At a recent log and timber frame home show a timber frame company rep was giving a talk about panels and installation.
He said the panel industry is moving away from installing sheet rock and or paneling on the panels first then installing the insulated panel to the frame for the damage factor. Also, once the panel with sheet rock is attached to the frame it needs to be waterproof to prevent rain from damaging the sheet rock.
Which ever method you choose from the before mentioned procedures, be sure to be ready to protect your entire roof from rain until it's shingled and weather tight.
Good luck with your project.
