venting for enclosed rafters


I am adding a living room to our home, so we have hung 2x12 rafters from our second floor wall at a 3.5/12 pitch. They will be enclosed (roof sheating, above and sheet rock below). My question is how to vent this. I can obviously drill holes for air intake at the blocking, but how do I get the the air out since they attach direct to the second floor exterior wall. Do I have to put those ugly vents between each rafter? Is there another system that works?

Well, the short answer is - how long will you own the house? If you don't care if the roof burns out prematurely, then don't vent it....

I've used products from Cor-a-vent a lot, and like them.

Good luck.

Yes they make a shingle to wall vent I highly recommend it and pay particular attention on flashing it because of the shallow pitch and wind blown rain. I usually install them on a built up curb that is fabricate on the job site. BOB http://www.airvent.com/homeowner/pro...tyFilter.shtml

Smart Vent, by DCI Products makes a tapered, Shingle Over Style ventilation product that works very well in this situation.

You can run it continuously along the wall and it will get covered by the shingles and the Roof-To-Wall Apron sheet metal flashing.

Here is the link to the roof To Wall Venting page:
