How to Insulate an un-finished attic and prevent Ice-Dams in a 1920s 2-family home in Cold MA?

Hi everyone! 

I have a 1920s home with an unfinished attic here in snowey Massachusetts. The attic ceiling is un-insulated, with exposed 6" rafters and an asfault tile roof. I was warned about ice-dams and how impropper insulation will lead to a destroyed roof. The problem is I have no idea how to prevent ice-dams -- this is something new to me.

With the wisdom of the community, how can I set up my insulation propperly to prevent icedams?

  1. Is spray on closed-cell foam my best bet?
  2. Do i  need to cut soffit into the attic roofline?  Is there something else I should do
  3. Any other tips or tricks?

Thank you everyone in advance for the input!
