Continuous soffit vent retrofit

S-F · 10-19-11, 01:53 PM

I have a token few measly 1" soffit vents and gable vents and a continuous ridge vent. This isn't good because the lack of lower ventilation will create negative pressure in the attic sucking warm air out of my house! I could put those 4" round vents in pretty easily I guess but a continuous vent will give more ventilation. But how do I install a continuous soffit vent? I'm not really interested in tearing of the gutter, facia and soffit to install a new vented soffit because next spring I'm going to built a new one entirely when I toss 5" of polyiso and a rain screen on. Why can't I just snap 2 lines under there, set the depth of a circular saw so I don't trash the joists or whatever's in there (just like installing a ridge vent) and fit a new continuous vent in? How would I attach it?
