In Atlantic Canada, what actually ends ice‑dam call‑backs: air‑sealing, exterior foam, or heat cables?
Seal up your attic and add insulation to stop those ice dams caused by a warm roof. If you’re re-siding, exterior foam is a good move. Heat cables? They’re just a temporary fix, melting channels, not fixing the real problem. Cut down on heat loss first, and you’ll have fewer issues later!
