Pitched Roof Venting

Roof ventilation in a cold climate vents moisture and ensures a cold roof temperature to avoid ice dams.

Pitched roof venting.

It alleviates moisture in the winter and heat in the summer to extend roof membrane life. Vent roofs with steeples towers or cupolas can be found in different buildings from barns to cathedrals. Pitched roof ventilation is beneficial in all climate zones and in every season. The enclosed void of a warm pitched roof may not require to be ventilated but this is usually subject to the requirement to install a fully sealed air and vapour control layer avcl in conjunction with an air open roof covering.
