The loop
Warm attic melts snow → water runs to cold eaves → ice dam forms → gutters freeze solid → more overflow behind siding.
Clearing gutters in fall helps; it does not replace ice membrane and ventilation on the roof.
Heat cables — limited role
Cables can keep a temporary channel open. They use electricity, can fail, and do not fix heat loss into the attic.
We discuss cables as a band-aid when a full roof scope is months away — not as the permanent plan.
Lasting fixes
- Ice & water at eaves and valleys
- Balanced soffit and ridge ventilation
- Sound drip edge and fascia
- Gutter pitch and capacity matched to the roof
