The Short Answer

An attic inspection looks at insulation depth, ventilation, and signs of roof leaks or pests. Good insulation and airflow help control energy costs and prevent moisture damage.

What the attic does

The attic buffers the living space from outdoor temperatures. Insulation slows heat flow, and vents let moisture and hot air escape.

Quick Poll

Have you ever dealt with a attic insulation or ventilation problem?

What to look for

Thin or uneven insulation, compressed areas, bathroom fans venting into the attic instead of outside, blocked soffit vents, dark stains on the roof deck, and signs of rodents. Ice dams in winter often point to insulation or ventilation problems.

Why it matters

Adding insulation is often one of the more cost-effective upgrades, and utility rebates may be available. Ask the inspector for the approximate depth and type, and request a specialist for any suspect materials.
