Does spray foam insulation prevent ice dams?

When should you turn on roof heat cables?
When should you turn on roof heat cables? Roof heat cables are designed to prevent ice dams from forming. They work best if you turn them on about an hour or two before the snow is expected to start falling. This helps warm the roof up so that the snow will melt immediately as it falls on it.
