looks like your on the right track. A general rule of thumb you can't have too much venting.....as long as soffits (intakes) equal or exceed roof (exhaust) vents.

You are under IBC; http://www.cmdgroup.com/building-codes/michigan/


3' vertical distance between vents- no vapor retarder; http://publicecodes.cyberregs.com/ic..._12_par004.htm

Problem with those small holes/punches is they tend to clog with dirt from moisture going through the itsy hole, be sure to clean them regularly- with a brush- not the water hose. http://cthandiman.com/services/vinyl...ts-and-fascia/

17,000 dryer fires a year, when did you last clean the inside of the dryer near motor or the exhaust ducting?

coincidentally a similar issue turned me off to ridge vents. Eventually the fiberglass or foam filters get as dirty as your furnace filter yet there is no way to ever change them.
