What causes ice dams?
Ice dams are caused by warm air leaking into the attic, which melts roof snow that refreezes at the cold eaves and backs water up under the shingles or shake. The root cause is attic bypass and unbalanced ventilation, not the weather alone.

Why this matters in Minnetonka
This is one of the questions buyers ask us most across Minnetonka and the Lake Minnetonka west metro. The short answer is above; the detail below is calibrated to the homes that actually sell here — lake-adjacent walkouts, 1960s–80s split-levels, and 1995–2008 synthetic-stucco builds.
How a Minnetonka inspection answers it
On every inspection we apply instrument-grade tools — thermal imaging, moisture meters, EIFS probes, and a sewer-scope camera — and deliver a photo-mapped report within 24 hours. If your situation needs a specialist, we tell you plainly. Explore our home inspection, defect library, and learning center.
