If it has insulation draped from top to top of the Z purlins, you can measure from the underside of the NOMINAL DEPTH OF INSULATION and ignore where it goes back up to the top of the Z. Likely there's 8" or 10' insulation and treated like a smooth ceiling from which to measure from below its NOMINAL location.
