Building a house in Zone 6
Building a house in zone 6. Framing nearly complete. Too cold to roof now with asphalt shingles, but rain protection needed. Roofer asked builder if he should extend the "ice shield" which I understand is vapor impermeable, over the whole roof, or cover with ?
Issue relates to the potential trapping of moisture in the sheathing if two impermeable membranes are used.
