Ice Dams and Gutters in Tennessee

Ice dams form when heat escaping through your roof melts snow on the upper portion of the roof. That meltwater runs down to the colder eave area (over the soffit), where it refreezes. Over time, a ridge of ice builds up that traps water behind it.

While East Tennessee doesn't get heavy snow, the region's frequent freeze-thaw cycles in winter can create ice dam conditions. Temperatures often swing above and below freezing within the same day during December through February.

Ice building up in and around gutters adds tremendous weight. Gutters are designed to handle water, not hundreds of pounds of ice. The weight can pull gutters off the fascia, bend hangers, and crack seams.

When water is trapped behind an ice dam and has nowhere to go, it can back up under shingles and leak into your attic, walls, and ceilings. This is one of the most expensive types of water damage a home can sustain.

Proper attic insulation and ventilation are the primary defenses against ice dams — they prevent the uneven heating that starts the cycle. On the gutter side, properly pitched gutters that drain completely reduce the amount of standing water that can freeze.

Leaf guards also help by keeping debris out that would otherwise trap water and create freeze points. If your gutters are clean and draining properly going into winter, they're much less likely to suffer ice damage.
