When attic ventilation gets the attention of the residential roofing contractor, it’s most often the exhaust vents in the spotlight.
This is understandable because the goal of the attic exhaust vents is to get any heat and moisture buildup out of the attic (that is, “exhaust”). That’s exactly what ridge vents, wind turbines, gable louvers, box vents/roof louvers and power fans — the five categories of exhaust vents on the market — are designed to do. That’s why they are an obvious point of focus by the contractor.
