yes i agree....much better in every way except plants do destroy buildings! i seem to remember somethign on Discovery Canada talking about a Ford Factory refitting for a "green" veiw....they has some fancy ass roof technology to avoid this very problem (roots)...that was years ago, i cant remember what exactly it was.
i would think this is only good for conrete buildings as wood ones run high risk of fungus, insects and rot! even concrete run risks of roots damaging them, but far less risk than other materials!
The Empress hotel in Victoria BC Canada has ivy growing all over it and has so for many many years! thats expensive 100 year rock buildings for ya!!!
