25 Roof Leak Warning Signs (With Photos) — When to Call a Roofer for Repair

Moment #13: Ice dam evidence near eaves (winter)

Ice dams can force meltwater under shingles and into the roof deck. Interior staining near exterior walls and eaves is a common clue after freezing weather. Unlike a single broken shingle, this problem is often tied to heat loss, insulation gaps, and poor ventilation. If you see this pattern in winter months, the long-term fix usually involves attic airflow and insulation improvements rather than only patching shingles.
