Ice dams & attic ventilation

How poor attic ventilation and insulation create the ice dams that damage Minnesota roofs every winter. In the northwest Twin Cities metro, this is among the issues we document most, and it shows up across a wide range of home ages and neighborhoods.

Why it happens here

Minnesota's freeze-thaw cycles, soil conditions, and the era a home was built in all drive this defect. How poor attic ventilation and insulation create the ice dams that damage Minnesota roofs every winter. Local factors — clay soils in older suburbs, sand plains in Anoka County, and riverfront grading — change how severe it gets from one city to the next.

What we look for

During a 110-point inspection we document the condition with photos, note the likely cause, and explain whether it is a safety issue, a near-term repair, or routine maintenance. We never inflate findings; the goal is an accurate, prioritized picture you can act on.

What it means for buyers

Most findings of this kind are manageable once you understand the scope. The report gives you the leverage to negotiate, plan repairs, or simply budget — instead of being surprised after closing.
