I've read posts on here referring to strapping or stripping the roof with 1x3 or 1x4 wood strips over existing shingles and underlayment and then roofing over that. I have read to strap verically and then horizontally over that for ventilation. Now here's my questions concerning all of that. If you strap horizontally I assume you might have to install a new fascia to cover the edge strap or would drip edge be enough? If you strap vert. and then horiz. for ventilation wouldn't that vent area be covered by your gutter? Wouldn't you end up with birds or insects getting in your ventilation area? With painted ribbed roofing what would keep insects and such from getting under your roofing at the edge where the ribs leave spaces?

You use one of the vented mesh materials to close the gap that are fine enough to stop insects but allow the air through.

OK, but how about the height from 2 layers of strapping? You would have to move the gutter up and that would cover any ventilation.

The gutter height depends on the type of roof material, profile, roof slope and rafter length. The outside of the gutter height is always below the plane of the roof so it will not impeed the ventilation.
