Expert Verdict — Reviewed by the SuperArbor Pro Desk

TopShield rectangle gable vents are a workhorse choice for balanced attic ventilation and a clean finished look on any siding type. Upsize to the 20 in. x 30 in. vent when attic airflow calculations call for more net free area. Order the Paintable colorway for custom schemes, and let the snap-on trim ring save time on less-than-perfect cuts.

Cut the gable rough opening carefully to avoid hidden wiring or structural framing, and use fall protection when working at gable height.


Choose the Mid-America TopShield Rectangle Gable Vent in 23 colors and 3 sizes for ventilation that looks as good as it performs.
