Yet another roof venting question
By far the most common method of venting trussed-roofs is to couple the soffit air intakes with a series of roof vents situated near the peak. Drive through any subdivision and the houses sprout them like mushrooms – and if they are sized appropriately they seem to work quite well.
One of the injunctions repeated here is that having a combination of gable and ridge vents can be problematic because they can short-circuit the movement of air from the eave to peak. Why would having those two vents near the peak cause problems when a series of roof top vents doesn’t seem to?
