Aluminum Soffit Panels: Ventilated Protection for Building Undersides

An aluminum soffit panel gleams in the sunlight, its smooth surface reflecting the surrounding environment

Soffits are where buildings are most vulnerable.

Rain, humidity, pests, and temperature extremes all attack the underside of roof eaves. Wood rots. Vinyl warps. Steel rusts. And when the soffit fails, the damage spreads — to fascia, to rafters, to insulation, to everything above the ceiling.

Aluminum soffit panels solve this. They ventilate, protect, and finish the underside of eaves in a single product that lasts decades without maintenance.

Here is what they deliver and how to specify them.

Aluminum is the only soffit material that handles all threats without compromise.


Soffit Panel Types

Vented Panels

Small perforations allow continuous airflow through the soffit, preventing moisture buildup and regulating attic temperature.

  • Ventilation: 6-10 sq.in. per linear foot
  • Applications: Residential eaves, commercial overhangs
  • Benefit: Reduces attic temperature by up to 20°F, lowering HVAC costs

Solid Panels

Clean, unbroken surface for areas where ventilation is not required.

  • Appearance: Smooth, flat, modern
  • Applications: Entry canopies, decorative overhangs, facade soffits
  • Benefit: Maximum visual continuity

Perforated Panels

Custom perforation patterns that balance ventilation with aesthetics.

  • Patterns: Standard round holes, slots, custom designs
  • Applications: Brand environments, architectural feature soffits
  • Benefit: Ventilation + visual interest in one panel
