Roof Leaks

There is a common expressed concern that flat roofs leak in New Zealand.  If a living roof is designed to meet the German FLL standards it will include a root barrier, which will protect the waterproof layer.  The green roof then protect and act as a barrier to UV and weather damage thereby extending the roof life by two or three times.  It is also noted that some water proofing companies will leak test the waterproof membrane prior to installing the green roof.
