green roofs

**C* T* E* <c*@gardenvista.com>**

Does anyone have any information on the success rate of green roofs on 
commercial buildings in this country?  Through a friend who has just 
completed a green room on his garden shed, I heard of someone in a condo 
in DC.  The association wants to redo the roof (which is in none too 
good condition) as a green roof. The person I heard about was voting 
"no" because he says the large commercial applications have a "high 
failure rate." That is, they leak, and plants die out and have to be 
constantly replaced at a great expense. My assumption is that they 
either didn't build them properly, or chose the wrong plants?   Any 
thoughts or information?  I know a huge percent of commercial builidings 
in Germany have green roofs, but perhaps we are still far behind in this 
country...
    Thanks,
