❄️ Ice dams form in January, but the conditions that cause them are usually set up months earlier.
Poor attic insulation, gaps in the roof deck, and uneven heat loss all let snow melt unevenly once winter hits. That meltwater refreezes at the roof edge and backs up under the shingles. By the time you see the ice, the damage underneath may already be done.
A fall inspection catches the setup, not just the symptom.
