When it is 105°F or 110°F outside, many homeowners assume their attic is about the same temperature. It can be much hotter.
During extreme summer weather, attic temperatures can approach 150°F. Your roof absorbs direct sunlight for hours and transfers that heat into the enclosed attic below.
Without enough airflow, hot air builds faster than it can escape. This creates what we call a heat trap.
Why Is the Attic Hotter Than Outside?
Roofing materials absorb solar heat throughout the day. That heat moves into the attic, where it continues accumulating. Existing roof vents provide a path for hot air to escape, but natural airflow depends on wind, outdoor conditions, vent placement, and available intake air.
During extreme heat, passive ventilation may not move air quickly enough to keep up.
Does Insulation Fix the Problem?
Insulation and ventilation do different jobs. Insulation slows the movement of heat into the living space. Ventilation helps remove hot air from the attic.
Insulation is important, but it does not eliminate the heat collecting above it. Many homes can benefit from both proper insulation and effective ventilation.
How Powered Ventilation Helps
A powered attic fan actively moves trapped hot air through the home’s existing vents. The CMG AF-14 is designed specifically for attic ventilation, helping reduce the extreme heat collecting above the home.
Your AC cannot stop your roof from absorbing heat, but ventilation can help remove that heat before it continues building.
