My house is a bungalow/ranch style home. Air does not move thru it very well. Even when the AC is working (which it's currently not ) the house is still uncomfortably warm and the AC is working too hard, IMO. There is NO ventilation on the roof to siphon hot air out of the attic. The roof is probably less than 5 years old and still in good shape. The attached garage is miserable in the summer heat as well. I'd like to add some roof vents to purge the hot air out of these areas beneath the roof. What's the best method to go about doing this for someone who has never worked with roofing before? I should add that the soffet is vented (perforated) but there are no vents along the roof.
