Design, planning and preparing for installing a green roof
Before you can start installing you green garage roof, you must ensure that your garage or carport roof meets the prerequisites for a green roof. However, with a little manual dexterity and skill, you can quickly install a green garage roof yourself.
The most important prerequisite for a fitting a green garage roof covering is the static engineering parameters of the garage. If you want to retrofit a green roof at a later date, it is essential that you check the static engineering parameters of your garage. The garage roof must be able to bear an additional weight per unit area of approx. 120kg/m². If this load-bearing capacity is not guaranteed, you cannot install a green roof on your garage. If you are not sure whether your roof is able to bear the additional loads, make sure you have it assessed by a professional.
A certain inclination must be provided even for a flat roof. The garage roof should have a minimum fall of 2% (approx. 1° roof pitch). However, do not exceed a roof pitch of max. 7°, as such a build-up would not be possible without additional anti-slip, shear protection measures.
Of course, it is also important to make sure that the water run-off and seal of the flat roof has been produced properly. Is your roof watertight? Then installation of your green roof can begin.
Important: Safety first: During the entire installation process, constantly ensure that you stay a sufficient distance away from the roof edge and secure yourself against falling using appropriate protective measures (e.g. scaffolding, safety harnesses, handrails).
