fibreglass roof finish around soffit. is this right?

[Thegroundhog]

The parapet roof is finished in fibreglass and the builder has provided a lip all the way around the extension as a finish.

However some of the OSB board used for the roof is still exposed under the lip of the fibreglasss, see enclosed image which shows this. is this normal? The OSB board is obviously part of the internal roof so if it was exposed to the elements over time, it would i believe rot.
Or am I worrying about nothing? Or should this be covered with something?

Thanks for any clarifications

Hopefully you will post more wider views and exact detail of the OSB complaint - the right way up.

I think I see a wall

There should be a drip formed so the water should not track back onto the osb.
Does the osb get wet?

All the OSB should be covered; that's the essential idea about using fibreglass to seal it.
