Ridge vents are an effective way to achieve proper attic ventilation and are becoming a popular option for metal roofs. Optimal air movement not only promotes temperature regulation and energy efficiency but also reduces the risk of moisture related issues like condensation build up.

Ridge vents are installed at the ridgeline of the roof. For a finished attic venting is a little more complicated but it s still essential. Prior to installing the ridge vent a 1 inch wide strip of roof decking is cut out along both sides of the ridgeline to allow for air movement through the vent. They run continuously along the entire length of the roof so hot moist air is continuously released from the attic space across the entire ridge.

Airflow enters through soffit vents and flows upward through each rafter space until it reaches the roof peak.
