Check Attic Ventilation Before Summer Heat

Cost Savings

Checklist Tasks

• Inspect soffit and ridge vents for blockages that reduce attic airflow.
• Use a smoke pencil at intake and exhaust vents to confirm attic air movement.
• Check rafters and roof sheathing for stains or condensation from trapped heat.
• Measure attic temperature on a sunny day; over 20°F indicates poor ventilation.
• Verify attic baffles above insulation at eaves to keep air channels open.
• Look for compressed insulation near attic perimeter that could block airflow.
• Examine gable vents for clogged screens or louvers and clear as needed.
• Test attic fans and confirm they activate below 110°F to prevent heat buildup.
• Check for uneven shingle aging or curling from attic side, indicating heat issues.
• Ensure bathroom and kitchen fans vent outdoors, not into the attic space.
• Look for daylight around vent openings, which can signal missing vent covers.
• Document musty odors or excess dust, indicators of stagnant attic air.
