Vented attics have long been a critical part of residential structures. With the complexity of roof designs and increased energy code requirements, attic ventilation design is worth revisiting. This webinar will examine baseline attic ventilation code requirements, highlight common trouble spots in new construction, and provide best practice recommendations for new homes.

Learning Objectives

  1. Examine baseline code requirements for attic ventilation in the 2018 International Residential Code.
  2. Discuss the key functions of attic ventilation including ice dam prevention, moisture relief, and others to maximize the durability of the roof assembly and reduce the risk of mold growth.
  3. Review common pitfalls when applying attic ventilation principles to common roof designs in new homes, including the challenges associated with complex roof designs.
  4. Understand best practices for providing a robust and durable roof assembly using modern construction materials and assemblies.
