Green Roofs
Green Roofs
(OP)
I am looking for anyone who has experienced or heard of structural complications caused by green roofs. Talking about design of new structures. Unintended consequences. Gaps in codes. Adverse structural effects in structural maintenance, etc.

RE: Green Roofs
What I recall (it has been almost 20 years since I worked as an owner's rep. with such a plaza) was a plastic drainage tile over a liquid applied membrane with drains, and protected by a concrete topping slab. The soil (I seem to remember like 5') is placed on top of that, along with irrigation and electric, and then topped with vegetation including trees, bushes, and grass. The main structure was a steel braced frame with reinforced concrete foundation walls and composite concrete over metal deck.
