In the pic attached, standing seam panels are apparently installed over purlins, instead of directly atop the papered or membraned roof.
This roof is done with SIP panels, and the top surface of the SIP is 7/16" OSB.
So, what happens usually?
I'll not use the SIP, but will likely use OSB, maybe Huber's Zip-wall coated product.
Rafters will be 24" on center. What is the preferred thickness of the sheathing for the deck? Must the roof be strapped with purlins, as shown in the pic? If so, what is the makeup of the purlins?
Wood? Rollformed steel hat sections?
