Venting attic after insulation
#1

I recently had a new roof put on including plywood. I insulated the entire attic with a thick insulation (R-30). I then realized that I should have vented from the sofit to the ridge vent. Is there anyway to add venting after the inlsulation is already in? I also plan to drywall over the insulation because I am adding a loft office and an extra bedroom up there.
