You might check with the Biology Dept at George Washington University in
DC. They had one on the roof in 1982 and might still.
Ours is not on a roof, but it is a second floor GH over the animal care
facility which is on the first floor. Both were built as an addition to the
science building 20 years ago and while the GH was not built on an existing
roof, it is where the roof would be if the GH were not there over the animal
facility. [Does that make sense? ]
We have had leakage problems at times in places into the animal rooms below
due to design and structural problems [the architects were idiot
know-it-alls who ignored our requests, based on other schools' GH
experiences, and now we live with the problems; I mean putting five floor
drains where we didn't want them and making them the highest places in the
GH created predictable and frustrating pooling of water virtually everywhere
until we had the floor paths raised. The water still stands in places but
at least we don't slosh through it anymore!] Water has leaked down plumbing
which extends between the two floors. Silicone sealant took care of that
till the next gap appears. Make sure the architects or whomever has done
this thing before and knows how to avoid or at least minimize inevitable
problems! Ours was the first, and hopefully last, time the architects had
done such a facility.
