Venting a warm closed attic

Putter76 | Posted in General Questions on

We live in southwest Ohio. We own a 100+ year old house with a one story addition. The addition has a truss roof with slight pitch with attic that is 24 inches at highest point. The insulation is 2lb. foam on underside of roof deck. There is no ventilation to the attic space. 

During a period of extremely cold temperature we had a small area of condensation on ceiling drywall. We discovered an area of spray foam that did not have adequate depth and had additional foam installed. 

My question is should this space be vented into the  living space?
