Expert Verdict — Reviewed by the SuperArbor Pro Desk
Static louver vents like the 750-S are a proven choice for pitched roofs where the vent installs below the ridge line. Balance the exhaust NFVA against adequate soffit intake so the attic actually moves air. Install per Lomanco's instructions with proper flashing and sealant at the flange to prevent leaks.
Cut roof openings carefully and seal the flange properly; use fall protection when working on a roof.
Order the Lomanco Model 750-S slant back roof louver in brown for dependable attic ventilation.
