Long roofing sheets
(OP)
Sounds unnecessary to me, but there it is.

Had an issue a few years back in a church...every Sunday morning during the service, they would hear popping that started on one side of the roof and progressed to the other. Almost the same time each Sunday and loud enough to disrupt the service. Didn't take long to figure that one out.

roof sheeting diaphragms are not common in Australia. We fix through the crest ect....
I am playing cricket with the plumber that installed the roof sheeting on sunday (if it isn't raining), thus I will find out the real storey.

RE is correct. No diaphragm action. The roof plane would have trusses in the form of diagonal bracing to distribute the forces to the vertical bracing elements. Or portals in each direction.
Ron,
Rolling in the field is the way it's 'normally' done here as well. Seems space limitations and security concerns on site didn't allow that. Normal practice here with a concealed fastener roof is to provide expansion steps about every 20 metres or less in the roofing, with double purlins at those joints. This silly architect apparently thinks that double purlins are ugly, and the roofing supplier is encouraging this thinking.
RE,
Playing cricket with plumbers is dangerous, especially if they want to play on the roof.
