ARMA Technical Bulletin: Considerations in Attic Ventilation System Selection

Attics generally fall into one of three configurations. Each attic configuration interacts with and affects the asphalt roofing systems installed over the attic space. This technical bulletin, published by the Asphalt Roofing Manufacturers Association (ARMA), takes a deeper dive into the considerations when evaluating an attic’s ventilation needs. Key takeaways from Considerations in Attic Ventilation System Selection include:

• Attic ventilation helps fight heat, moisture, and ice dams

• To work properly, attic ventilation should be balanced with intake and exhaust airflow

• Do not mix different types of attic exhaust vents on the same roof above a common attic.
