Wind up-lift and wind resistance of Green Roofs

Many studies have been made and published related to wind resistance of Green Roofs, but in reality there is still a lack of consensus in the international green roofing / building industry on what kind of testing and certification would be most appropriate and representative of real wind effects on vegetated roofs.

Physics behind wind-suction
If we first look at the facts, we don’t often hear of green roofs having been blown-off during storms. Such an event might happen with pavers, waterproofing and similar, but this is not the case with green roofs.
