I'm in a similar situation as the OP, except for living in Tucson, AZ,
where the big problem is the attics getting extremely hot (160+
degrees) and radiating heat down into the living space. (I've come
to realize peaked roofs make utterly no sense in Arizona).
The consensus seems to be that getting the built-up air out is the key,
with air coming in from as low as possible (i.e. the soffet area),
exhausting it passively at or near the peak of the roof, and
making sure to have enough square feet of area in the inflow and
But there's remarkably little information out there about products,
a) soffet vents, other than cheap 16" x 8/10/12" perforatd metal,
b) ways of getting the inflow of air from the soffits up above
the attic floor and insulation (in an existing house).
I've been to three home centers and two roofing supply specialists,
all in Tucson, and no one has any range of alternatives for (a),
and none has a clue about (b). I was particularly
struck by the fact that the roofing supply guys really had no
idea there was even a problem in getting a clear pathway from
a soffet vent to the airspace up above the insulation. (In my house,
the roof slopes down enough that the sofets are about 3-4 feet
below the attic floor, and so 4-5 feet below the insulation
If anyone has any sources, even mail order, I'd appreciate the tip.
What I'm looking for for soffet vents is a continuous length
of peformated metal, that looks fairly nice, that could span
a 24" wide and 23 foor long area.
