Current situation: Finished walk-up attic with fibreboard in varying
states of disrepair over fiberglass/wool? batts(probably done in the
60's) in the walls and roof. Attic has no soffit vents only two gable
vents at either end. Clapboard is nailed directly to wall studs. HVAC
unit located in attic that supplies second floor and attic (currently
kept closed). No return in attic. Roof is approx 5 years old. Want
to rip the whole thing out and start over. How should I proceed? Need
some ideas before talking to the contractor since most aren't used to
the peculiarities of old house.
