Air leaks into attic (soffit vents)

    1. Inspect soffit vents from inside the attic – Use a flashlight to look for daylight or debris coming through vent openings indicating gaps.
    2. Check vent seals – Run your hand along edges to feel for gaps or cracks in the vent housing, screens, or covers.
    3. Seal vents with caulk – Use exterior silicone or acrylic caulk to seal around vent openings and seams. Avoid blocking needed ventilation.
    4. Stuff insulation in large gaps – For larger gaps, stuff fiberglass insulation or steel wool to fill before caulking over.
    5. Install baffles – Position insulation baffles between roof rafters directing airflow from vents into the attic space.
    6. Air seal attic floor penetrations – Seal gaps around wires, ducts, and other openings in the attic floor to prevent air leakage.
    7. Consider professional foam insulation – For widespread gaps that are hard to locate, hiring a pro to spray foam major air leakage areas may be needed.
