The vegetation of extensive green roofs usually doesn‘t pose a danger to the building structure, but carried by the wind, various plants can appear on the roof, that have aggressive roots and even ones with rhizomes, that are able to damage traditional water proofing, therefore the root-protection of every roof with vegetation has to be ensured.
