Roseville Knowledge · Era-SpecificWhy Ice Dams Keep Coming Back on Owasso Hills and Snelling Corridor Homes
Heated eave cables, more shovel work, third re-roof in 15 years — and the ice dam still comes back. The real fix is in the attic, not on the roof.

Why 1960s ranches are the worst offenders
Low-slope eaves + R-19 original insulation + unbalanced ventilation.
What we measure when we inspect the attic
R-value depth check, top-plate air-sealing, soffit-to-ridge ventilation ratio.
Why heated eave cables are a band-aid
They melt the dam — but the heat loss that caused it is still there.
The 3-step durable fix
Air-seal top plates, add R-49 cellulose, balance soffit/ridge ventilation.
Cost ballpark for a typical 1960s Roseville rancher
$2,500–$4,500 for the full air-seal + insulation + ventilation package.
