Expert Verdict — Reviewed by the SuperArbor Pro Desk
For balanced attic ventilation, pair each 730 exhaust vent with proportionate intake at the soffits so air actually moves through the attic. Keep vents below the ridge line and space them evenly across the roof for uniform airflow. Pick Black or Brown to blend with dark shingles, Mill for lighter roofs, and galvanized steel variants where a heavier gauge is preferred.
Work on roofs only with proper fall protection and ladder safety; keep louver openings clear of debris after installation.
Add Lomanco 730 slant back aluminum static vents to your roof for dependable 30 sq. in. NFA exhaust.
