Attic Inspection Checklist

The attic is where problems hide—moisture, heat, pests, wiring, and structural damage. Most homeowners never look up there until something expensive shows up downstairs. This checklist walks you through exactly what to check.

1. Moisture and Leak Detection

[ ] Look for water stains on rafters or sheathing
[ ] Check for damp insulation or compressed spots
[ ] Inspect around chimneys, vents, and skylights for leaks
[ ] Look for mold or musty smells
[ ] Check roof nails for rust or frost buildup (winter sign of poor ventilation)

2. Insulation Levels and Placement

[ ] Measure insulation depth—look for uneven coverage
[ ] Ensure no insulation is blocking roof vents
[ ] Check for gaps around edges, wiring, and framing
[ ] Add insulation if you see exposed joists

3. Ventilation and Heat Control

[ ] Confirm soffit vents are open and not painted or clogged
[ ] Check ridge or gable vents for airflow
[ ] Inspect attic fans for operation (if installed)
[ ] Look for signs of heat buildup like warped wood or melted insulation backing

4. Structural Integrity

[ ] Check rafters for cracks or bowing
[ ] Ensure truss plates aren’t rusting or separating
[ ] Inspect for sagging roof sheathing
[ ] Verify no large gaps in roof decking

5. Electrical and Fire Safety

[ ] Look for loose or exposed wiring
[ ] Check junction boxes for proper covers
[ ] Ensure no wiring is buried under insulation
[ ] Keep flammable storage away from recessed lighting cans
[ ] Inspect HVAC ducts for leaks or disconnected sections

6. Pest and Wildlife Signs

[ ] Look for droppings, nests, or chewed insulation
[ ] Inspect around eaves for entry holes
[ ] Check for scratching noises or trails in insulation

7. Storage and Safety

[ ] Keep walkways clear to avoid stepping through ceiling drywall
[ ] Avoid storing heavy items on unsupported joists
[ ] Check plywood flooring (if any) for rot or sagging
[ ] Ensure attic access ladder is secure and safe

A quick attic inspection prevents expensive water damage, mold growth, and overheating. Handle this list once or twice a year and you’ll stay ahead of almost every attic problem homeowners normally miss.
