Roof Replacement in Chicago: Harsh Winter Protection for the Midwest
Chicago's extreme weather swings from bitter winters to hot summers create intense demands on roofing systems. Ice dams, lake-effect snow, and powerful winds require careful material selection and installation practices.
Chicago Climate Extremes

Ice Dam Prevention
Ice dams are Chicago's signature roofing challenge.
Ice and Water Shield: Extended coverage (3-6 feet from eaves) prevents ice dam leaks.
Proper Ventilation: Balanced ventilation keeps roof cold and prevents ice formation.
Adequate Insulation: Properly insulated attics prevent heat escape that causes ice dams.
Roof Design Considerations: Adequate slope and proper drainage reduce ice dam risk.
