I was told by contractors that you basically want the same temp under the
roof that you have above the roof to get the max life out of a roof.
Personally, I'd unblock the vents.

I noticed recently (on a house we've owned 2 years) that the blown in
insulation in the attic was blown right into the soffit gaps. I am
interested in improving soffit venting as i have a "wee bit" of faint frost
on the main header in the winter and am hoping the AC won't work as hard in
the summer.

So I got up there today with a scoop I made with sheet metal and a broom
handle, hoping to pull out the plugged up gaps. It turns out that the
batt insulation (with the paper on the back) was installed in such a way
that it is stuffed into the gaps as well!!!!!!!! Its obvious this has
been the case for the 20 years of this house's life.

I'm perplexed now....I've got 3 of the regular square type vents near the
roofs peak, and a pair of about 24x24 gable vents (one on either side).
I'm thinking about having two of the three top vents changed to turbine
style, but am told that with plugged eaves, the turbines will make a
negative pressure and draw household air into the attic.

What do I do? Is there sense in taking down some of the soffit/fascia and
seeing if I can rectify from the outside? It doesn't look possible.....
considering it has been this way for a LONG time and there doesn't appear
to be any sort of systemic damage from it, I'm almost tempted to just
install the turbines and say screw it.

any ideas?
