The Truth About Ice Dams: Protect Your Roof Before They Start

Ice dams can turn winter wonderlands into water-damage disasters. Understanding how they form—and how to prevent them—is essential for Buffalo homeowners.

What Causes Ice Dams

Snow on a warm roof melts and refreezes at the colder roof edge, creating a ridge that traps water. That water can seep under shingles, leading to leaks, rot, and interior damage.

Prevention Starts in the Attic

Proper insulation and ventilation keep your roof cold and prevent uneven snowmelt. Sealing gaps in the attic reduces warm air escaping, which is the main driver of ice dam formation.

Install Ice-and-Water Barriers

These barriers along roof edges and valleys provide extra protection against leaks caused by trapped meltwater.

Regular Snow Removal

Careful removal of excess snow prevents heavy buildup and reduces ice dam risk. Professionals can safely remove snow without damaging shingles.
