Can Monica's roof be safely insulated when it has so many penetrations?

• The PV mounting system holes are unlikely to leak.

• The roof can be safely insulated as long as a ventilation channel is provided.

• Go ahead and install closed-cell spray polyurethane foam against the roof sheathing.

• Go ahead and install open-cell spray polyurethane foam against the roof sheathing.

• I would be too nervous about potential leaks to insulate this roof.
