2026 U.S. roof ventilation planning ranges scale with vent count / ridge length proxy and type (box, ridge, powered). Balanced intake/exhaust and roof pitch affect both code compliance and labor. Adding or upgrading attic intake and exhaust ventilation to reduce heat and moisture. Ridge, soffit, and powered fans must be balanced as a system.
