Roof Ventilation
Proper attic ventilation prevents ice dams, extends shingle life, and lowers energy costs — ridge vent, soffit vent, gable vents, and powered options.
Why Ventilation Matters
Prevents Ice Dams
Keeps the roof deck cold so snow doesn't melt and refreeze at the eaves.
Extends Shingle Life
Reduces attic heat that prematurely ages shingles from underneath.
Prevents Moisture Damage
Exhausts humid air before it condenses on framing and sheathing.
Ventilation Types
Ridge Vent
Runs the full length of the roof ridge. Provides continuous exhaust along the highest point of the attic — the most efficient exhaust vent type.
What We Stock
- • Shingle-over ridge vent (low-profile, 4′ sections)
- • Rolled ridge vent (continuous, 20′ rolls)
- • Filter-fabric inserts (external baffle style)
Soffit Vent
Intake vents installed in the soffit/eave area. Partners with ridge vent to create balanced airflow from bottom to top.
What We Stock
- • Continuous soffit strip vent (2″ × 8′)
- • Individual rectangular soffit vents (4″ × 16″, 8″ × 16″)
- • Round soffit plug vents (3″, 4″)
- • Perforated soffit panels (aluminum)
Gable Vents
Vents mounted in the gable end walls. Used as exhaust when ridge vent is not feasible, or as supplemental ventilation.
What We Stock
- • Aluminum gable vents — rectangular (12″ × 18″, 14″ × 24″)
- • Aluminum gable vents — triangular (various pitches)
- • Paintable polymer gable vents
Power Ventilators
Electrically or solar-powered fans for challenging attic configurations where passive ventilation is insufficient.
What We Stock
- • Roof-mount power ventilators (thermostat-controlled)
- • Solar-powered attic fans
- • Gable-mount power fans
Rafter Vents (Foam Baffles)
Foam or plastic channels installed between rafters to maintain a clear airflow path from soffit to ridge — prevents insulation from blocking intake vents.
What We Stock
- • Foam rafter vents — 14½″ × 48″ (standard rafter bay)
- • Foam rafter vents — 22½″ × 48″ (wide rafter bay)
- • Plastic ProVent baffles — 14½″ × 48″
Balanced Ventilation
Building code requires 1 sq ft of net free area (NFA) per 150 sq ft of attic floor — split roughly 50/50 between intake (soffit) and exhaust (ridge). An imbalanced system actually makes ice dams worse.
Our staff can help you calculate how much ventilation your roof needs. Bring in your attic dimensions and we'll spec the right combination.
