Moisture-Managed Roof
Roof assemblies using spray foam or rigid-foam insulation should be constructed to dry in at least one direction to prevent seasonal moisture accumulation from rotting the sheathing.

Why Do You Have To Separate Grounds and Neutrals?
One of these wires is meant to complete a circuit and the other is there just for safety. Different wires, different jobs. Beginning with the 2008 National Electrical Code, residential subpanels are required to be wired with a four-wire feed (two hots, a neutral, and a ground), and the grounds and neutrals must be isolated from one another. Here, they connect to different bars in the subpanel.
