Can Gutter Guards Actually Make Winter Ice Dams Worse? A Roof Expert Explains

Roofing experts warn that while gutter guards are effective at keeping debris out, they may inadvertently contribute to the formation of ice dams during winter. By trapping heat or altering water flow, these systems can cause melting snow to refreeze at the roof's edge. Homeowners in cold climates should carefully evaluate their roof ventilation and insulation before installation to ensure that water drainage remains unobstructed throughout the freezing season.
