Pitched Roof Ventilation is achieved by creating air changes in the attic. Roof ventilation is crucial to attics as it positively affects the home inside and out. Removal of excess heat and moisture will help the life of the roof and the efficiency of the HVAC systems within. Pitched roof ventilation is beneficial in all climate zones and in every season.
Pitched Roof Ventilation should be accomplished when you have equal amounts of air exhaust on the roof with air intake typically under the eaves. Exhaust vents should be placed on the upper portion of the roof, meaning no lower than 2ft from the peak. Air intake must be on the lower end of the roof.
