Ice dams form when heat escaping into the attic melts snow that refreezes at the cold eave. The fix is attic insulation and ventilation, not gutter heaters.

Oklahoma ice storms load gutters far past rated weight, which is a separate problem from damming. Air sealing the attic floor matters more than adding insulation on top of leaks. Damage often shows in spring as a leak rather than in January as an obvious failure.
