I’m pretty sure our one year old roof will cope, 150mm PIR on 200x75 joists. It’s the fibreglass on 12mm OSB & firings I’m slightly worried about. That said I can walk on it fine so I can’t see a distributed load like that being a problem.

Out of curiosity how come? More rigid and at risk of cracking than another form of construction?

Surprisingly, there's was virtually new too.
The OSB should be fine though - my garden office has 12mm OSB (off 400mm centers on 2 x 8) and is supporting a supposed 80+kg wet weight of sedum.

Then they took it down, because their ceiling was bowing.
For one brief moment, it looked great.
