Ice Dams and Winter Roof Care for Denver Homes
Why ice dams form on Colorado roofs and simple steps to reduce winter roof damage.
November 12, 2026
Colorado properties work hard through intense sun, snow, hail, wind, and quick weather changes. A sound plan starts with understanding the condition in front of you.
How ice dams form
Heat escaping into the attic melts snow on the upper roof. The water refreezes at the colder eaves, building a ridge of ice that can push water under shingles.
Prevention starts in the attic
Balanced insulation and ventilation keep the roof deck cold and even, which is the most reliable way to reduce ice dams.
Before the snow
Clean gutters, check flashing, and have any loose or damaged shingles repaired before heavy storms.
Stay safe
Never climb onto an icy roof or chip ice with tools. If you see heavy icicles or interior water stains, call a professional.
