Why attic ventilation and insulation make or break a Minnesota roof, and what we check. This guide is written for Minnesota homes by Closer Look Inspectors.
Why the attic matters most in winter
A Minnesota roof's worst enemy is a warm, poorly ventilated attic. Heat loss melts roof snow and feeds ice dams; trapped moisture frosts the sheathing and drips as it thaws. Insulation depth and balanced intake-and-exhaust ventilation are what keep the roof healthy.
What we check
Insulation depth and coverage, air-sealing at penetrations, attic frost and moisture staining, bath and kitchen fan termination, and whether soffit intake and ridge or roof exhaust are both present and unblocked.
The payoff
Getting the attic right reduces ice dams, extends roof life, lowers heating bills, and prevents the hidden moisture damage that shows up years later as rotted sheathing.

- Check insulation depth and air-sealing
- Balanced intake and exhaust ventilation
- Right attic equals longer roof life
