Do Green Roofs leak?
No, a Green Roof will not cause leaks, only poor installation or incorrect specification of the ‘standard’ roofing materials will result in leaks on new builds. When retro fitting a Green Roof on an existing building extreme care must be taken not to damage the existing roofing material. However, as with a new build, the Green Roof itself will not cause leaking if all other materials are fit for purpose.
