My Bungalow style home would apear to make soffet (s) vents impossible to install, have 4 roof vents but nothing else, plan on 2 Gabel vents (large) to help feed the roof mounted vents equalize and maintain ambient temps.

My 2 year old shingles on southern exposure are wasted, curled and junk so Im sure ventalation is the issue. Spraying in 20 bags of pink next weekend to get R value up to date.
