To create ventilation for a flat roof you will need to circulate the air in the attic or plenum. Attic ventilation is important as it can help maintain the health of the building. Removing unwanted heat in the summer and excess moisture in the winter will help the life of the roof. This will also help the functionality and efficiency of the HVAC systems. Here at AVP, we have a vent for any roof pitch in all climate zones.
