Experience at University of NSW was that everything is more difficult when the glasshouses are on the roof. You have to watch out for:
health risk to people underneath the glasshouse from fumigation
high winds that rip off louvres
difficulty in getting at the outside of the roof once it is built
birds that pick the mastic out of joints between panes of glass
nearby cooling towers for the air conditioning system that get infested with Legionella and threaten the health of workers in the glass house.
