Insulation and attic ventilation are listed together in the ASHI Standards of Practice. Although there is a hot-roof theory, which recommends sealing an attic airtight, overwhelmingly home inspectors satisfy the ventilation requirement of the Standards by inspecting, evaluating and reporting on the basic methods of ventilating attics. In order to do so, they become familiar with soffit and roof vents and how to calculate attic-venting requirements. |
