsterdam more convenient?
Since Octobre 2023, you can also find a Groofer on the Innovation Pavilion of the Municipality of Amsterdam. Come see the green biodiverse solar roof with the best view in Amsterdam.
