Hi.=20 I've a cape cod house (in New York) with a shed dormer on the upper floor, = very similar to the diagram here =20

I know that the roof's steeper-pitched areas need to be vented from the sof= fit on the 1st floor, through to the ridge vent. But... my question is what should I do for insulation in the remaining roof= below the dormer, identified as the "apron" on this diagram (highlighted w= ith red arrows)? I've exposed from the inside and can see there is only fib= erglass bat insulation pushed up against the roof deck and even into the so= ffit. There are no soffit vents in this section, yet it certainly does leak= air (soffit and facia are 1"x6" nailed together and you can see daylight b= etween the cracks). Should I air seal the soffit and fascia in this area, i= solate it from the vented portion of the roof, and hope for the best? It's = on the north side of the house, so I'm not really worried about heat gain.
All comments greatly appreciated!!=20 thanks=20 Theodore.
