Update: the New Roof...

Here's a snapshot of the fascia and soffits going up on our house.  The drip edge that sticks out a little isn't quite finished yet – there are gutters going underneath that before it's all done.  I don't have any “before” photos, but trust me – this is far more attractive than the old fascia-and-rafters.

At left is a close-up of one of the grills in the soffits.  These are spaced quite closely together (about three feet), much closer together than the now-hidden vents under the eaves.  They're made by a combination of punching and stamping, exposing small slots along side each punched area – too small for embers to get in, and very strong.  Because there are so many of these grills, we're expecting that there will be no significant restriction in the airflow.  When our roof is hot, the warm air in the attic will rise and flow out of the dormer vents (yet to be installed), and relatively cool air will flow in through these grills (and the pre-existing under-the-eaves vents).  This should produce much more airflow than our old roof, and will hopefully keep the temperatures down below the typical 170°F we've seen in the attic during the summer...
