I use queen castles for mating queens, last year I used hive roofs on them but this made transporting difficult so I'm in the process of painting up a price of ply 46cm sq to use as a summer roof and adding 4 latches to secure it for transport. So far so good. The ones upgraded have remained rain proof and have been easier to transport.
