Expert Verdict — Reviewed by the SuperArbor Pro Desk

Choose slant-back louvers on roofs with limited ridge line or when swapping out older box vents during a re-roof. Keep the ventilation balanced: exhaust at or near the ridge must never exceed intake at the soffit, so plan intake venting at the same time. At 60 sq. in. NFA each, these vents reduce the number of penetrations versus 50 sq. in. units. Follow the manufacturer's installation instructions and local building codes for placement and fastening.

Always consult local building codes for specific ventilation requirements and follow safe roof work practices; exhaust ventilation must never exceed intake ventilation.
